| 中文摘要: |
| 目的 飞行器试验时，滑靴会因为与轨道间强烈的摩擦热、气动热以及接触表面微观粗糙峰间的相互高速冲击而产生磨损、温升、凿削等损伤，针对这种情况，利用数值模拟软件进行研究，以解决目前通过实际手段无法有效检测滑靴烧蚀的难题。方法 利用Comsol Multiphysics高级多物理场有限元仿真软件对靴轨摩擦副建模，主要分析滑靴在不同速度、不同载荷下由于摩擦生热产生的温升现象。结果 滑靴的具体烧蚀情况会随着施加速度、载荷的不同而有差异；其中，滑靴在最高速度为300 m/s时开始烧蚀的时间比最高速度为100 m/s时提前了1 s；而载荷对滑靴表面温度的大小略有影响。结论 为滑靴的合理设计提供了理论依据。 |
| 英文摘要: |
| In the test of the aircraft, the friction between the sliding shoe and the track due to strong frictional heat, aerodynamic heat, and high-speed impact of the micro-rough peaks on the contact surface causes wear, temperature rise, chiseling and other damage to the shoe. The paper aims to research with numerical simulation software to solve the problem that the current method cannot effectively detect the ablation of sliding shoe. Comsol Multiphysics advanced multiphysics finite element simulation software was used to model the shoe-rail friction pair, and analyze the temperature rise of sliding shoe due to frictional heat generation under different speeds and different loads. The specific ablation situation of the slide shoe varied with the applied speed and load; among them, the ablation time at the highest speed of 300 m/s was 1 s earlier than that at the highest speed of 100 m/s; and the load slightly affected the surface temperature of the shoe. This study provides a theoretical basis for the rational design of sliding shoe. |
