将铰点力等效到铰孔边缘的５个节点上，建立了ＣＡＴ９８０Ｓ装载机前车架、动臂有限元计算模型。采用ＳｕｐｅｒＳＡＰ９１有限元分析程序计算了前车架、动臂各工况下的应力，分析了其受力情况，并将计算值与试验值进行了比较。
The hinge force is equivalent to the five nodes on the edge of the reaming hole, and the CAT980S loader front frame and boom finite element calculation model are established. The stress of the front frame and the boom under each working condition was calculated by SuperSAP91 finite element analysis program. The stress situation was analyzed and the calculated value was compared with the test value.
