| 摘 要： | 为了合理确定机场刚性道面设计中的动载系数,减少道面荷载现场测试的工作量,利用ADAMS软件进行仿真研究,分析了飞机着陆时道面的竖向荷载、纵向水平荷载和横向水平荷载的动态响应规律.通过改变飞机着陆时的俯仰角、滚转角、初始下降速率和初始机轮离地距离4个主要参数,分析道面受载情况的敏感性,并利用白噪声线性滤波法生成不同等级道面,研究了不同平整度下道面的动态响应规律.研究结果表明:初始下降速率从0 m/s增大到3 m/s时,动载系数从0.677增大到1.623;着陆水平荷载主要为纵向水平荷载;飞机对H级道面的动荷载最大值比A级道面增大68.71%.

| Abstract: | In order to provide a rational dynamic load coefficient for airport rigid pavement design and reduce the workload of the pavement dynamic load test,the software ADAMS was used to analyze the dynamic response mechanisms of the vertical load,longitudinal load,and lateral load on the pavement.The loading sensitivity of the pavement was analyzed by independently varying pitch angle,roll angle,initial descending rate,and initial ground clearance.In addition,different roughness levels of pavements were generated by the white noise linear filtering method to study the effect of roughness level on the dynamic load response of pavements.The results show that when the initial descending speed increases from 0 to 3 m/s,the dynamic load coefficient increases from 0.677 to 1.623;the horizontal load during aircraft landing is mainly in the longitudinal direction;and the peak value of aircraft dynamic load on level H pavement increases 68.71% than level A pavement. |
