摘　　要：通过对运梁车的受力特点分析,以建立接触、连接副的方式,较真实的模拟了驮梁小车与车架之间的相互作用,建立了运梁车车架的有限元计算模型,获得了车架的应力分布,为该车的结构设计与改进提供了理论依据。Truck frame is the main loaded part of beam carrier, according to the analysis on structural features of beam carrierr, the interaction between trolley and truck frame is simulated more truly by establishing contact and connection. The FEM model of beam carrier frame is simulated more truly, by establishing contact and connection. The FEM model of beam carrier frame is established, and the stress distribution of truck frame is obtained, which provides a theoretical basis for rational design and refinement.
