Description

Fast Wire Harness Principle Simulation Analysis Method technical field The invention belongs to the technical field of automobile simulation analysis, in particular to a kind of fast wire harness principle simulation analysis method. Background technique The traditional automobile wiring harness design is to directly draw the wiring harness product on the 2D drawing through manual calculation and checking. Size, connector type, wrapping type, wire loop continuity and other information, the electrical principle information is provided by the wiring harness design engineer Manual control, the correctness, standardization and integrity of drawings are greatly affected by the design experience value of engineers, and the degree of automation is low. For the electrical configuration requirements of different models, the traditional 2D drawings have low usability, and a large number of design workers are required for different electrical configurations. It is repeated and ...

Problems solved by technology

[0004] At present, the principle simulation of automotive electrical appliances is mainly divided into two directions: the refinement of the electrical model (to accurately simulate the real situation) and the simplification of the electrical model (to quickly complete the function inspection). The analysis of the specific cause of the problem, but due to the long calculation time, it is not suitable for the comprehensive inspection of the auxiliary design; the quick completion of the function inspection is mainly divided into two aspects: the global function inspection and the partial function inspection. The number of times is increasing exponentially, which is difficult to meet the needs of rapid development and design, and partial function inspection is affected by the experience of design engineers, often not considered comprehensively, and it is easy to miss functions that are not checked
