摘　　要：路基箱是大型履带式起重机的重要配件,为了保障其安全工作,应当使用合理的计算模型对其进行力学性能分析。利用ANSYS软件分析了路基箱常用的三种计算模型,通过计算结果与试验数据的比较,说明了它们各自的优缺点,并给出不同计算模型具体的使用条件,供结构设计人员参考。As an indispensable accessory,welded grillage slabs should be analyzed with a reasonable and practical calculation model to guarantee the safe operation.Three kinds of regular calculation model of welded grillage slabs were analyzed using ANSYS program,and the respective advantages and disadvantages were described in detail by comparing calculation results and experimental data.Their specific using conditions were given for engineering practice.
