Analysis and Research on Thermal-Force Coupling Performance of a Vehicle Controller PCB Board

Based on the basic theory of thermodynamics and finite element, taking PCB of as the research object of a vehicle controller, the thermal characteristics and structural mechanics simulation are carried out. The distribution of temperature, thermal stress and deformation and thermal-force coupling performance of PCB are obtained, so as to provide a reference for the design optimization of the subsequent circuit board, the selection of heat dissipation mode and the installation position.
