摘要/Abstract

摘要： 为解决虚拟装配存在人机交互度、行为仿真与用户设计效果不佳等问题。以大型拖拉机变速箱为对象,研究了多碰撞体的齿轮动力学运动与行为仿真方法,提出了基于轴和面约束的多零件模型在虚拟环境中的定位方法,开发了人机交互式的虚拟环境,每帧消耗的时间约为10 ms,实现了复杂变速运动行为及其仿真。同时虚拟装配模块里配置了AR接口,可通过手式进行主动式智能虚拟装配。试验表明,系统能按照用户需求进行主动式的虚拟装配、干涉检测、学习装配知识、方案设计、提示装配错误等,为复杂变速箱的虚拟制造与装配提供了仿真平台,平台具有可扩展性。

Abstract: Aiming at the human-computer interaction, behavior simulation and user design in virtual assembly, based on the complex gearbox of large tractors, the simulation method of dynamic motion and behavior of gear with multi-collision body is studied. The positioning method of multi-part model based on axis constraints and surface constraints in virtual environment is proposed. The virtual environment of human-computer interaction is developed. The consumed time of per frame is about 10 ms, and the complex variable-speed motion behavior and its simulation are realized. The virtual assembly system is equipped with AR interface, which can realize the active intelligent virtual assembly by hand. The experiments show that the system can provide active virtual assembly, interference detection, assembly knowledge learning, program design, and assembly error messages of the user requirements. It provides a simulation scalable platform for virtual manufacturing and assembly of complex gearboxes.

Key words: virtual reality, gearbox, motion simulation, virtual assembly, collision detection
