Agitate friction welding (FSW) regard a kind of new-style solid photograph as join technology, have a series of traditions to solder the advantage that cannot compare [1-2] . If solder when without splatter, stress of remains of the workpiece after needing aeriform protection, solder and be out of shape small, solder contact tension is extended function and fight curve function cost of good, production is low wait with free from contamination, these function solder in aluminium alloy the respect has advantaged advantage [3-4] . The issue that agitate friction welding involves temperature field, material to organize the many sided such as meet an emergency of flow of change, data, stress and vibration in machining a process [5-8] . To raise agitate friction welding solder quality, must want to design to be able to detect at the same time the online testing system of Xiang Li and the temperature in process of treatment of agitate friction welding, 3 oscillatory signal. Of the system form agitate friction welding the online system that monitor basically has hardware and software two parts are formed, construction of system is shown 1 times like the graph. The agitate friction welding that hardware part includes proper motion design to make measures meet an emergency of sensor of force anise annulus, K thermocouple, acceleration, resistor piece wait for signal induction component, signature manage circuit, data collects card, computer and jumper means. Software part basically is to use can collect card to undertake corresponding parameter setting and the real time to collecting signal show to data and the operation that data stores LabVIEW is developed installs an interface. The designs annulus of the 1 anise that measure power design agitate friction welding of systematic hardware should produce 3 Xiang Li's effect in machining a process, if pursue,2 are shown. Issue pressure among them bigger; Radial load has constant wave motion; Side force is weaker. The ring of the anise that measure power that accordingly characteristic design makes can detect agitate friction welding is machined 3 Xiang Li, if pursue,3 are shown. The sensor that 2 sensor involve in this system has meet an emergency of thermocouple, resistor piece with acceleration sensor. Thermocouple is to measure lukewarm sensor, k thermocouple structure is simple, heat is inertial small, trends answers speed fast, can remote deferent signal and much dot are measured [9] . It is workpiece of low melting point more considering object of agitate friction welding, so this system uses chromium of 1 class nickel - nickel silicon K of brief outfit type thermocouple, its function index sees a table 1. Because this system is medium,the ring of the anise that measure power that design of proper motion of have the aid of makes completes the process that measure power, so inductive component should satisfy the requirement of span sensitivity already, should facilitate again stick in the composition on anise annulus to measure force transducer. Consider above factor integratedly, this system uses Bx120-2AA resistor strain piece, if its function index expresses 2 to show. Nextpage vibration is measured press sensor of electric type acceleration for ULT2404/V with model, if its performance data expresses 3 to show. This sensor not only have wonderful temperature change to keep apart action, taller resonance frequency and good linear, and structure simple, cost is low, facilitate fixed. What circuit of 3 signal recuperation arises as a result of sensor is fainter voltage signal, but collecting card to collect what data uses to collect voltage originally is 0~10V, the faint signal that generates to sensor for this need undertakes magnifying handling. In addition, thermocouple considers Leng Duan to compensate a problem even, if the graph is shown 4 times,its Leng Duan compensates circuit. The effect that the oscillatory signal that acceleration sensor collects suffers outside ambient is bigger, undertake for this need filter wave is handled, circuit of its filter wave is shown 5 times like the graph. 4 data collect this calorie of system to use grind China PCI, 1710L muti_function data collects card. Should collect clamping apparatus to 16 converter of 12 32 PCI bus line, A/D, Chan Duan or 8 difference divide imitate to measure word of input, 16 a movement in martial arts to input, sampling rate can amount to 100kHz. Collect card to have function of Plug and Play, do not need to install any jumping line and DIP dial a switch; Measure precision tall, rate is rapid; Process designing is simple, join is convenient, and have good interface with LabVIEW. In addition, this system still was in efferent leg part to install short circuit to protect parts of an apparatus, can collect card to undertake short circuit is protected to much data. The operation software that systematic software designs this system is to be based on what programming language LabVIEW is developed and can become, design of face plate of the operation before cent is and programming two parts. The parameter setting that uses corresponding function module to finish pair of data to collect card and whole data collect the drill of the process to accuse, the real time that realizes data is collected, show reach memory [10-11] . 1 before the agitate friction welding that operates the design of face plate to be based on LabVIEW to write operates face plate before the online system that monitor, if pursue,6 are shown. Does face plate have: of the following function before? of Xian fir whizs badger looks allow of Zu of of ⑹ of Pi of Piao of of Yao of personal apprentice uses up uncut jade of ⒉ fir to lose of fir of ⒉ of Chi of ≡ of Lai Nan of ǖ of canister fir to ask of ⑹ of ā of accept Zan Chun defend to play makes an appointment with fat of the ⒙ that press Wa to wrap up accept Zan. Data collects 2 programming systematic main program is shown 7 times like the graph, use corresponding function child module undertakes circular sampling to the signal of each passageways, the collection that basically realizes data, amortize, show reach the function such as memory. Nextpage (1) the collection of data and show. PCI, 1710L muti_function data collects card to take LabVIEW driver oneself, apply LabVIEW8. 5 in relevant data collects module and the much passageway data that collect function to collect function, can very gather the information such as each signal and its passageway index conveniently, and can pass the data that collects weaveform directly show accuse an intuitionistic ground to show come. If the graph is shown 8 times,data collects a process. Above all, use DeviceOpen function (graph 8 (A) ) open data gathers facility and pass MuiltiChannelINTSetup subprogram (graph 8 (B) ) undertake much passageway imitate inputs parameter setting; Next, use EnableEvent function (graph 8 (C) ) begin data to collect, pass BufferChangeHandler at the same time (graph 8 (D) ) open up a buffer with cache data, after the data that enters cache area is compensated through function at the same time, show with undee form directly showing accuse on, use data to write function to keep data designation file at the same time; Finally, through FAIStop function (graph 8 (E) ) stop data to collect and use DevieceClose subprogram (graph 8 (F) ) shut gather facility. (2) the memory of data. To facilitate the processing of later period data, the data that enters cache area must be written into appointing a file through corresponding function. LabVIEW is written mediumly measure file function (graph 9 (A) ) in can keeping the data of cache designation file with LVM format. Because data gathers speed very big, so, complete ground keeps the data that the data in collecting a process must assure to be collected through amortize ability in appointing a file. Function cites through getting alignment in this system (graph 9 (B) ) build alignment of amortize of a data, use at the same time get alignment condition function (graph 9 (C) ) advanced face plate shows the memory state that collects data process squadron line intuitionisticly come, the data in preventing to collecting a process quickly so loses an issue. Systematic test and analysis used this system to undertake to 7022 aluminium alloy agitate friction welding solders those who receive process signal is online monitor. The temperature that differentia is apart from to be apart from welding line in experiment process undertook metrical, if temperature curve pursues 10 (A) be shown, from this the curve can see the temperature peak value that is apart from welding line differentia is different apparently, peak value of closer from welding line temperature is higher and temperature of highest peak value is controlled in 250 ℃ ; Graph 10 (B) to solder the oscillatory signal curve that measures in the process, analyse data conform to with theory; Graph 10 (C) the 3 Xiang Li curves in machining a process for agitate friction welding, by this curve we can be seen, soldering normally next pressure in the process have constant wave motion, and numerical value is greater, radial load is stabler, radial load size tends calm value, and side force is very small. Actual application makes clear, this system can finish agitate friction welding in time to machine signal, oscillatory to temperature signal and the real time of 3 Xiangli signal in the process to show, collect and store. The article is based on the last word LabVIEW8.
5 finished agitate friction welding the design of the online system that monitor. Deserve to use grind China PCI, 1710L muti_function data collects card to make this system can machine the temperature in the process to agitate friction welding signal, oscillatory signal and 3 Xiangli signal undertake real time is collected, show with memory, and this system has a structure simple, cost low, interface the advantage such as friendly, facilitating operation.
