摘　　要：针对传统爆破管压力测试装置由于其传感器结构无法实现小体积的缺陷,设计了一种壳体电容式压力传感器。介绍了测压器的结构及基本原理,并利用ANSYS软件对测压器进行了静力分析及瞬态压力仿真,利用MATLAB进行了数值拟合;在模拟膛压发生器上进行动态实验,对得到的压力曲线进行分析。分析表明,该测压器压力响应良好,可以推广到实践中。For the defect problem of small size sensor structure, the traditional pipe burst pressure testing device cannot achieve the small volume effect, so a housing capacitive pressure sensor is designed. The article introduces the structure and the basic principles of this sensor and the static analysis and pressure transient simulation is made on manometer using ANSYS software and the numerical fitting is done with MATLAB. The dynamic experiments on simulation chamber pressure generator are made to analyze the pressure curves obtained. Analysis shows that the manometer pressure response is good; it can be extended to practice.
