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.

Key words： inerter ISD suspension seat human vibration parameter identification;performance analysis
