[Abstract]:The aircraft assembly process route is long, the type and quantity of the process equipment used are various, and there are many links to produce errors. Reasonable tolerance analysis and optimization techniques are of great significance to ensure the interchange and coordination of aircraft components structure. The aim of this paper is to establish a systematic and perfect tolerance design method for aircraft components. Based on the carding and optimization of the assembly process of typical parts of aircraft, this paper simplifies and normalizes the typical assembly process of single station. The key features of assembly quality are defined and the tolerance optimization algorithm is studied around the corresponding software tools. The main contents of this paper are as follows: 1: 1. In this paper, the assembly process of aircraft is deeply analyzed, and the assembly process of four kinds of typical structural parts is established. The mechanical processes of positioning, clamping, connecting and springback are simplified, and the key characteristics and deviation control methods for controlling assembly quality are defined. This paper puts forward three principles for making assembly process plan, standardizes the modeling method and procedure of single station assembly deviation analysis, and lays a foundation for assembly deviation modeling. This paper systematically studies the process and method of solving the assembly deviation model and the tolerance analysis of aircraft complex parts by using VSA and 3DCS software. The problems such as how to select the tolerance adjustment object and how to judge the rationality of the new tolerance distribution scheme are discussed. The principle of maximum sensitivity priority modification is put forward, and the iterative method of tolerance optimization is analyzed. Taking a certain type of external flaps and boarding gate components as an example, the corresponding assembly process scheme is determined by using the above establishment methods and principles. The tolerance modeling, tolerance analysis and optimization are studied with VSA and 3DCS software tools. The structural analysis, process scheme formulation, tolerance analysis, tolerance optimization and equal tolerance analysis and optimization of aircraft components assembly are systematically studied.
