摘要
考虑到齿轮传动系统的工况复杂性以及齿轮故障实验存在周期长、成本高的问题,采用SolidWorks三维建模软件建立了齿轮箱各部分三维实体模型,并分别建立了裂纹、断齿故障齿轮模型.利用ANSYS对研究的齿轮进行了柔性化处理,并对正常齿轮与齿轮裂纹、断齿模型在稳定工况与变速工况下进行了ADAMS动力学仿真.通过分析故障状态下齿轮振动加速度的时、频域图,结果表明,在稳定工况下,断齿齿轮产生的振动最剧烈,呈周期性,裂纹齿轮会在运转初期产生较大振动;在变速工况下,随着速度的增加,齿轮产生的振动幅度越来越大,而随着速度的减小,振动幅度越来越小.
Abstract
Considering the complexity of the working conditions of the gear transmission system and the problems of long cycles and high costs in gear fault experiments,SolidWorks 3D modeling software is used to establish 3D solid models of each part of the gearbox,and crack and broken tooth fault gear models are respectively established.The studied gears are treated with flexibility using ANSYS.ADAMS dynamic simulation is conducted on normal gears and gear crack and broken tooth models under stable and variable speed working conditions.By analyzing the time-frequency domain diagrams of gear vibration acceleration under fault conditions,the results show that under stable working conditions,the vibration generated by broken tooth gears is the most severe and periodic,and the cracked gears will generate significant vibration in the early stage of operation.Under variable speed conditions,as the speed increases,the vibration amplitude generated by the gear becomes larger,and as the speed decreases,the vibration amplitude also becomes smaller.
