Description

technical field

[0001] The invention belongs to the technical field of mechanical design and relates to vibration simulation, in particular to a wide-frequency large-displacement vibration simulation exciter suitable for road simulation of high-speed crawler vehicles. Background technique

[0002] High-speed tracked vehicles have the characteristics of strong ground adaptability and are widely used in the field of national defense. The vibration damping performance of the running system of high-speed tracked vehicles is an important guarantee for the off-road performance, comfort and stability of the upper installation platform of high-speed tracked vehicles. Vibration simulation exciter adapted to road simulation of high-speed tracked vehicles By applying vertical force to the road wheels of high-speed tracked vehicles, the displacement data of the actuators measured in the test laboratory are almost exactly the same as those under the original road conditions, which can gr...
