Research On Smooth Loading Control System Of Force Standard Machine

Force standard machines are standard values and standard dynamometer used forcalibration of the machine, is a national force measurement and value benchmark in the fieldof equipment. It involves the entire measurement area, and is required by law, to themeasuring direction, supervision, to ensure that the role of. Shizushige force standardmachine is a kind of force standard machine with high precision, its performance indexdetermines the accuracy of national metrology and measurement industry as a whole, nationalscientific and technological, economic, military and other fields is of paramount importance.Reasons of force standard machine because of its structure, work in the verificationprocess, the load needed in order to reach a certain value, a weight during the loading processyou will need to uninstall, it is called the " inverse process " phenomenon." inverse process "phenomenon will affect the accredited calibration of sensor accuracy.This paper in the past deadweight force standard machine loading and unloading workprinciple and movement analysis based on deadweight force standard machine madefull-closed loop control. This on Shizushige type force standard machine of machinerystructure for has more full of analysis, established has static heavy type force standardmachine of machinery structure dynamics model, this based above, further established hasstatic heavy type force standard machine full closed ring control of mathematics model,through on closed ring control mathematics model of simulation analysis, confirmed has staticheavy type force standard machine full closed ring control way phase for open ring controlway improve has verification precision, and the control way phase for other loaded way ofstatic heavy type force standard machine improve has system of can controlled sexual,Effective and controlled the deadweight force standard machine in the fluctuations in thevalue of the calibration process. This building was designed on the basis of the mathematicalmodel for closed-loop control based on DSP for deadweight force standard machinefull-closed loop control system through the system, achieving two pieces combined loadingand unloading of weights, effectively avoid the deadweight force standard machine in theprocess of verification of the return behavior, increased deadweight force standard machineinspection accuracy.
