摘　　要：高速重载工况下的面齿轮测试对试验台的性能要求很高,为了简化试验条件并降低试验成本,基于相似理论并采用量纲分析法推导出了面齿轮齿根弯曲应力和振动加速度的相似准则。通过试验测得相似工况下面齿轮的齿根弯曲应力和振动加速度,利用相似准则建立的面齿轮原型与相似模型参数的相似缩比关系估测实际高速重载下的弯曲应力及振动加速度,实现了高速重载面齿轮强度和动态性能的预测。The test of face gear transmission under the high - speed and heavy - load requires high per- formance test equipment. In order to simplify the experiment condition and reduce test cost, the similarity theo- ry of the tooth root bending stress and vibration acceleration is obtained based on the dimensional analysis theo- rem. The tooth root bending stress and vibration acceleration of face gear under high -speed and heavy -load conditions are measured by the experiment. The bending stress and vibration acceleration of face gear under high - speed and heavy - load conditions are estimated by using the analogical relationship between the face gear prototype and the similarity model establishing with similarity criterion. The prediction of strength and dynamic performance of high - speed and heavy - load face gear under the is realized.
