摘要
机场跑道摩擦系数是评价机场跑道道面质量的重要参数。在考虑冬季跑道道面压实雪厚度和摩擦热形成的润滑水膜作用下建立了冰雪道面半融状态摩擦系数计算模型。使用Matlab数值仿真软件对所建模型进行了仿真。数值仿真结果表明,摩擦系数模型建模合理,摩擦系数计算数据与实测数据比较吻合。对摩擦系数的测试实践有一定的理论指导意义。
The friction coefficient of runway on snow and ice surface partially melted is the key quality. Theoretical calculation model of frictional coefficient is developed in which the thickness of compacted snow and the length of water film formed by friction heat were added, and the friction coefficient model was simulated with Matlab software. The simulation result is more close to the actual tested data. The model is reasonable and useful for the measurement runway friction coefficient on snow and ice surface.
