Principles of impact testing machine

The impact testing machine can be divided into manual pendulum impact testing machine, semi-automatic impact testing machine, non-metal impact testing machine, digital display semi-automatic impact testing machine, microcomputer controlled impact testing machine, and digital display fully automatic impact testing machine.
The battery is fastened to the test equipment with rigid mounting parts that can support all mounting surfaces of the battery, each battery should withstand a total of three equal-order impacts. The impact should be applied in each of the three mutually perpendicular directions unless the battery has only two axes of symmetry, in which case the test is only performed in both directions. Each impact must be applied in the normal direction of the battery surface. Each impact of the battery must obtain such acceleration, that is, at the initial 3ms, the small average acceleration is 75g (g is the local gravity acceleration). The peak acceleration should be between 125g and 175g. The battery should be tested at 20±5°C (68±9°F).
