摘要

为了研究张紧器对同步带传动噪声的影响规律

针对ZA型汽车同步带建立了三轮一带传动系统的有限元分析模型。首先分析了三轮一带传动系统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

其次基于声学边界元理论直接边界元法建立了三轮一带传动系统的声学边界元仿真模型

得到同步带表面声压分布云图及场点辐射噪声。设计了三轮一带噪声试验台

并对三轮一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。结果表明:在非共振区

4个场点噪声变化规律一致

且随着啮合频率增加

噪声幅值增加; 在共振区

共振噪声的噪声幅值会有不同程度的增加

与理论分析结果相同; 共振频率下的噪声源主要集中在带段中间

非共振频率下的噪声源集中在主、从动轮及张紧器位置附近。研究验证了仿真计算结果的准确性与可行性

得到张紧轮对同步带传动系统噪声的影响规律。

Abstract

Aiming at the influence of tensioner on transmission noise of the synchronous belt

a finite element analysis model of three-pulley one-belt transmission system for a ZA type synchronous belt is established. The dynamic response of the three-pulley one-belt transmission system under meshing impact is analy-ed

and the result is taken as the boundary condition. Following the acoustic boundary element theory

an acoustic boundary element simulation model of the three-pulley one belt transmission system is established by the direct boundary element method. A noise test bench is designed and test is conducted to compare the testing results of radiated noise with numerical simulation results. It is found that: in the non-resonance -one

the four field points obey the same rule of noise change

and with the increasing meshing frequency

the noise amplitude increases. In the resonance -one

the amplitude of the resonance noise increases to different degrees

which coincides with the theoretic
