8t液压挖掘机工作装置的运动仿真
|
摘要
使用Creo2.0软件对挖掘机工作装置进行三维建模,基于动力学分析软件ADAMS2016建立虚拟样机,并进行运动仿真,设计相关的step函数,实现挖掘机工作装置某些特殊工况,进一步得出整个工作装置的轨迹包络图,从而获得一些重要工作参数如最大挖掘半径、最大挖掘深度、最大卸载高度等.同时建立工作装置的数学模型,并通过MATLAB软件进行编程计算,来探索挖掘机的工作性能及运动规律.仿真所得的数据可以为后期优化改进提供理论依据和设计参考.
Creo2.0 software is used to build the three-dimensional model of excavator working device.Based on ADAMS2016 software,the virtual prototype is built,and the motion simulation is carried out.The step function is designed to realize some special working conditions and obtain the trajectory envelope diagram of the whole working device.Some working parameters are obtained,such as maximum excavation radius,maximum excavation depth,maximum unloading height and so on.At the same time,the mathematical model of the working device is established,and the program calculation is carried out by MATLAB software to explore the working performance and movement rules of excavator.The simulation data can provide theoretical basis and design reference for later optimization and improvement.
