基于ABAQUS的仿生导轨摩擦学特性研究

Tribological Properties of Biomimetic Rails Based on ABAQUS

以往复运动摩擦副为研究对象,通过ABAQUS有限元仿真,对比研究了仿生导轨与普通导轨的摩擦力分布、摩擦副温度、磨损状态等摩擦学性能。结果表明,普通摩擦副的摩擦力分布更加集中,仿生摩擦副则相对分散。普通摩擦副上低温区面积较大,仿生摩擦副低温区较小,仿生单元使得导轨上的温度分布更加均匀,最高温度也有所下降。仿生摩擦副的磨损较为均匀,磨损率明显低于普通摩擦副。

The object is reciprocating friction in this study. Comparing with contrast bionic and ordinary rail by ABAQUS, the tribological properties were studied, such as distribution of friction, temperature friction and wear status. The results indicated that the friction distribution of ordinary rail was concentrated, and the bionic friction was fragmented. The low temperature area was larger on ordinary rail, and low temperature area was smaller on bionic ordinary rail. The temperature distribution was more uniform becausing bionic u-nit on the rail, and the maximum temperature was also fell. The friction wear was more evenly on bionic rail, and the wear rate was significantly lower than ordinary friction.
