This paper studied the dynamic process of a dual-trolley overhead crane transshipping rigid-body cargo with degrees of spatial freedom. By taking the tensile stiffness of wire rope, the bending stiffness of box girder and the mass of cargo as variables, six different working conditions were calculated. The influences of the variables on spatial movement of slender cargo were analyzed. To verify the presented analytic model, a virtual prototype model was constructed by using the commercial software ADAMS and ANSYS. The consistency of the calculation results from the two different models proves the effectiveness of the analytic model presented in this paper.

结构弹性对双小车桥式起重机转运动力学的影响

研究了具有空间自由度的双小车桥式起重机转运刚体货物的动力过程。以钢丝绳抗拉刚度、箱梁抗弯刚度和货物质量为变量，计算出6种不同工况。分析了变量对细长货物空间运动的影响。为了验证所提出的解析模型，使用商业软件ADAMS和ANSYS构建了一个虚拟原型模型。两种不同模型计算结果的一致性证明了本文提出的解析模型的有效性。
