The invention provides a test bed for a vehicle suspension device, The test bed comprises an upper cover plate, a functional mechanism, a base and a frame. The frame is installed between the upper cover plate and the base. The functional mechanism is assembled between the upper cover plate and the base. The functional mechanism is installed inside the frame. The functional mechanism comprises massblocks, an upper platform, a suspension dynamic travel displacement sensor, a lower platform, guiding columns, a servo cylinder, a working table, an analog wheel spring, a force sensor, a suspensionspring, suspension spring fixing seats and an upper platform displacement sensor. The test bed of the invention has the following beneficial effects compared with the prior art: the vibration dampingtest of the suspension device can be performed and the damper performance test can also be performed to increase the functionality and reduce the equipment cost.
