Embodiment Construction

[0033] specific implementation plan

[0034] The present invention will be further described in detail through an embodiment below.

[0035] A vehicle is equipped with a main spring compression type low frequency vibration isolation vehicle seat. The structural diagram of the seat is as follows figure 2 As shown, its passenger mass m b =75kg, the ratio coefficient of occupant mass borne by the seat η=0.73, the mass of the seat panel m 0 =8kg, the vertical deformation u of the seat suspension at the static equilibrium position e = 30mm, the angle between the shear bar and the seat bottom plate θ = 45°, the length of the shear bar L = 600mm, the length of the connecting rod r = 40mm, the acceleration of gravity g = 9.8m / s 2 . In order to effectively isolate the vibration, the stiffness of the auxiliary spring of the seat suspension needs to be designed.

Abstract

The invention relates to a method for designing the stiffness of an auxiliary spring of a main spring compression type low-frequency vibration-isolated vehicle seat suspension, and belongs to the technical field of vehicle seats. Previously, there was no reliable design method for the secondary spring stiffness of the main spring compression type low-frequency vibration isolation vehicle seat suspension, and 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 auxiliary spring stiffness of the main spring compression type low frequency vibration isolation vehicle seat suspension provided by the present invention can adjust the seat suspension according to the structural parameters of the main spring compression type low frequency vibration isolation vehicle seat and the occupant mass of the seat. The stiffness of the auxiliary spring 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 method for designing the stiffness of an auxiliary spring of a main spring compression type low-frequency vibration-isolated vehicle seat suspension. 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 stiffness of thi...
