中文摘要：

驾驶员腰部的肌肉力、关节力等负载与驾驶舒适性密切相关,但难以直接测量。本文中建立了驾驶员肌肉骨骼生物力学模型,提出了一种基于Matlab-OpenSim联合仿真的驾驶员与座椅界面接触力和摩擦力计算求解方法,并通过人椅接触压力测试和接触界面摩擦力与腰椎关节压力仿真对上述模型和方法进行验证。结果表明,本文中提出的驾驶员肌肉骨骼生物力学模型和人椅界面接触负载的计算方法可有效解决行驶工况下驾驶员腰部负载的定量评估问题,对驾驶室空间布局和舒适性设计具有重要工程应用价值。

英文摘要：

The muscle forces and joint forces of driver＇s lumbar are closely related to driving comfort,but are difficult to measure. In this paper,a musculoskeletal biomechanical model of driver is created,a calculation method of contact force and friction force on driver-seat interface is proposed based on Matlab-Open Sim co-simulation,and the above-mentioned model and methods are verified by the measurement of contact pressure between driver and seat and the simulation of the friction force on contact interface and the pressure on lumber vertebra joint.The results show that the model created and the methods proposed can effectively tackle the issue of quantitative evaluation of the lumbar loading of driver in driving condition. This study has a high engineering application value for the spatial layout and comfort design of car cabin.
