Current Trends in Automotive Wire Harness Design（目前的趋势在汽车线束设计）.pdf

International Conference on Mechanical, Production and Automobile Engineering (ICMPAE2011) Pattaya Dec. 2011 Current Trends in Automotive Wire Harness Design Mr. Ajay Pradhan Abstract—Wire Harness is the interconnecting wiring in the III. BACKGROUND DETAIL vehicle for the transmitting electrical power and signals in the electrical system. Over the years the number of components to be A. Principles Of Wireharness Design connected and hence the number of circuits has increased many The wire harness design is usually last component to be folds. This has made the wire-harness design as the most complicated finalized on the vehicle proto-type. Various design changes task in the vehicle design and wire harness (electrical system ) integration with the other aggregates a difficult job. Many CAD tools are done to meet requirements of access, serviceability and and design software have evolved from computer companies. But robust design. But the inherent flexibility in the routing and they have not resolved major issues faced by vehicle OEM’s and the adaptability to other system items, results in the design of wire wire-harness manufacturers. In fact, the requirements of vehicle harness being changed to incorporate feedbacks from different manufacturers are not clear to the other agencies and this results in agencies. wire-harness development as a major bottleneck in any vehicle
