机械运动参数电测实验是为机械原理这门学科而设置的一个基础性实验。用电测法测定机械量的过程,其实质和手段是将机械量(例如:位移、速度和加速度)的变化,通过一定的传感器转化为电参量(例如:电流、电压等)的变化,再经过中间电路将微弱的电信号进行变换、放大,然后再用显示器加以显示或记录。过去实验中突出的缺点是实验手段落后, Mechanical motion parameters Electrical test is a basic experiment set for the discipline of mechanics. The essence and means of determining the amount of mechanical power by electrical measurement is to convert the changes of mechanical quantities (such as displacement, velocity and acceleration) into the changes of electrical parameters (such as current, voltage, etc.) through certain sensors After the weak electric signal through the intermediate circuit to transform, enlarge, and then use the monitor to display or record. The outstanding shortcoming in the past experiment is that experimental means are backward,
