基于动作元的汽车离合器操纵舒适性的优化

摘要

In view of the difficulty in evaluating quantitatively the operating comfort of vehicle hydraulic clutch, first of all, according to the mapping relation between human motions and the various design factors of operating device, a concept model of motion elements is introduced.The motion element matrix is used to describe the operation process of hydraulic clutch, and the operating comfort of hydraulic clutch is measured by the proximity coefficient between practical motion element matrix and design target matrix.Then, based on the analysis on the working principle of hydraulic clutch, a mathematical model and an optimization model for operating comfort of vehicle hydraulic dutch are established and an optimization is conducted.Finally, the feasibility of this method is validated by a real example.%针对实际设计过程中难以定量地评定离合器操纵舒适性等问题,首先根据操纵装置各种设计因素与人体动作的映射关系,引入动作元概念模型,并采用动作元矩阵来描述汽车离合器操纵过程,通过实际动作元矩阵与设计目标矩阵的贴近度来衡量离合器的操纵舒适性程度;然后,在对液压式离合器工作原理进行分析的基础上,建立汽车液压式离合器操纵舒适性的数学模型和优化模型,并进行优化;最后,通过实例验证该方法的可行性.
