Dynamic Simulation and Analysis of Free Piston Stirling Generator with Shell Shock Absorption Mode

Abstract

With a view to investigating the stiffness and external vibration disturbance of the free piston Stirling generator, a model of hot-machine-electric coupling system dynamics in shell vibration state is built in this paper for typical free piston Stirling power system, by theoretical analysis of thermodynamics and kinetics. Differential equations of hot-machine-electric coupling system are built, and the influence of stiffness and environmental excitation on dynamic performance and operational status of the system is also analyzed.
