Overview

Digital cantilever beam impact testing machine

Product Details

One purpose
The ZY-3003 digital cantilever beam impact testing machine is mainly used for measuring the impact toughness of non-metallic materials such as hard plastics (including plates, pipes, plastic foreign materials), reinforced nylon, fiberglass, ceramics, cast stones, and electrical insulation materials. It is an ideal testing equipment for material performance testing in the chemical industry, research institutions, and colleges.

Structure and properties
This testing machine consists of a body, an impact pendulum, a sample support, a measuring device, a control mechanism, and other parts
Body: composed of a crossbeam, angle positioning mechanism, and level.
Impact pendulum: composed of an upper connecting sleeve, pendulum rod, pendulum, positioning block, impact blade, etc. The pendulum energy consists of 2 main pendulums and 4 sets of counterweight weights. The two main pendulums are 1J and the counterweight body of the large pendulum. There are 4 sets of counterweights, namely 2.75J, 5.5J, 11J, and 22J counterweights (all counterweights have steel stamps on them). Users can choose different counterweights according to their needs.
Sample support: composed of jaw support and jaws. Before the experiment, the appropriate pendulum energy can be selected according to the sample requirements (test type).
Control mechanism: composed of a release mechanism and a handle. The mechanism fixes the impact pendulum at a 150 ° position and automatically drops the hammer for impact.
Measurement 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 pendulum moment (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 E value can be calculated. The digital display system of this testing machine is designed based on the above principles, so it can directly read the final data.
