摘要
针对某混合动力系统的齿轮啸叫问题进行了分析和优化。基于测试噪声的阶次分析,锁定了齿轮副噪声源。通过接触斑点测试,表明齿轮副存在明显的偏载问题。对接触斑点的仿真和测试结果进行了对标,仿真结果与测试结果吻合较好,该仿真分析模型可用于后续的微观参数优化分析。对一级小齿轮进行了微观修形参数优化,优化后齿轮接触斑点更均匀,传动误差更小,轴承动态响应力也更小。噪声测试结果表明,修形后的齿轮噪声明显降低。
Gear whine noise of one hybrid power system is analyzed and optimized.Based on test noise order analysis,the main noise source is found.The contact patch test also shows that eccentric load phenomenon is obvious.The simulation and test results of contact patch are compared.It shows that the simulation results are coincident with test results,this simulation model could be used for the following micro parameter optimization analysis.The micro parameters of the first pinion gear are optimized.The contact patch of the optimized gear is more uniform,and transmission error is smaller,and the bearing dynamic responses are smaller.Noise test result shows that noise of gear micro modified became lower.
