Torsional Vibration Analysis and Optimization of Vehicle Multi-stage Planetary Transmission System

  • 摘要: 针对某高速履带车辆七档行星传动系统匹配问题,利用集中质量法建立了等效扭振模型,分析了扭振系统无阻尼自由振动固有频率和振型对转动惯量及刚度的灵敏度。结合行星变速机构的固有特征和内外激励频率,分析了行星变速机构各档位的共振情况,并基于灵敏度分析对扭转模型进行了动力学参数的优化。仿真实验的结果表明,优化后的动力学参数可较好地避免扭转振动。研究结果为进一步分析行星传动系统匹配对扭转振动的影响及改进扭振性能具有一定指导作用。
