摘要
随着我国民航业的快速发展,飞机起降安全问题是机场当局面临的重要考虑和挑战。轮胎与跑道接触面上产生的摩擦力被认为是飞机安全着陆的关键因素,而对于摩擦系数测量方法的研究是解决我国道面摩擦系数测量工作的重要任务。提出一种基于有限元的道面摩擦系数测量方法,利用ABAQUS进行轮—路相互作用的多物理场耦合分析,分别获得不同载荷、气压和速度工况下摩擦系数与胎面摩擦(剪)应力之间的关系。通过分析获得单变量工况与多变量工况下摩擦应力的变化趋势,然后利用拟合法逆向求解摩擦系数,建立不同工况的摩擦系数估算模型,实现在特定工况下仅依靠胎面摩擦应力估算摩擦系数的测量方法。最后,采用机场跑道摩擦系数测试车对标准工况下的估算模型进行验证。6次测试距离为3000 m的实验结果表明,估算测量与实际测量之间的误差为2.47%~4.13%,通过实验验证了基于有限元法所构建的估算模型的有效性与准确性,为道面摩擦系数测量方法的研究提供思路。
With the rapid development of China’s civil aviation industry,the safety of aircraft takeoff and landing is an important consideration and challenge faced by the airport authorities.Friction,which is generated on the contact surface between the tire and runway,is a crucial factor in ensuring the safe landing of aircraft.Measuring the friction coefficient is a vital task for resolving the issue of measuring runway friction coefficient in China.In this paper,we present a finite element method to quantify the runway friction coefficient.We perform a multi-physical field coupling analysis of tire-runway interactions utilizing ABAQUS.This allows us to obtain the correlation between the friction coefficient and the tread friction(shear)stress under varying load,pressure,and speed conditions.By analyzing the trend of friction stress variation under both univariate and multivariate operating conditions,and subsequently employing the fitting method to reverse solve the friction coefficient,it is possible to establish models for estimating the friction coefficient under differing operating conditions.This leads us to the achievement of a measurement method that solely relies on tread friction stress to assess friction coefficient within specific operating conditions.Finally,a tester for determining the friction coefficient of airport runways has been employed to validate an estimation model in accordance with standard working conditions.Six experiments were conducted at a distance of 3000 metres,as a result,the discrepancies between the estimation outcomes and the actual measurements ranged from 2.47%to 4.13%.This study affirms the validity and accuracy of the finite element method-based estimation model and presents a stimulating framework for investigating the measurement technique of runway friction coefficient.
