加速度场中工作的六维力传感器软件设计

Software design of six-dimension force measure in centrifuge's acceleration field

六维力传感器处于加速度场中,其自身受到惯性载荷作用产生的力信号和被测试件产生的力信号混合在一起,传感器系统很难准确给出被测试件产生的受力(矩)情况。本文分析了六维力传感器在离心加速度场中工作的受力情况以及测量工作原理,给出其在加速度场进行力(矩)测量的解耦方法,在此基础上,开发了一套可应用于离心加速度试验的六维力传感器测量软件。经过试验验证,证明该软件可成功用于离心加速度六维力传感器的动态测量。

It is difficult for a force sensor to measure the force when it is in the centrifuge acceleration field.Basing on the fundamental principles on the force measurement and the force analysis of a six-dimensional force sensor in centrifuge acceleration field,this paper introduces a decoupling method in the force measurement,and develops a set of software for measuring six-dimensional force in centrifuge acceleration field.Test results has validate the effectiveness of this software.
