装配工装是飞机制造过程中最重要的工艺装备之一,结构复杂,对刚度、强度和轻量化要求较高。使用有限元法对某型飞机进气道后段装配工装进行仿真分析和优化设计,针对装配工装的复杂性提出离散化模型简化原则和参数化优化方法,直观、显著地提高了工装骨架的刚度,最大形变量优化为0.071 5 mm,且保证其不过于笨重,节约了原材料的使用量。
Assembly tooling is one of the most important process equipment in the aircraft manufacturing process. Its structure is complex and its rigidity, strength and light weight requirements are high. The finite element method is used to simulate and optimize the design of the assembly tooling of the rear air intake of a certain aircraft. According to the complexity of assembling tooling, the simplified principle and parametric optimization method of discretization model are proposed. The rigidity of the skeleton of tooling is significantly improved , The maximum deformation variables optimized to 0.071 5 mm, and to ensure that it is not too bulky, saving the use of raw materials.
