液压挖掘机三维虚拟实验设备的设计与开发

摘要

The virtual prototype model of the hydraulic excavator is set up based on RecurDyn software, the work device modeling and kinematics simulation are carried out, the scope of its work is simulated and the best action state is obtained.Its 3D virtual labora-tory equipment platform is set up based on the virtual reality software Virtools and according to its different work conditions, a vivid and lifelike immersion learning environment of its structure and theory is provided.%基于多体动力学分析软件RecurDyn建立液压挖掘机虚拟样机模型，进行工作装置建模和运动仿真分析，并对液压挖掘机的作业范围进行动态仿真，得到挖掘机工作时的最佳作用状态。基于虚拟现实软件Virtools建立液压挖掘机三维虚拟实验平台，对液压挖掘机的不同工作状态进行虚拟模拟，提供液压挖掘机结构和原理的生动、逼真的沉浸式的学习环境。
