Abstract

The invention provides a welding-based virtual production manufacturing method and system. The method includes the steps of according to a base material of each welding joint in a to-be-produced product and thermophysical performance parameters corresponding to a preset welding material, conducting elastoplasticity calculation, deformation analysis and stress analysis on each welding joint, and obtaining welding parameters and a welding sequence of the welding joints; according to the welding parameters of each welding joint, obtaining a three-dimensional process model and three-dimensional process equipment of the to-be-produced product; according to the three-dimensional process model, the three-dimensional process equipment and the welding sequence of the to-be-produced product, generating a welding process model of the to-be-produced product on the basis of three-dimensional offline programming, and adjusting each process in the welding process model; according to the adjusted welding process model, conducting virtual production manufacturing on the to-be-produced product. Manpower and material resources are reduced, and the production cycle of the to-be-produced product is shortened.

Description

technical field [0001] The invention belongs to the technical field of computer simulation, and more specifically relates to a welding-based virtual manufacturing method and system. Background technique [0002] With the diversification of product demand, product structure design has shown explosive growth. The trial production cycle from new products to mass production is long, and design feedback optimization is delayed accordingly. In the face of fierce market competition, the shorter the manufacturing cycle from design to production, the more cost-effective it can be, and the easier it is to open up the sales market. [0003] In the process of product testing or production, it is necessary to occupy the on-site workbench for manufacturing testing of new products. The traditional layout design uses an approximate structure for statistical estimation, and iteratively revises after the process layout is completed to optimize the process flow. On the one hand, it increase...
