摘要

针对ZA型汽车同步带建立了汽车同步带传动系统的有限元分析模型,采用有限元方法分析了汽车同步带的固频特性和在啮合冲击激励作用下的动态响应。并以动态响应结果作为边界条件,基于直接边界元法建立了汽车同步带传动系统的声学边界元分析模型,分析了啮合激励频率对同步带表面声压及场点辐射噪声的影响规律。并采用两轮无负载试验方式对同步带传动系统进行了噪声测试,比较辐射噪声的测试结果与数值仿真结果,验证了仿真计算方法的准确性与可行性。

Abstract

A finite element analysis model of the ZA synchronous belt drive system is established. Through the finite element method,the natural frequency of the automobile synchronous belt and its dynamic response under the action of meshing impact excitation are analyzed. And based on the dynamic response results,the acoustic boundary element analysis model of the transmission system of the automobile synchronous belt is established by the direct boundary element method,the influence law of meshing excitation frequency on the synchronous belt surface sound pressure and field radiated noise is analyzed. The noise test of the synchronous belt drive system is carried out by using two wheel load test method. Comparison of the radiated noise and the numerical simulation results,the accuracy and feasibility of the simulation method is verified.
