Maximum compression refers to the amount of force or energy that a train buffer can absorb before it reaches its limit and can no longer compress any further. It is an important factor in the design and safety of train buffers.
Maximum compression is important because it determines the level of impact a train can withstand during collisions or sudden braking. It also helps to prevent damage to the train and its passengers.
Maximum compression is typically measured in kilonewtons (kN) or megapascals (MPa) and is determined through rigorous testing and simulations. The results are then used to set safety standards and guidelines for train buffers.
The material and design of the train buffer, as well as the speed and weight of the train, can all affect the maximum compression. Other factors include the condition of the tracks and the type of coupling system used.
If a train buffer does not have a sufficient maximum compression, it may not be able to absorb enough energy during collisions or sudden braking, resulting in damage to the train and potential injuries to passengers. It can also lead to derailments and other accidents.
