航空轮胎胎面胶等效工况磨损特性研究

Study on Wear Characteristics of Tread Compound of Aircraft Tire under Equivalent Conditions

使用自主研制的航空轮胎等效摩擦磨损试验平台对航空轮胎不同服役工况下的摩擦行为进行等效拆解,研究加载条件对加速起飞、着陆瞬间和制动滑行摩擦工况对胎面胶磨损特性的影响。结果表明:3种工况中,制动滑行是航空轮胎胎面胶快速磨损的主要工况,制动滑行工况下胎面胶磨损率明显大于加速起飞和着陆瞬间工况下;等效摩擦磨损试验平台可实现航空轮胎胎面胶摩擦行为的模拟,可作为高耐磨胎面胶配方开发的评价工具。

Using a self-developed equivalent friction and wear testing platform designed for the aircraft tire,the friction behavior of the aircraft tire under different service conditions was decomposed equivalently,and the effects of loading conditions of accelerated takeoff,landing instantaneous and brake skidding on the wear characteristics of the tread compound were investigated.The results showed that among three conditions,brake skidding was the primary condition for rapid wear of the tread compound of the aircraft tire,the wear rate of the tread compound under brake skidding condition was significantly larger than that under accelerated takeoff and landing instantaneous conditions.The equivalent friction and wear testing platform could effectively simulate the friction behavior of the tread compound of the aircraft tire and could be used as an evaluation tool for the development of the highly wear-resistant tread compound.
