The simulation of cable harness based on mass-spring model

Abstract

The simulation of cable harnesses is challenging due to the complex structure and the large deformation during the assembly operations. In this paper an improved mass-spring model is approached to simulate the shape of cable harnesses and to calculate the deformation of cable harnesses. Based on a virtual software platform Open Cascade and using Newmark-â algorithm which could reduce the instabilities of equation, the simulation is completed. Then, a cable geometry measurement bench with the 3D laser scan technology is construed to verify the accuracy of the algorithm. The result shows the model could simulate the deformation very well.
