3 Terms and Definitions
For the purposes of this standard, the terminologies and definitions established in GB/T 4549.4-2004 and the following ones apply.
3.1
rating impact velocity
impact velocity of draft gear when it reaches the rated resistance in impact test
3.2
maximum impact velocity
impact velocity of draft gear when it reaches the maximum resistance in impact test
3.3
recoil
after draft gears absorb energy, recoil refers to the energy released without being dissipated. In drop hammer test, it refers to the energy value calculated by multiplying the height difference between the minimum point of hammerhead and the peak point the hammerhead rebounds by the weight of hammer block in the cycle that the hammerhead drops for the first time and rebounds upwards
