摘　　要：基于DELMIA平台,提出一种飞机大部件调姿、对接等装配过程的系统仿真方法。在分析了装配整体流程和需求后,针对并联机构、运动过程、干涉分析等仿真难点问题分别进行了研究:提出了一种多POGO柱并联调姿系统的设计方法,可以仿真多POGO柱以及工件的联动;利用DELMIA中的Tag点及示教功能,实现了运输、入位、调姿、对接等过程的仿真;在系统中加入测量系统和产品的干涉检查模块,能够对装配全程可能发生的碰撞和激光跟踪仪光线遮挡情况进行检测。最后,通过对某型号飞机总装过程进行仿真,验证了本方法的有效性。Based on the platform of DELMIA,a system simulation method for posture alignment and docking of aircraft large parts is proposed.After analyzing the overall assembly process and requirements,the difficulties such as simulation of parallel mechanism,motion process and interference analysis are studied:a design scheme of parallel posture alignment system with multi POGO sticks is proposed,which can simulate the united movement of multi POGO sticks and workpiece;the simulation of transportation,positioning,posture alignment,docking and other processes is realized by using Tag points and teaching functions in DELMIA;interference inspection of measurement system and product is added,which can detect the possible collision and light occlusion of laser tracker during the assembly process.Finally,the assembly process of a certain type of aircraft is simulated to verify the effectiveness of this method.
