Swing component anti impact test device

F. 2.2 Test Block

It is an aluminum ball with a diameter of 160 mm ± 5 mm and a weight of 4.6 kg ± 0.05 kg. The surface roughness of the aluminum ball is less than 25 p μ m, which causes impact

The impact between the surface and the accelerometer is uniformly transmitted.

F. 2.3 Accelerometer

Can measure three-axis acceleration. Installed at the center of gravity of the test block (F.2.2), the error between the sensitive axis and the direction of motion of the test block shall not exceed 2 °.

F. 2.4 Chain

Quantity 2, diameter 6mm, length 1600mm (from shaft to test block).

F. 3 Experimental Procedures

F. 3.1 Test Preparation

Hang the test block, adjust the position between the test block and the swinging component so that the test block is located within the motion plane of the swinging component, and the swinging part

The front end of the component happens to touch the test block, at the same height as the center of gravity of the test block.

F. 3.2 Release the swinging component

Lift the swinging component to the 60 °± 1 ° release position, and if the swing is less than 60 °, hit the test block at the maximum swing position.

F. 3.3 Data Collection

Collect 10 impact data with satisfactory impact effects. Measure and record the peak impact acceleration.
