Crashworthiness analysis and mu lti-objective opti mization of multi-cell tube for high-speed train
摘要
Abstract
To design the energy-absorbing structure of high-speed train,based on the principle of multi corner and multi cell,three thin-walled tubes with different cross-sectional shapes were proposed and analyzed numeri-cally;meanwhile,conventional square tube was also analyzed for comparison.The results show that T4 tube has better performance in energy absorption.Then,the multi-objective optimization for T4 tube was conducted to a-chieve maximum specific energy absorption and minimum peak crushing force.The pareto frontier was obtained. Using the optimization result,the difference between the optimized tube and original tube was small,which means the original design is a good choice.关键词
