摘　　要：针对航空发动机装配工作繁琐、易出错等问题,基于DELMIA数字化装配仿真平台,以某型航空发动机单元体装配为研究对象,进行装配工艺规划,在DPM模块中实现虚拟装配总成仿真,通过干涉碰撞检查分析,验证装配工艺设计的合理性。以高压压气机单元体与燃烧室单元体之间实际工位装配仿真为例,结合人机工程仿真技术,分析安装工人的视觉匹配度、肢体工作空间及姿势疲劳易感度,优化不合理的工艺姿势。仿真结果表明,采用虚拟装配技术对装配工艺进行验证可以提前发现并解决装配工艺存在的问题,提高装配效率,降低研制成本。Based on the DELMIA digital assembly simulation platform,taking the unit assembly of an aircraft engine as the research object,this paper makes a plan for the assembly process and realizes virtual assembly simulation in the DPM module in view of the onerous and error-prone problems of aircraft engine assembly.Through interference and collision detection,the rationality of assembly process design is verified.Taking the assembly simulation of the actual station between the element bodies of the high-pressure compressor and combustion chamber as an example,this paper analyzes the visual matching degree,limb workspace,and posture fatigue susceptibility of installation workers combined with the ergonomic simulation technology to optimize unreasonable process postures.According to the results,verifying the assembly process by using virtual assembly technology can find and solve the problems existing in the assembly process in advance,improve the assembly efficiency,and reduce the R&D cost.
