摘要
将德国制造的 30t/ 76 2m∏型桁架式装卸桥简化为空间桁梁混合结构模型 ,利用有限元法对其进行动态特性分析 ,计算结果与测试结果非常接近。从测试数据也说明 ,桁架式装卸桥属于小阻尼振动系统。
In this article,the 30t/76 2m ∏ shape lattice structure transporter crane made in Germany is simplified as a space bar beam model.Analysis of the dynamic characteristics for this model is perfomed by use of finite element analysis method.The result is very close to the actually measured value.Lattice Structure transporter crane is a vibration system featuring a small damping factor,which has been proved by the actually of the dynamic characteristics and calculation of the dynamic response for other lattice structure gantry cranes and transporter cranes.
