摘要

为了更有效地降低人字齿轮传动系统的振动,提出分别从人字齿轮传动系统振动产生的源激励(齿面啮合质量)和振动传递(箱体结构)两方面对系统进行减振降噪设计。选择修形综合效果较好的齿面三维修形方法,在多载荷工况下对人字齿轮小轮齿面进行以减小轮齿间啮合振动为目标的修形优化设计;为确定箱体结构优化改进方向,首先对齿轮箱体进行以静态(箱体最大变形量)动态(低阶固有频率)相结合的结构拓扑优化,再根据箱体拓扑优化结果确定箱体可以减重部位以及需要加强的结构,最后据此选定箱体尺寸优化参数并对箱体进行以箱体机脚处振动加速度均方根值最小为优化目标的箱体结构优化。实例计算与试验结果表明,齿面三维修形方法振动最大降幅理论计算为20.5%、试验实测为18.9%,箱体结构优化方法减振12%,而两者相结合则取得更好效果,降低幅度达27.3%。

Abstract

In order to reducing the vibration of herringbone gear transmission system more effectively, vibration reduction design methodsare put forward respectively from vibration excitation source of herringbone gear transmission system (tooth meshing quality) and vibration transmission path (box structure). Tooth surface three-dimensional modification is choosen to optimizing the vibration between the herringbone gear meshing teeth under multi-loads. Topology optimization is carried out target with static (box deformation) and dynamic (lower natural frequency) in order to improve the gearbox dynamics structure, and the optimization results can indicate which parts of redundant material and which structure needs to be strengthened. Accordingly, gearbox structural size is optimized to obtaining minimum acceleration of gearbox feet. Example calculations and experimental results show that the method of tooth three-dimensional modification reduce vibration of 18.9% by experiment test and 20.5% by theoretical analysis,the method of gearbox structural optimization reduce vibration of 12%. The better effect of 27.3% decline is obtained by combination of two methods.
