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.

[0036] The design method of the secondary spring stiffness of the main spring compression type low-frequency vibration ...

Abstract

The invention relates to a design method of main-spring compression type low-frequency vibration-isolation vehicle seat suspension vice-spring stiffness 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 suspension vice-spring stiffness 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 suspension vice-spring stiffness can be designed rapidly, accurately and reliably according to structure parameters of the main-spring compression type low-frequency vibration-isolation seat suspension vice-spring stiffness and crew quality of the 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 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...
