The invention relates to a pendulum bob-type impact response spectrum testing bed which comprises a base, a guide rail, a sliding block and a bed face. A front waveform generator is fixed at one edge of the bed face, a back waveform generator is arranged on the base, the pendulum bob-type impact response spectrum testing bed further comprises a reducer fixedly connected with a left support, a motor connected with the reducer, a small gear connected with the reducer, a clutch and a pendulum bob rotation shaft, a big gear of the clutch is meshed with the small gear, the big gear of the clutch is fixedly connected with the pendulum bob rotation shaft, a friction hub of the clutch is fixedly connected with the pendulum bob rotation shaft, and the pendulum bob rotation shaft is supported by bearings fixed on the left support and a right support. The pendulum bob-type impact response spectrum testing bed further comprises an oscillating bar fixed on the pendulum bob rotation shaft and a pendulum bob fixed on the oscillating bar. The pendulum bob-type impact response spectrum testing bed achieves stable and rapid promotion of the pendulum bob and improves testing efficiency. The pendulum bob-type impact response spectrum testing bed enables the pendulum bob to slowly stop to achieve secondary impact resistance through friction plates and the friction hub. The pendulum bob-type impact response spectrum testing bed achieves bed face restoration, improves waveform quality and guarantees waveform consistency.
