Abstract

The invention relates to a design method of a main-spring compression type low-frequency vibration-isolation vehicle seat shock-absorber damping coefficient and belongs to the technical field of vehicle seats with an aim to solve problems that previous design methods of the main-spring compression type low-frequency vibration-isolation vehicle seat shock-absorber damping coefficient are not reliable and a design method adopting 'experience with repeated trials' cannot meet requirements of modern CAD (computer-aided design) design and rapid development of the vehicle seats. With the method provided, the shock-absorber damping coefficient can be designed rapidly, accurately and reliably according to structure parameters, crew quality and vehicle driving traffic of the main-spring compression type low-frequency vibration-isolation vehicle seats, and the shortcoming of repeated trials in the traditional design methods is avoided; with the method, design level and quality and vibration-isolation performance of the main-spring compression type low-frequency vibration-isolation vehicle seats can be improved, design and trial costs of the seats are reduced, design cycle is shortened, and seat development is sped up.

Description

technical field [0001] The invention relates to a vehicle seat, in particular to a design method for the damping coefficient of a main spring compression type low-frequency vibration-isolated vehicle seat shock absorber. Background technique [0002] As the last link to attenuate vehicle vibration, the seat plays a vital role in the comfort performance of the vehicle. In recent years, cervical spondylosis and digestive system diseases caused by low-frequency vibration have become common driving diseases for vehicle drivers and passengers. Therefore, improving the low-frequency vibration isolation performance of vehicle seats is of great significance to avoid impact damage to internal organs of the human body and the occurrence of driving diseases. The main spring compression type low frequency vibration isolation vehicle seat can be used to attenuate the low frequency vibration of the vehicle, and has gradually attracted people's attention. The damping coefficient of this ...
