The tumbling barrel drop test is not equivalent to the drop test, but a supplementary of the drop test. The free fall drop test is to test the maximum load that the product can withstand when an accidental drop occurs during use. Rotating drum drop test is to simulate the repeated rotating drum drop to determine the performance of finished products and parts of various electrical products, connections, sealing parts.
The free fall drop test is a single drop test for the specific posture of the sample. You can set the height of the drop, and the sample can be firmly clamped by the pneumatic arm, which can realize the free fall of the corners, edges, surfaces of the product in multiply desired postures. The sample can be evaluated after a single drop. The tumbling barrel drop test has no requirements for the posture of the sample during the drop, and the whole falling state is more random and repeated.
The tumbling barrel drop tester is more widely used. In addition to consumer electronics, such as electrical connectors, product accessories are also usually tested by rotating drum drop testers. It is mainly used to determine the product’s resistance to repeated falling, tumbling and scratching.
Both rotating drum drop tester and free fall drop tester are mainly used in the drop test of consumer electronic products such as mobile phones, IPADs.
