摘要

为解决悬架座椅设计中降低固有频率和保证系统刚度之间的设计矛盾，进一步改善悬架座椅舒适性，将惯容器运用到悬架座椅系统中。建立了ISD悬架座椅模型，选出了最适合座椅的ISD结构，并结合三自由度坐姿人体模型（ISO 5982（2001）模型）建立了四自由度人-椅系统集中参数模型。根据座椅台架试验对悬架座椅参数和人体参数进行了识别。分析了模型在不同频段下的动态响应，惯质系数在不同频段激励下的取值，以及惯质系数对座椅舒适性的影响和惯质系数与阻尼的匹配关系。结果显示，将惯容器运用于悬架座椅能明显降低系统固有频率、改善座椅舒适性；惯容器、弹簧和阻尼器三者并联是最适合悬架座椅隔振的ISD结构，舒适性的改善程度和最优惯质系数取值都与激励特征有关。

Abstract

In order to solve the contradiction between the requirements of lowering the natural frequency and ensuring the stiffness of the system in the design of a suspension seat, and further improving the comfort of the suspension seat, an inerter was applied to the suspension seat system. Inerterspringdamper(ISD) suspension seat models were established, and the best ISD structure was selected. Combining with the three degrees of freedom human body model (ISO 5982—2001), a four degrees of freedom humanseat system was established. The seat bench test was carried out for the purpose of identifying the parameters of the suspension seat and the human model.The dynamic responses of the models under different excitations, the influence of inertance on the seat comfort and the matching relation between the inertance and damping were analyzed.The results show that the use of the inerter in the suspension seat can significantly reduce the natural frequency of the system and improve the comfort of the seat. The parallel structure of the inerter, the spring and the damper is the most suitable structure for the suspension seat. The degree of comfort improvement and the optimal value of the inertance are all related to the excitation characteristics.
