基于子系统原理的线束拓扑分析

Analysis of Wire Harness Topology Based on Subsystem Principle

文章以"三段式"整车线束分段策略和H型线束拓扑为案例,阐述了一种分析方法,通过子系统原理分析,将子系统中的电器件归类为子系统控制器和外围功能器件。其中,外围功能器件由人机、造型和功能决定,确定子系统的功能分配和实现方式,分析子系统控制器的位置变化对线束拓扑的回路长度、断面直径、线束对接接插件数目的影响,选出最优子系统控制器位置下的最优线束拓扑,并将各个最优子系统线束拓扑汇总成整车线束拓扑。

In this paper,the "three-section" harness segmentation strategy and H-shaped harness topology are taken as examples,and an analysis method based on subsystem principle is analyzed. The electrical components in the subsystem are classified into subsystem controllers and peripheral functional devices,and the peripheral functional devices are determined by human-machine,modeling and function. The function distribution and implementation of the subsystem are chosen,and the influence of the harness topology through the position change of the subsystem controller,including the loop length,section diameter and number of inline connectors are analyzed. The optimal harness topology under the optimal position of the subsystem controller is selected,and the vehicle wire harness topology through each subsystem of vehicle is summarized.
