为掌握伸缩臂叉装车翻车保护结构(ROPS)的设计方法,利用ANSYS软件的材料非线性有限元仿真模块,针对其侧向加载的试验过程进行多次仿真,根据仿真结果不断改进ROPS结构,使其侧向作用力和侧向载荷能量的最小值同时满足国际标准要求。对于设计的ROPS,进行实物侧向加载试验,试验数据与仿真结果基本吻合,结论证明提出的RO P S侧向加载仿真方法合理,可避免RO P S实物的反复试验,有利于更好地掌握RO P S设计规律。
In order to grasp the design method of overturning protection structure (ROPS) of telescopic forklift, by using nonlinear finite element simulation module of material of ANSYS software, several simulations were carried out for the test process of lateral loading, and the ROPS structure was continuously improved according to the simulation results. So that the minimum lateral force and lateral load energy at the same time meet the requirements of international standards. For the design of the ROPS, the physical lateral loading test, the experimental data and the simulation results are basically consistent conclusions proving RO PS side loading simulation method is reasonable, to avoid RO PS physical test, is conducive to better grasp of the RO PS Design rules.
