摘要
针对塔式起重机司机培训和考核效率低、成本高、安全性差等问题,提出一种基于虚拟现实技术的培训考核仿真系统。在Virtools软件平台上构建交互式三维视景仿真系统,模拟司机在真实塔式起重机上的培训和考核操作,研究起升钢丝绳的悬链线方程,结合Virtools软件的物理系统,实现对钢丝绳的柔性仿真,包括钢丝绳的悬链线表达和摆动仿真,依据考核标准,建立考核评价体系,加入碰撞检测功能,实现考核评价机制,自动完成考核评价。仿真结果表明,该系统能较好地体现物体运动与碰撞的真实性,具有较强的可操作性。
Based on virtual reality technology, a simulation system for training and checking tower crane driver is developed to solve the problem of low efficiency,high cost and poor safety when using a real tower crane. In Virtools, an interactive 3D visual working environment is built,where a driver can simulate visual tower crane＇ s operation with real operating feeling. The flexible simulation of wire rope is the key problem. By catenary theory, hoisting rope＇ s mathematics equation is built, and its flexible and swing simulation is studied with the physical functions provided by Virtools. According to relative standards and rules, automatic check and evaluation system is established, which is embed in this proposed simulation system. Simulation results show that this system can well reflect the authenticity of object motion and collision. And this system is excellent in operability.
