摘要
针对虚拟路面构建方法的重要环节载荷预估,总结适用于多体动力学软件的比利时石块虚拟路面的3种建模方法.为充分对比各方法的计算效率,编写实现可生成任意路径的RDF格式比利时石块虚拟路面的程序,并与规则栅格路面(Regular Grid Road,RGR)格式及曲线规则栅格路面(Curved Regular Grid,CRG)格式进行对比.结果表明:在计算效率及适用性方面,RGR和CRG格式路面优势更为明显;RGR格式路面的动态载入技术和CRG格式路面的横向间距可变特性,使其更适用于建立比利时石块虚拟路面.
The load prediction is an important procedure for the building method of virtual road. Three different modeling methods are summarized for multi-body dynamic software that is adaptive to the virtual Belgian block road. To compare the calculation efficiency of these methods fully, a program is developed which can generate RDF files of virtual Belgian block road of arbitrary centerline, which are compared with Regular Grid Road （RGR） format and Curved Regular Grid （CRG） format. The results indicate that, the RGR format and the CRG format are more advantageous both in calculation efficiency and scope of application; the dynamic loading technology of RGR format and the character of non-equidistant space in transverse direction of CRG format make them more suitable to generate virtual Belgian block road.
