Description

A subway seat system for reducing the effect of lateral inertia

Technical field

The invention relates to the technical field of mechanical structures, in particular to a subway seat system that reduces the effect of lateral inertia.

Background technique

The property of an object in a static state or in a uniform linear motion state is called inertia. Inertia is an inherent property of an object, which is expressed as a degree of resistance of an object to changes in its motion state. Mass is a measure of the inertia of the object. When the external force on the object is zero, the inertia shows that the object keeps its state of motion unchanged, that is, remains stationary or moves in a straight line at a uniform speed; when the external force acting on the object is not zero, the inertia shows the difficulty of the external force changing the state of movement of the object. Under the same external force, an object with a smaller acceleration has a larger mass and a larger inertia, and an object with a larger acceleration has a smaller mass and has a smaller inertia. Therefore, people take the subway at any time (by external force or not by external force) , Under any circumstances (stationary or moving), it will not change, let alone disappear, so when the subway decelerates, due to the physical properties of the human body, it will cause the body to lean forward in the direction of movement, which makes people comfortable in riding the subway.
