目的 明确加速度计输出信号中包含哪些加速度信息 .方法 根据加速度计的力学模型求出加速度计输出信号的解析表达式 .结果与结论 加速度计输出信号中包含如下 4种加速度信息 :运动物体质心加速度 ,测试点相对质心的各阶振动加速度 。
Aim\ Explaining which information of acceleration are included in the output signal of an accelerometer. Methods\ Deducing analytic formula of its output signal according to the physical model of an accelerometer. Results and Conclusion\ There are four types of information as follows in the output signal of an accelerometer: the acceleration of the centre of mass of moving object; vibration accelerations caused by the position of the accelerometer fixed versus the centre of its mass; the response of on acceleration the structured part fixing the accelerometer and the response of the accelerometer on excitation.
