摘要
对整车汽车衡基础进行分块预制然后运到现场安装,可以有效降低整车汽车衡施工与安装周期,满足运输和吊装的可行性,相邻分块基础之间通过内置预埋件焊接进行连接,满足连接的便捷性和可靠性要求。为检验设计方案是否满足强度要求,通过有限元方法对整车汽车衡在检定时的满载荷工况进行分析,对混凝土承载基础、钢筋和焊接钢板进行结构强度分析,结果表明混凝土和焊接钢板最大应力均小于其屈服强度值。最后对分析结果中出现应力较大的地方提出改进建议。
To effectively reduce the construction and installation cycle of the truck scale,the whole truck scale foundation can be prefabricated and transported to the field for its installation.It meets the feasibility of the transportation and hoisting.The adjacent sub-blocks are connected by welding embedded parts,it meets the convenience and reliability requirements of the connection.In order to check whether the design scheme meets the strength requirement,the full load condition of the vehicle scale is analyzed by finite element method,and the structural strength of the concrete bearing foundation,steel bar and welded steel plate is analyzed.The results show that the maximum stress of the concrete and the welded steel plate is less than the yield strength.Then,the suggestions for improvement are made on the areas where the stress is greater in the analysis results.
