摘　　要：对物料冲击漏斗全过程进行瞬态动力学分析,对冲击载荷及带斗门机动态特性进行分析计算,运用数值仿真技术得到其位移响应表达式及位移响应曲线,为结构优化设计和带斗门机动力学分析提供理论依据。The transient dynamics analysis subjected to the material impact on the funnel in the entire process and then the computation to the impacting load as well as the dynamic characteristic on the portal crane with self - funnel are carried out. The obtained displacement response expression and its response curve by using the digital simulating technique can be as theoretical reference for the structural optimal design and the dynamic analysis to this kind of crane.
