Throttle valve vibration test bench

The utility model relates to the technical field of vibration test, and discloses a throttle valve vibration test bench, which comprises a test bench, a power supply device connected with external power storage equipment is fixed at the top end of the test bench, high-frequency electric lifting rods are symmetrically arranged at the top end of the test bench, and the high-frequency electric lifting rods are electrically connected with the power supply device. According to the vibration test bed for the throttle valve, when the throttle valve needs to be detected, the throttle valve is firstly fixed on the clamping tool, then the power supply is started, the power supply supplies power to the high-frequency electric lifting rod to start, parts fall into an inner cavity of the collecting bin, and then the parts can be detected. And then acting force caused by falling of the falling part is relieved through a buffer spring, a buffer rod and a buffer plate, and therefore the situation that the part is damaged due
