摘要


摘 要:为对惯性开关进行大于8000g的冲击检测,设计了一种便携式冲击试验装置。根据弹性力学的赫兹理论,对该冲击试验装置进行了动力学分析,采用四阶龙格-库塔(Runge-Kutta)算法求解得到了结构参数与冲击特性的关系。采用Endevco2270标准传感器进行标定,标定结果满足设计要求,即该冲击试验装置可产生最大幅值约8400g,脉宽约110μs的冲击加速度信号,在同一高度测试的相对误差小于6%,具有良好的输出稳定性。该冲击试验装置体积小,质量轻,便于携带,维护简单,安全可靠,可用于小尺寸惯性器件冲击检测及抗冲击实验等。

Abstract

Abstract: A portable high-g impactor is designed to test impact larger than 8000g for inertial switch. Dynamic analysis of the impactor is carried out with the Hertz theory of elastic mechanics. Relationship between the structure parameters and the impact characteristic of the impactor are obtained and solved with the tetra-order Runge-Kutta algorithm. Calibration with Endevco2270 shock accelerometer is performed to show the impactor can generate shock acceleration of maximal amplitude about 8400g with impulse width about 110μs. The relative error is below 6% in the test of the same height, which shows the output stability is good. The impactor is small, light, portable and easy to maintenance, can be used to test impact for inertial device in small size and experiment of shock resistance.
