Researches on vehicle crashworthiness are the frontier in the current vehicle passive safety field, which is very important for the improvement of road traffic safety. One of the most effective methods to improve the crashworthiness is to optimize the thin-walled tubular structure. The definition of vehicle crashworthiness and the structural optimization theories of thin-walled tubular components were first identified. Then, the development processes, methodologies and results for the structural optimization of thin-walled tubular components for crashworthiness were reviewed. Finally, the latest research direction of structural synthesis of thin-walled tubular components was proposed, comparison among different structural optimization methods were presented, and the development prospect of the structural optimization of thin-walled tubular components for crashworthiness was recommended.
