车辆 轮胎 多边形磨损 变刚度 机理
2010/12/29
考虑轮胎接地摩擦的非线性特性，建立了基于侧向变刚度的轮胎多边形磨损模型，并对系统的稳定性进行了分析，指出轮胎的自激振动是一种由系统Hopf分岔引起的稳定周期振动现象，通过数值仿真得到了引起胎面自激振动的车速和车轮前束角范围。结果表明：轮胎多边形磨损为一种典型的非线性自激振动现象，其发生与胎面的侧向振动有关，磨损边数近似等于胎面的侧向振动频率与车轮转动频率之比。所建模型能够很好地解释轮胎多边形磨损的...

激光微造型凸轮副的摩擦磨损（Friction and Wear of Cam with Laser Micro-texture under Lubrication）
凸轮 激光微造型 几何形貌
2010/1/28
采用UMT-2多功能摩擦磨损实验机，模拟内燃机凸轮/滚轮工况条件，考察了多种激光微造型形貌试样表面的摩擦磨损特性。实验结果发现，与未处理光滑表面相比，激光微造型试样表面的耐磨、抗擦伤性显著提高，其中，凹坑造型表面的摩擦因数显著下降，而凹槽表面的摩擦因数相对较大。这说明凹槽形貌会增大表面摩擦，而凹坑形貌具有一定的减摩效果。合理选择凹坑的深度及其面积占有率，并进行微形貌几何参数的优化组合，可达到最佳减...
