Method for quickly designing mechanical products based on virtual instruments and reverse engineering

Abstract

The invention relates to a method for quickly designing mechanical products based on virtual instruments and reverse engineering. The method comprises the following steps of: acquiring the point cloud data through a prototype product model at first, obtaining a prototype product curved surface model through utilizing an imageware software according to the obtained point cloud data, utilizing CATIA software to form a prototype product solid model of the curved surface model, using a parametrization design to obtain a new product solid model, analyzing and computing the new model through utilizing ANSYS software so as to obtain a new product model which satisfies requirements, and finally, storing the model into a database and quickly forming through a quick forming machine. The method consists of a prototype product model data acquiring part, a data processing, analyzing and managing part with a computation and analysis software and a quick forming part. The data acquiring part is an optical measuring instrument, data measurement and acquisition can be realized through scanning, and the point cloud data of the model can be obtained.

Description

technical field [0001] The invention relates to a rapid design method for mechanical products. Specifically, it is a rapid design method of mechanical products based on virtual instrument and reverse engineering. Background technique [0002] The innovative design of mechanical products is an inexhaustible driving force for the development of the machinery industry. However, for the traditional machinery industry, especially some small and medium-sized enterprises, they are faced with long new product development cycles and high investment costs. It is difficult to quickly adapt to the development needs of product upgrading, which affects the improvement of independent innovation capabilities of enterprises. Although there are many mechanical product development software on the market at present, the functions are scattered, which is not convenient for developers to operate and use. Moreover, there is a lack of a complete management system for the developed new product inf...
