摘要: |
针对目前导弹零部件容差设计主要依赖经验,实际装配时极易发生干涉的问题,以某型号导弹舱段为例,基于3DCS软件开展了其装配容差分析与优化研究。首先在掌握实际装配工艺的基础上,简化建立了其尺寸链方程;然后基于3DCS软件建立了其装配过程容差分析模型,找出并改进了其设计的不合理处,避免了实际装配出现问题。 |

Abstract: |
Aiming at the problem that the tolerance design of missile parts mainly depends on experience, and it is easy to interfere in actual assembly, taking a certain missile cabin as an example, the assembly tolerance analysis and optimization research are carried out based on 3DCS software. Firstly, on the basis of mastering the actual assembly process, the dimension chain equation is simplified; secondly, the tolerance analysis model of the assembly process is established based on 3DCS software to find out the unreasonable parts of the design, and improve it, so as to avoid the problems in the actual assembly. |
