Method for constructing model base based on reverse engineering

Abstract

The invention discloses a method for constructing a model base based on reverse engineering. The method comprises the steps of using an ADAMS to establish a dynamical model of a mechanical structure, and obtaining an ADAMS hardpoint file; reading coordinate values of each hardpoint in the ADAMS hardpoint file, and forming a revisable hardpoint table; according to the hardpoint table, establishing a hardpoint mechanical structure model; according to the hardpoint mechanical structure model, establishing a mechanical structure point and line model of each component of the mechanical structure; designing detailed digital analogy of the component according to the mechanical structure point and line model of the component; optimizing the detailed digital analogy; establishing a mechanical structure point and line DMU model, decorating the optimized detailed digital analogy of each component to a corresponding point and line component, and obtaining a parameterized DMU model of the mechanical structure. According to the method, through the use of the reverse engineering, the workload needed for design alternation in the mechanical structure design process can be reduced, and an optimized mechanical model is obtained.

Description

technical field [0001] The invention relates to the field of model library construction design, in particular to a method for constructing a model library based on reverse engineering. Background technique [0002] At present, when mechanical engineers construct the mechanical model library, they first select the mechanical structure form according to the mechanical requirements, and determine the performance parameters of ride comfort and stability. Then use software such as ADAMS (Automatic Analysis of Mechanical Structural Mechanics) to establish a suspension dynamic model, and continuously adjust the hard point (Hardpoint) to make each performance parameter reach the expected value. Among them, the design hard point is the general term for the control points or coordinates, control lines, control surfaces and control structures determined in order to ensure the coordination and assembly relationship between parts and components and the styling style requirements during t...
