1. Classification of water slide equipment by users
Water slide equipment can be roughly divided into two categories. One is the large water slide with tens of meters or even hundreds of meters in the water park equipment; the other is the kind commonly used in kindergartens with added water play function. Water slide. The former type of water slide equipment is for tourists to slide, and the safety and stability of its structure are very important.
2. Production qualification requirements of large-scale water slide equipment
Water slide equipment belongs to water amusement facilities in large water park equipment, and belongs to the category of special equipment. The grade is B. Each set of equipment must be inspected, tested and accepted before being used with a certificate.
Most of the water slide equipment is installed outdoors, and the natural environment has a great influence on the slide structure. Therefore, in the design stage of the water slide, the structure must be calculated and analyzed for its strength, stiffness, fatigue strength, stability, overturning resistance and side-slip resistance, to achieve the safety factor required by the corresponding code, and prepare a formal calculation manual, and It can be put into production only after a qualified engineer has reviewed and issued an appraisal report. The first set of equipment must be inspected on site by an engineer, and a type test report can be used and mass produced.
3. Structural analysis of water slide equipment
When calculating and analyzing the structure of water slide equipment in water park equipment, permanent load, live load, wind load, snow load, seismic load and impact load must be considered. Permanent load is generally the topic of self-weight in water slide equipment; live load is only the load and water load of the rider; wind load is divided into working state load and non-working state load, and the amusement equipment is designed according to the maximum operating wind speed of 15m/s Calculate the wind load in the working state, the non-working state is calculated according to the maximum wind load of the equipment installation site in 50 years; the snow load is calculated according to the maximum wind load of the equipment installation site in 50 years; when calculating the seismic load, the fortification intensity is 8 degrees , Which is equivalent to the calculation of the design basic acceleration of 0.2g; when calculating the impact load, the amusement device may have an impact during the movement process, and it is generally impossible to accurately calculate it during the design. Therefore, when calculating the strength, the permanent load and live load must be multiplied by the impact coefficient. In the water slide equipment, the impact coefficient corresponding to the impact coefficient should be selected according to its maximum speed. These are also factors to consider when making the water park investment.
The water slide structure in the water park equipment includes three parts: glass steel slide, steel structure, and concrete foundation. In view of the particularity, importance and complexity of the structure of water slide equipment, the finite element method is introduced in the analysis of water slide structure. The finite element method is suitable for various complex mechanisms in water slide equipment and has become one of the effective analysis methods. one. After the introduction, the traditional analysis method has been completely changed, making the force analysis more accurate and comprehensive, which is more conducive to the structural check and design optimization of the water slide.
