Abstract
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.
