汽车喇叭机-电-磁-声耦合场仿真方法的研究

摘要

建立了汽车喇叭的机-电-磁-声多场耦合模型,结合ANSYS、ADAMS和FLUX等有限元软件提出了一种汽车喇叭声学特性的仿真分析方法,试验结果验证了该方法的可行性和准确性.进而分析了喇叭参数对声学特性的影响规律.%A coupled model of mechanical, electric, magnetic and acoustic fields for automotive horn is built, and a simulation method for the acoustic characteristics of automotive horn is proposed by combining FEA softwares of ANSYS, ADAMS and FLUX.The feasibility and correctness of the method are verified by test results,and the effects of horn parameters on its acoustic characteristics are analyzed.
