SAWE Paper No. 3469 - COMPARISON OF POWER DISTRIBUTION SYSTEMS FOR LAND VEHICLES

摘要

For combat vehicles, power distribution systems face a multitude of challenges caused by shrinking space availability, demanding thermal environments, reliability constraints, and the need to reduce system weight. This paper investigates the trade between two different design methodologies: cable conductors and bus bar concepts. The design approach and thermal assessments are investigated to achieve a weight optimized solution for high powered applications. In this study, a 2D Computation Fluid Dynamic (CFD) model is created to simulate the natural convection and conduction cooling of the cable conductor and a laminated bus structure.
