The integrated design of main frame base and column and integral casting processing have good rigidity and improve the stability of the test; The pendulum shaft is supported by simply supported beam, the radial load distribution of the bearing is reasonable, and the energy loss caused by bearing friction is greatly reduced The reducer motor is used to lift the hammer, and the hanging pendulum is stable; It is equipped with safety pin and fully enclosed protective cover.
The testing machine is equipped with force sensor and angular displacement sensor, which has the functions of high-speed sampling, storage and operation; It can provide: impact speed, impact time, impact energy, absorbed energy, displacement, crack formation energy, crack propagation energy, yield force, yield time, yield displacement, yield energy, maximum force, time at maximum force, displacement at maximum force, energy at maximum force, starting force of unstable crack propagation, ending force of unstable crack propagation Multiple eigenvalues such as unstable crack propagation termination displacement, unstable crack propagation initiation energy, unstable crack propagation.
