技术领域technical field
本实用新型涉及乘用车悬置系统台架耐久试验开发领域，特别是涉及一种发动机悬置，变速箱悬置的三轴耐久台架。The utility model relates to the field of durability test development of a passenger car suspension system bench, in particular to a three-axis durable bench for engine suspension and gearbox suspension.
背景技术Background technique
乘用车悬置系统作为衔接动力总成和车身的部分存在，主要作用是支撑动力总成，减少动力总成的震动对整车的影响，限制动力总成的抖动量。在台架试验中悬置系统所受单方向或两个方向载荷情况进行模拟，无法较好地模拟悬置系统在整车中实际受力情况。The suspension system of a passenger car exists as a part connecting the powertrain and the body. Its main function is to support the powertrain, reduce the impact of the vibration of the powertrain on the vehicle, and limit the vibration of the powertrain. In the bench test, the single-direction or two-direction loads of the suspension system are simulated, which cannot better simulate the actual stress of the suspension system in the vehicle.
现有技术中的单轴悬置装置，如图8所示只能对发动机悬置进行X向动态加载，此试验台架可以同时对悬置的X,Y,Z三方向进行动态加载，进而更真实地模拟了悬置在实车中的状态；一般其他零件的多轴试验的迭代反馈响应方式，传感器在连杆后方，进行迭代时的反馈响应因为连杆重量惯性、装置重量惯性、装配位置等因素不能真实地模拟试件本身的响应。The single-axis mounting device in the prior art can only dynamically load the engine mount in the X direction as shown in Figure 8, and this test bench can dynamically load the mount in the X, Y, and Z directions at the same time, and then It more realistically simulates the state of the suspension in the real vehicle; in general, the iterative feedback response method of the multi-axis test of other parts, the sensor is behind the connecting rod, and the feedback response during iteration is due to the weight inertia of the connecting rod, the weight inertia of the device, and the assembly Factors such as location cannot truly simulate the response of the specimen itself.
