摘　　要：研究压发装置的精确建模与产品性能优化问题.基于绝对节点坐标方法的缩减板单元对压发装置电路板进行建模,通过实验确定电路板的材料参数及支撑弹簧与触发装置的非线性刚度特性,采用非线性力–位移关系建立了支撑弹簧与触发装置力学模型,搭建了压发装置结构的精确有限元模型;设计了压发装置加载实验系统,采用实验数据验证了上述有限元模型的正确性.根据目标触发载荷范围,优化了压发装置中支撑弹簧的刚度及长度参数.数值模拟直接指导了压发装置参数设计,并已成功应用于型号研制.The accurate modeling and product performance optimization of pressure ignition device were studied.The reduced plate element based on the absolute nodal coordinate formulation was used to model the circuit board of the pressure ignition device.The material parameters of the circuit board and the nonlinear stiffness characteristics of the support springs and the trigger devices were determined by experiments.The mechanical model of the support springs and the trigger devices were established by using the nonlinear force-displacement relationship,and the accurate finite element model of the structure of the pressure ignition device was established.The loading experimental system of the compression ignition device was designed,and the correctness of the finite element model was verified by experimental data.According to the target trigger load range,the stiffness and length parameters of the support springs in the compression device were optimized.The numerical simulation directly guides the parameter design of the pressure ignition device and has been successfully applied to the type development.
