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。
Driver’s waist muscle strength, joint force and other loads and driving comfort are closely related, but difficult to measure directly. In this paper, the driver’s musculoskeletal biomechanics model was established, and a method to calculate the contact force and friction force between the driver and the seat based on the Matlab-OpenSim co-simulation was proposed. Through the contact pressure test and contact friction And lumbar joint pressure simulation of these models and methods to verify. The results show that the musculoskeletal biomechanics model proposed in this paper and the calculation method of the contact load between the human and the chair can effectively solve the quantitative assessment of the driver’s waist load under driving conditions and are important for the cab layout and comfort design Engineering application value.
