4Structure and Performance

This testing machine consists of a body, an impact pendulum, a sample support, a measuring device, a control mechanism, and other parts

1Body: composed of a crossbeam, angle positioning mechanism, and level.

2Impact pendulum: composed of an upper connecting sleeve, pendulum rod, pendulum, positioning block, impact blade, etc. The energy of the pendulum is2The main pendulum and4Composed of counterweight weights.2The main swing hammers are1JWeighing body with large pendulum. There are counterweights available4The sets are respectively2.75J、5.5J、11J、22JCounterweight (steel stamps are displayed on all counterweights). Users can choose different counterweights according to their needs.

3Sample support: composed of jaw support and jaws. Before the experiment, the appropriate pendulum energy can be selected according to the sample requirements (test type).

4Control mechanism: composed of a release mechanism and a handle. This institution fixes the impact pendulum in place150At the position of °, and automatically drop the hammer for impact.

5Measurement device: composed of a digital acquisition system. Display the energy consumed by the sample after being impacted. The impact energy is calculated according to the following formula:

E=Pd (cosβ-cosα)

In the formula:Pd——Impact white torque (constant)

α - measured value of pre swing angle of impact pendulum (constant)

β - angle of rise after impact

In this experiment, as long as the elevation angle β is measured, the energy can be calculatedEValue. The digital display system of this testing machine is designed based on the above principles, so it can directly read the final data.
