The integrated design of the base of the main frame and the column, the overall casting process, good rigidity, and improve the stability of the test; the pendulum shaft is supported by simply supported beams, and the radial load distribution of the bearing is reasonable, which greatly reduces the energy loss caused by bearing friction ; .Using geared motor to lift the hammer, the hanging pendulum is stable; it is equipped with safety protection pins and is equipped with a fully enclosed protective cover.
The testing machine is equipped with a load cell and an angular displacement sensor, with high-speed sampling, storage and calculation functions; it can provide: impact velocity, impact time, impact energy, absorbed energy, displacement, crack formation energy, crack expansion energy, yield force, yield Time, yield displacement, yield energy, maximum force, time at maximum force, displacement at maximum force, energy at maximum force, unstable crack growth initiation force, unstable crack growth termination force, unstable crack growth termination displacement , unstable crack growth initiation energy, unstable crack growth termination energy and other eigenvalues.
