Design and manufacturing method of a rail vehicle electrical wiring harness

Abstract

A designing and manufacturing method for electrical harnesses of a rail vehicle. The main object thereof is to solve the existing problems and disadvantages in a designing and manufacturing process of electrical harnesses of a rail vehicle, and to provide a designing and manufacturing method suitable for electrical harnesses of a rail transport vehicle which can effectively standardize and improve the standard and quality of electrical circuit construction, and improve the efficiency of research and development and production by performing module division on electrical harnesses of a vehicle and respectively designing and manufacturing different harness modules according to basic information about the rail vehicle.

Description

technical field [0001] The invention relates to a design and manufacturing method of an electrical wiring harness, in particular to a design and manufacturing method of an electrical wiring harness of a rail transit vehicle. Background technique [0002] Existing rail transit vehicles mainly include different series of vehicles such as EMUs, urban rail vehicles, railway passenger cars, and light rail vehicles. There are certain differences in electrical systems and structures. The configuration from the structure to the electrical system has certain commonalities, but there are also certain differences. Taking the 8-carriage high-speed rail or bullet train commonly used as an example, from the perspective of car marshalling and structural layout: there are drivers at both ends According to different functions, there are first-class cars, second-class cars, dining cars, cars with pantographs, cars with toilets, cars with mechanic’s room, etc.; from the perspective of equipmen...

AI Technical Summary

Problems solved by technology

Therefore, the electrical settings of each car will be different. The electrical design of various models is usually carried out separately for each model. Therefore, there are also large differences in the design and production of electrical harnesses. There are electrical harness wiring designs and The construction standards are not uniform, and the construction quality is unstable. Moreover, if the design of the electrical wiring harness and the supporting manufacturing method are carried out separately for different structures of the car body, it will be time-consuming and labor-intensive, affecting the progress of R&D and production, and cannot form an effective R&D inheritance.
