Power assembly body vibration test bench

The invention relates to the technical field of automobile power assembly testing, and discloses a power assembly body vibration test bench which comprises an iron floor, two parallel longitudinal beams are installed on the iron floor through a base, and a plurality of cushion assemblies used for being connected with a power assembly are arranged on the inward sides of the two longitudinal beams. According to the power assembly body vibration test bench, resonance with a power assembly under each test working condition can be avoided, the accuracy of a measured value is ensured, vibration under the test working condition is also prevented from being excessively transmitted to the bench, noise is reduced, and the use reliability and the service life of the bench are ensured. 本发明涉及汽车动力总成测试技术领域，公开了一种动力总成本体振动测试台架，包括铁地板，铁地板上通过底座安装有两个互相平行的纵梁，两个纵梁朝内一侧设有用于连接动力总成的若干个软垫总成。本发明动力总成本体振动测试台架，可以避免各测试工况下与动力总成产生共振，保证了测量值准确性，同时也避免测试工况下振动过度传递到台架，降低了噪声，保证了台架使用的可靠性和寿命。
