用有限元方法对应变式压杆压力传感器系统进行研究，研究3种不同材料的压杆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及三角形脉冲条件下不同材料压杆的响应误差。研究结果表明，铍压杆对测试结果的影响最小，铝合金压杆影响最大；另外，脉冲上升前沿和测量位置对测试结果的影响也很大。模拟结果对压杆材料的选择有一定参考价值。

The finite element method is applied to analyze the strain type pressure bar system.The effects of three different materials of the pressure bar on measure results obtained by the strain type pressure bar system are studied.By numerical simulation,the response errors of pressure bars with different materials under different rising front of trapezoidal impulse and triangle impulse are investigated.The results show that the influence of the beryllium pressure bar on the measure results is minimum and that of the aluminum alloy pressure bar is maximum.In addition,the impulse rising front and measuring position have great influence on the measure results.The simulation results can provide some references for choosing the material of the pressure bar.
