Mechanical Analysis: Solutions to Instantaneous Acceleration and Cushioning Time of Accelerometer’s Collision
A novel and simplified method, which is useful in calibrating instantaneous acceleration and cushioning time of accelerometers after impacted by an object under different parameters’ condition, is proposed in this paper. An investigation on cushioning time, which is usually difficult to be quantified during the process of collision, has also been conducted. Firstly, by mathematical inference on a physical model, we obtained two formula conclusions. Next, numerical simulation suggests that the instantaneous acceleration and cushioning time, to different extent, are sensitive to six factors. Then, influences produced by each of them are studied one by one. By analyzing these influences, the method and results are proved to be correct and practical.
