Each part or component in the inflatable sports park mechanical equipment has a specific function, such as transmitting motion, force, realizing prescribed action, maintaining fixed geometric shape and so on. Failure includes complete loss of the original function; reduced function and serious damage or hidden danger, continued use will lose reliability and safety.

1. Wear
Wear is a basic type of inflatable sports park component failure. Generally speaking, wear refers to the phenomenon that the size, shape, and surface quality of parts change under the action of friction, resulting in the continuous loss of materials.
2. Fracture
Parts and weld fractures occur frequently in inflatable sports parks, such as shaft fractures, stress steel structure fractures, and weld fractures. According to the classification of load properties, fracture can be divided into one-time loading fracture and fatigue fracture.
The deformation of inflatable sports park parts can be divided into elastic deformation and plastic deformation. When the deformation disappears completely after the external force is removed, it is called elastic deformation. The elastic deformation will not cause the failure of the parts. However, exceeding the elastic limit is called excessive elastic deformation, which usually causes plastic deformation.
