Outdoor cultural tourism equipment: How long is the lifespan of amusement equipment?
Release time:
2022-08-04
Combine the design lifespan of amusement facilities with actual needs. In most areas of our country, especially in economically underdeveloped regions, the individual business model remains the main model, and the economic benefits are not good. The operators are mainly middle-aged and elderly, with a generally low quality. Among them, 99% have not purchased equipment and personnel insurance, and have basically no ability to bear accident liability. So, how long is the lifespan of outdoor cultural tourism amusement equipment?

Combine the design lifespan of amusement facilities with actual needs. In most areas of our country, especially in economically underdeveloped regions, the individual household model is still the main model, and the economic benefits are not good.

So, outdoor cultural tourism amusement equipment: How long is the lifespan of amusement equipment?
Outdoor cultural tourism amusement equipment: How long is the lifespan of amusement equipment?
Some problems are prominent, with missing manufacturer information, and some even lack the manufacturer's manual and daily maintenance records; most equipment does not undergo regular maintenance, and necessary non-destructive testing is not performed on the main stress welds and main pin shafts during maintenance; the fiberglass used in passenger facilities is aging and damaged; the corrosion and wear of major structural components have not been checked; daily checks before equipment operation and no-load operation have not been effectively implemented, and equipment operation records are falsified; there are many instances of ungrounded metal shells in electrical equipment, especially in older equipment; there is a phenomenon where some equipment of the electrical safety device for human-induced short circuits, such as the mobile platform of space travel, is too outdated and does not meet current design standards.
Outdoor cultural tourism amusement equipment: What are the factors affecting lifespan and calculation methods?
The lifespan of amusement facilities refers to the period during which the product maintains safe working capability from the start of use to the end of use under the conditions specified by the designer or manufacturer. It is unsafe to continue using amusement facilities beyond their service life.
1. During the use of amusement facilities, they are affected by stress and strain, and almost all structures and components change shape and size relatively to withstand fatigue loads. Their main failure mode is fatigue failure. According to conventional fatigue strength design, it is assumed that the material has no initial cracks. After a certain number of stress cycles, cracks will form due to the accumulation of fatigue damage, and the cracks will continue to expand under stress cycles until a complete brittle fracture occurs. The number of stress cycles before crack formation is called the crack-free life; the number of stress cycles from crack formation to fatigue fracture is called the crack propagation life. The total life of a part is the sum of the two. Generally speaking, the structural life of the equipment is the basis for determining the natural service life of the entire equipment. Each stress cycle causes some damage to the parts, and this damage can accumulate; when the damage accumulates to a critical value, the parts will fatigue.
2. Another factor affecting the use of amusement facilities is wear life. When objects move relatively, the material on the friction surface is continuously worn away under the action of friction, such as wear between shafts and bearings, wear between gear teeth, wear between guide wheels and guide rails, etc. They destroy the matching size and strength of the parts, and when wear exceeds the allowable limit, the equipment will fail.
