Abstract: With the continuous advancement of electrification and intelligence,the wiring harnesses in products such as aircraft and automobiles have become increasingly numerous and complex,making their layout and installation more challenging.Nume-rous wiring harnesses are installed through a series of convergence points known as clamps,where a single harness may pass through multiple convergence points,and a single convergence point may contain multiple harnesses.If the layout of the wiring harness within the convergence point is not reasonable,it may lead to problems such as crossing and twisting between the wiring harnesses,which does not meet the requirements for smoothness of the wiring harness.Currently,engineers mainly manually adjust the layout of harnesses within convergence points based on experience.However,due to the large number of convergence points and their mutual influence,manual adjustment is not only labor-intensive but also difficult to achieve optimal results.To address this issue,this paper proposes a smoothness-oriented collaborative wiring harness layout algorithm in convergence points.The method firstly transforms the wiring harness layout within multiple convergence points into a set of optimization problems,obtaining a preliminary layout that meets the smoothness requirements through optimization solving.It mathematically models the wiring harness smoothness problem and uses optimization algorithms to obtain the layout of the harnesses within all convergence points,ensuring the smoothness of the harnesses.Then,a compact algorithm for ensuring the layout of the wiring harness is proposed,which maintains the smoothness of the wiring harness and compactly arranges the wiring harness within the convergence point to save installation space and increase the stability of the wiring harness.The proposed algorithm has been applied to the products of our partners,and through the testing of synthetic and actual cases,the results demonstrate the effectiveness of the method.
