Omnidirectional fatigue vibration test stand for automobile seats

Abstract

The invention discloses an omnidirectional fatigue vibration test stand for automobile seats, comprising a chassis, a seat mounting platform, a horizontal vibration device, a vertical vibration device and a hip stimulator. In the invention, a horizontal and vertical compound vibration structure is adopted, respective independent driving mechanisms are arranged by combining the device stimulating plastic hips of drivers and passengers, and the vibration at single direction of seats can be realized according to demands so as to obtain single seat fatigue parameters; and compound external force vibration can be carried out by simultaneous driving of the driving mechanisms to carry out vibration test of sine wave so as to obtain the fatigue parameters of the seats during omnidirectional vibration. Due to few components, the test stand has simple structure, easy disassembly and assembly, convenient operation and manufacturing and use cost conservation.

Description

technical field [0001] The invention relates to an automobile seat detection device, in particular to an automobile seat omnidirectional fatigue vibration test bench. Background technique [0002] Car seat testing is an important part of car parts testing. The seat load vibration test is a process of simulating the real environment to provide real theoretical data for car manufacturing. Vibration is an important factor affecting the life of the car seat. During the operation of the car, the car will mainly produce vertical and horizontal vibrations relative to the ground due to road reasons and working conditions such as starting and braking; the seat on the car will produce the same vibration . At the same time, the driver and occupant sitting on the seat will also generate compound external force on the seat due to the vibration inertia.

AI Technical Summary

Problems solved by technology

[0003] In the prior art, there is a test bench that meets the requirements of the vehicle seat vibration test for simulating composite external forces. This test bench has relatively complete functions and can meet the testing needs; however, the existing test bench for simulating composite external force has many accessories and complex structures. , high cost, low precision, difficult to maintain; and due to cost issues, it is difficult to popularize and apply in small and medium-sized enterprises

However, the test bench with simple structure and low cost can only realize vibration in a single direction, and cannot carry out compound vibration at the same time, and cannot realize the simulated compound external force vibration experiment required by car seats.
