Finite element analysis based on PKE system of electromagnetic fields inside the vehicle

摘要

In order to analyze the passive keyless entry (PKE) electromagnetic field distribution, the three-dimensional finite element analysis method is used in the paper.By introducing threedimensional finite element analysis method,we establish the modeling and simulation of the system, and select the appropriate boundary conditions ,mesh options and the partition method for the solving domain. The simulation results show that by this means, we could obtain the distribution of the three-dimensional vehicle electromagnetic field affected by the universal antenna, and analyze the local electromagnetic field distribution in the critical region. The simulation model bosed on the finite element method can effectively solve the electromagnetic field distribution in the carbody region, and provide a new solution to the simulation problem based on PKE system.
