Research on the Simulation Method for I.C.E Structural Acoustic Radiation

Abstract:

By systematical research on the analytic procedure of excitation loads inside the internal combustion engine, the computational method of dynamic characteristics and dynamic response, and the prediction technique of structural acoustic radiation, an approach for structural acoustic radiation prediction of I.C.E based on BEM theory, ATV technique and coupled BEM-FEM method is proposed. It is a new and efficient way to solve the problem of engine’s structural acoustic radiation under multi-operating conditions. The numerical simulation results and measured values through experiments indicate that this approach is scientific, correct and feasible.
