PENDULUM HAMMER FOR TESTING MATERIAL SPECIMENS WITH REPEATED IMPACTS Russian patent published in 2011 - IPC G01N3/34 

FIELD: physics.

SUBSTANCE: pendulum hammer for testing material specimens with repeated impacts has a stand on which is mounted a pendulum with a load and a specimen gripper mounted on the pendulum, a first platform whose axis of rotation coincides with the axis of oscillation of the pendulum, a locking device for joining the first platform with the axis of the axis of the pendulum, a rotary drive for the first platform and a support for interaction with the pendulum, according to the invention, has a second platform whose axis of rotation coincides with the axis of oscillation of the pendulum, a locking device for joining the second platform with the first platform and the locking device for joining the second platform wit the stand. The support is on the second platform. The rotary drive is bidirectional and has an additional specimen gripper and a flexible member mounted on the additional gripper. The load is attached to the flexible member.

EFFECT: conducting tests with impact loads in form of separate impacts and series of damped impacts in two opposite directions.
