冲击台冲击波形的确定方法

摘要

The problems which due to test whether the shock waveform conform the requirements of the impact test exist in the test efficiency slowly and the waste materials. On the basis of experimental data, this project using Taylor formula and the least square method put the complex physical model into several simple mathematical models. A shock waveform generator simulation selected and impact machine height determination method is given out to determine the shock wave. Examples show that the function model is correct.%本文对冲击台在冲击试验前，因测试冲击波形是否符合试验要求而所做的过多模拟测试，会导致试验效率较低、试验材料浪费等问题，在数据试验的基础上，运用泰勒公式和最小二乘法，将复杂的物理模型转化为若干个简单的数学模型，给出了一种冲击台的波形发生器的模拟选定和冲击台提升高度的确定方法，以确定冲击波形。测试数据表明，该方法建立的冲击波形的确定方法是可靠的。
