摘　　要：基于COSMOSWorks有限元分析平台,建立了多功能车提升架的有限元模型,通过提取恶劣工况下提升架的动态极限载荷,完成了提升架的动强度研究,获得了提升架应力场分布云图,确定了提升架受力的最危险位置;通过改进,提升架危险部位的强度提高了20%,分析结果表明,提升架的动强度和刚度可以满足实际工作需要,保证了提升架的可靠性。Based on COSMOSWorks fiat of finite element analysis,the finite element model of hoisting frame on multi-purpose vehicle was established. By extracting dynamic loads of hoisting frame under its worst work condition, the dynamic strength of frame was dangerous position was confirmed. By improving form researched. The stress field was acquired and of frame,the dynamic strength of frame was enhanced about 20%. The analysis result indicates that dynamic strength and stiffness can satisfy work condition of hoisting frame, and reliability of frame is guaranteed.
