齿轮箱振动测试与分析

Vibration measurement and analysis of gearbox

在对某型齿轮箱的模态、振动烈度和振动加速度进行测试的基础上,详细分析了测试结果.模态测试得到了齿轮箱的振型和模态参数,振动烈度测试结果表明该齿轮箱处于良好工作状态,振动加速度测试结果显示该齿轮箱的减振措施达到了预期的效果.最后,对测试提出了建议.

On the basis of the measurement of model, vibration severity and vibration acceleration of a certain kind of gearbox, the measurement results are presented in detail. The result of modal mea-(surement) gets the vibration model and modal parameters of the gearbox, and the result of vibration severity measurement makes it clear that the gearbox is in good condition, and the result of vibration acceleration measurement indicates that the vibration reduction reaches the prospective effect. Some advice for the measurement is given finally.
