Abstract: At present, the terminal crimping height of the new energy vehicle harness is determined by means of test and verification in the industry, without involving a pre-planning system for the terminal crimping scheme, this system can calculate the terminal crimping scheme quickly and accurately before the start of production, so as to promote the process of production smoothly. This paper introduces the theoretical calculation method, database creation, user interface and the design and implementation of the calculation system for the terminal crimping height of the new energy vehicle wiring harness, and is verified by the comparison between the theoretical calculation and the practice, the two conclusions are the same, which can provide scientific reference and guidance for the scheme of wire beam terminal crimping.
