摘　　要：针对全断面掘进机的关键部件设计理论不够完善、制造工艺不够合理等问题,在设计阶段采用数字样机技术对其进行动态仿真。通过对刀盘系统和管片拼装机进行运动学和动力学仿真,在数字样机上分析其运动规律、进行机构干涉检查以及评估驱动力和扭矩大小,为不同地质条件下的刀具布置和选型提供参考。采用基于数字样机技术的有限元方法进行模态和强度仿真分析,获得关键部件的各阶振型图和应力变化规律,为关键部件的动态优化设计提供依据。Aiming at the problems of the lack of perfect design theory and reasonable manufacture technology of key components in tunnel boring machine, virtual prototype technology was used to simulate dynamically in design process. The motion law, interference detection of mechanism and evaluation of drive force and torque were analyzed based on digital prototype, by kinematic/dynamic simulation of cutter system and segment erector, which provided an reference to cutters layout and selection in different geological conditions. The vibration shape and the stress variation law of key components were obtained by the simulation analysis of mode and strength based on FEM of digital prototype technology, and provided foundations for dynamic optimal design.
