Research on Estimation Method of Wire Harness Outer Diameter

As the organic interconnection carrier of complex products, electrical network transmits power supply, control signal and data information for each system, and its reliability is an important prerequisite for product performance assurance. In the process of installing and fixing the wire harness of the network, the clamp is usually used as the main support, and the selection of the clamp is mainly based on the outside diameter (diameter) of the wire harness segment. In addition, the diameter of the wiring harness and its segment has guiding significance for the design of the wiring harness path and the size of the mouth frame, so it is very important to estimate the outer diameter accurately. Based on the structure characteristics of wire harness, this paper puts forward a method of wire harness outer diameter simulation calculation, and proves the advantages and disadvantages of this method compared with the traditional outer diameter estimation method, and verifies its engineering application value.
