Abstract
An electro-shaker vehicle test stand for vehicle evaluation includes a support frame, an electro-shaker mechanism and an interconnecting lever arm. The lever arm has an adjustable length. The test stand includes a spring table having a spring table plate and a spring table frame that is parallel to and spaced a predetermined distance below the spring table plate, a guide rod having a lower end attached to the spring table frame and an upper end attached to the spring table plate and a spring having an upper end attached to the frame and a lower end attached to the spring table frame. Activation of the electro-shaker mechanism induces an oscillatory movement of the spring in a vertical direction so that the spring table and vehicle are correspondingly displaced in a vertical direction.
