基于ADAMS的抓斗挖泥船转台结构动力学分析

摘要

以18 m3抓斗挖泥机为研究对象,运用动力学理论以及相关的动态仿真软件,通过建立挖泥机的刚柔耦合模型来模拟计算获得工作过程中转台结构的危险节点分布情况,以及危险节点的动态应力时间历程,为设备检测和结构的轻量化设计与结构优化提供参考.%With a 18 m3 grab dredger as the study object , a rigid-flexible coupling model is developed for the dredger using the kinetic theory and related dynamic simulation software to simulate the distribution of dangerous nodes of the turn -table structure during operation and the dynamic stress time history for dangerous nodes , providing reference for equipment detection, lightweight design of the structure , and structural optimization .
