Four-channel road simulation test platform for NVH test

The invention discloses a four-channel road simulation test platform for an NVH test. The four-channel road simulation test platform comprises four loading units, two sets of X-direction adjustment driving systems and two sets of Y-direction adjustment driving systems; each loading unit comprises a clamp system, a sound insulation system, a power system and a distance adjusting system, the clamp system is fixed to the top of the power system and located above the ground, the power system is fixed to the top of the distance adjusting system and located below the ground, and the sound insulationsystem is fixed to the power system and located between the ground and the power system and used for noise below the ground; the two sets of X-direction adjustment driving systems are respectively arranged between the distance adjustment systems of the two loading units at the front end and between the distance adjustment systems of the two loading units at the rear end and are used for driving the loading units to relat
