| 摘 要： | 为优化压电式加速度传感器设计，提高其量程，用瞬态动力学仿真软件Msc.dytran对中心压缩型压电式加速度传感器在导弹碰靶过程中的加速度和动态应力进行模拟仿真。结果表明：对于结构一定的传感器，压电片厚度存在一个最佳值，可以通过仿真选择较好的材料组合（如，基座选铝、压电材料选石英）来减小透射到压电片中的应力波强度，以提高传感器的量程。

| Abstract: | In order to optimize the piezoelectric senor design and enhance its measurement range,with the nonlinear transient dynamics finite element analysis software Msc.dytran,the acceleration and dynamic stress of the sensor fixed on a missile are simulated.The result indicates that the piezoelectric transducer has a best thickness,simulation can help to select a better material combination to induce the stress wave in the piezoelectric transducer,so that the measurement range can be increased. |
