Optimization Design of Customized Passenger Car Cockpit Layout based on Safety Ergonomic Principles

摘要

The optimization design problem of customized passenger car cockpits layout is increasingly complex and of growing interest in the Chinese car market. A new system is proposed to solve this problem based on ergonomic principles. Firstly, based on Kendall's W, groups and optimization sequences of facilities are determined using a combination of Delphi and the analytic hierarchy process. Secondly, the degree of crowdedness in the cockpit layout can be controlled by users' preference. Thirdly, a particle swarm optimization (PSO) algorithm is adapted to three-dimensional car cockpit layout optimization, and the resulting inertia-adaptive PSO is compared with some typical algorithms to show superiority. Finally, the results are reasonably analyzed in ergonomic simulation software. Thus, the proposed platform is demonstrated to be feasible and effective.
