PRECISION CENTRIFUGE TESTING SYSTEM

DESCRIPTIONS

Introduction of accelerometer functional test system:<

The accelerometer functional centrifugal testing system is mainly used for the qualitative analysis of the accelerometer within therange to ensure the pass rate ot the product in the range precision lest, The functional centrifuge generates centrifugal force in theprocess of rotation , f= ma , a = w2r. Our accelerometer is installed on the centrifugal arm , and the output of the accelerometerincreases with the increase of the speed w . Since the output value of the accelerometer is Dc curent ,the stability and accuracy ofthe current are closely related to the Ac component of the DC current. lf there are more Ac components in the Dc signal, thesianal will be unstable. We collect the voltage at both ends of the sampling resistance through the osciloscope , and the Accomponent will be very clear.

Product component:

The centrifuge is composed of a mechanical table , a measuring and control cabinet and an industrial computer, which is mainlyused for the calibration of acceleration sensors and the acceleration stress screening test. it has smooth speed control ability. Theequipment adopts box type , the box cover is made into a semi-open (clamshell) state , and the box cover is closed when thecentrifuge is working. To ensure safety, a touch switch is set at the cover of the container. lfthe cover is not covered , the devicecannot be powered on .←Dimensions: 1 .2mx1 .2m square; The height of the working table (including the height of the cushion iron) is about 800mm .

System reliability:

The whole measurement and control system adopts the modular structure form, and according to the function of the systemcombination. Each module has a relatively independent function , and adopts the mature technology of our related fields . Thedigital sianal connection between modules is adopted. The structure is compact, the reliability is high , and the expansion ability isstrong , which is easy to update and maintain. With digital control mode , high integration and good reliability, the whole process ofautomatic testing can be carried out through the control computer. The computer operation interface is designed as a friendlyinterface of Chinese window, and the operation is simple and convenient , The svstem has perfect safety protection funcion , fault.tolerant desian and aood reliability, which can protect the centrifuge speedina , over-limit , emeraency power failure andunforeseeable abnormal state to ensure the safety of the platform and the measured parts .
