摘　　要：文中基于正向设计思路,对振动筒压力传感器振荡系统进行了理论分析、仿真设计和实测验证。重点论述了阻尼、压电陶瓷片性能指标和振荡系统的建立条件等影响系统稳健性的因素,并结合工程化实践给出了有效提高传感器合格率和性能稳定性的设计建议。In this paper,based on the forward design idea,the vibration system of the vibration cylinder pressure sensor was analyzedtheoretically,designed by simulation and verified by actual measurement.The factors affecting the robustness of the system,such as damping,performance index of the piezoelectric ceramic plate and the establishment condition of the oscillation system,were emphatically discussed,and the design suggestions for improving the pass rate and performance stability of the sensor were given.
