摘要

用数值模拟的方法对应变式压杆压力传感器系统进行仿真

研究压杆的变截面对应变式压杆压力传感器测试结果的影响;数值模拟了不同上升前沿的梯形脉冲和三角形脉冲条件下变截面压杆的响应误差。与非变截面压杆相比

变截面压杆的应力波幅值和波形均发生了很大变化

无论梯形脉冲还是三角形脉冲

变截面压杆的应力波幅值都要降低。模拟结果对实验测试结果的分析有一定参考价值。

Abstract

The numerical simulation method is applied to analyze the pressure bar system.The effect of the variable section on the pressure bar is studied.With numerical simulation

the response of different rising front of trapezium impulse and triangle impulse is studied.Compared with the non-variable section bar

the amplitude and waveform of stress wave has been altered greatly in the variable section bar.Regardless of the trapezoidal pulse or triangular pulse

stress wave amplitude should be decreased in the variable section bar.The simulation results have certain reference value for analysis on experimental result.
