The water slide equipment can be roughly divided into two categories: one is that the water park equipment has a large water slide with a length of tens of meters and hundreds of meters to enjoy; the other is the water slide commonly used in kindergartens with the function of playing with water.
The former kind of water slide equipment is for tourists to slide. The structure is safe and the stability is very important. Slide equipment is on a large scale.
Amusement park equipments facilities belong to class B special equipment. Each set of equipment must be inspected and accepted by China Special Equipment Inspection Institute, and can be used only after the certificate is issued. Most of the slide equipment is installed outdoors, and the natural environment has a great influence on the structure of the landslide mass.
Therefore, in the stage of water skiing design, it is necessary to calculate and analyze the strength, rigidity, fatigue strength, stability, anti-overturning and anti-sliding of the structure, to meet the safety factor required by the corresponding specifications, prepare the formal calculation specifications, and have the corresponding qualified engineers of China Special Equipment Inspection Institute audit and issue the evaluation report before putting into production. The first batch of equipment must be manufactured by China Special Equipment Inspection Institute, which is responsible for it. After the type test report is issued, qualified engineers and quality engineers can be appointed.
Load, live load, wind load, snow load, earthquake load and impact load must be considered when calculating and analyzing the structure of slide equipment in water park equipment. The wind load can be divided into working load and non-working load. In the design of amusement park equipments
facilities, the wind load in the working state is calculated according to the operating wind speed of 15m / s, and the non-working state is calculated according to the wind load once every 50 years.
The snow load is calculated according to the wind load once every 50 years after the installation of the device, and the seismic load is calculated according to the 8 degree fortification intensity, which is equivalent to 0.2g of the design basic acceleration. When calculating the collision load, the impact of amusement facilities may occur in the process of motion, which is usually not accurately calculated in the design. Therefore, in the strength calculation, the load and live load must be multiplied by the impact coefficient, and the corresponding impact coefficient shall be selected according to the speed of the slide equipment.
The water slide structure of water park equipment includes FRP slide, steel structure and concrete foundation. In view of the particularity, importance and complexity of the slide equipment structure, the finite element method is introduced into the analysis of the water slide structure. The finite element method is suitable for all kinds of complex mechanisms in the water slide equipment, and has become one of the effective analysis tools. After the introduction, the traditional analysis method is completely changed, the stress analysis is more accurate and comprehensive, and the water sliding structure check and design optimization are more beneficial.
