Abstract

The invention relates to a design method for the damping coefficient of a main spring compression type low-frequency vibration-isolated vehicle seat shock absorber, and belongs to the technical field of vehicle seats. Previously, there was no reliable design method for the damping coefficient of the main spring compression type low-frequency vibration isolation vehicle seat shock absorber. Most of them used the "experience + trial and error" design method, which could not meet the requirements of modern CAD design and rapid development of vehicle seats. The design method of the damping coefficient of the main spring compression type low frequency vibration isolation vehicle seat shock absorber provided by the present invention can adjust the shock absorber according to the structural parameters of the main spring compression type low frequency vibration isolation vehicle seat, the mass of the occupants and the driving conditions of the vehicle. The damping coefficient is designed quickly, accurately and reliably, avoiding the defects of trial and error in traditional design methods. The method can improve the design level, quality and vibration isolation performance of the main spring compression type low-frequency vibration isolation vehicle seat, reduce the design and test cost of the seat, shorten the design cycle, and accelerate the development speed of the seat.

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 ...
