Abstract:

In order to design a better high-speed train seat and improve the passengers' ride comfort, aiming at the problem that the design standards for the domestic high-speed trains in biomechanics issues was not clearly defined, a human lumbar L1~L5 finite element model was established, and verified by the experiments and theory. The model was analyzed in static state and 350km/h high-speed train running dynamics environment. The static state and structure response of spine were calculated under the action of an external stimulus in order to provide the basis of the high-speed train seat ergonomic design and improve the passenger comfort.

Key words: high-speed train, lumbar;vibration environment;ergonomic

摘要：

为了设计出更好的高速列车座椅，提高乘客的乘坐舒适度，针对国内高速列车设计标准在生物力学方面缺乏明确规定的问题，建立了人体腰椎L1~L5的有限元模型，并对模型的合理性进行了实验和理论验证。对不同坐姿下的腰椎模型进行了静态和350km/h高速列车运行环境下的动力学分析，计算腰椎静态和外部激励作用下的结构响应情况，为高铁座椅的人机工程设计提供依据。
