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.
