Structural analysis of water slide equipment

  The water slide equipment is roughly divided into two categories. One is a large water slide with a tens of meters of super-long slides in the water park equipment; the other is the kind of water play that is commonly used in kindergartens. Water slides.


  The former water slide equipment is a device for tourists to slide, and the safety and stability of the structure are very important. The water slide equipment belongs to the water amusement facilities in the large water park equipment. It belongs to the category of special equipment. The grade is B grade. Each set of equipment has to pass the inspection, inspection and acceptance of the China Special Equipment Inspection Institute, and can be used after issuing the certificate. Most of the water slide equipment is installed outdoors, and the natural environment has a great influence on the structure of the slide. Therefore, in the design stage of water slides, the structural strength, stiffness, fatigue strength, stability, anti-overturning and anti-slip properties must be calculated and analyzed to achieve the safety factor required by the corresponding specifications, and formal calculation specifications are prepared. China Special Equipment Testing Institute has the qualifications of engineers to audit, and the production report can be put into production after the production of the appraisal report. The first set of equipment must be inspected by the professional and qualified engineers of China Special Equipment Testing Institute, and the type test report can be used and mass production. .


  For the calculation and analysis of water slide equipment structures in water park equipment, permanent loads, live loads, wind loads, snow loads, seismic loads and impact loads must be considered. The permanent load is generally the self-weight of the topic in the water slide equipment; the live load only takes the load and water load of the person itself; the wind load is divided into the working state load and the non-working state load, and the maximum operating wind speed is 15m/s in the design of the amusement facility. 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 defense intensity is 8 degrees. It is equivalent to the calculation of the basic acceleration of 0.2g; when calculating the impact load, the amusement facilities may have an impact during the movement, and the design cannot generally be accurately calculated. Therefore, in the calculation of the strength, the permanent and live loads must be multiplied by the impact factor. In the water slide equipment, the impact coefficient corresponding to the impact coefficient is selected according to its maximum speed.


    The water slide structure in the water park equipment includes three parts: glass fiber reinforced plastic slide, steel structure and concrete foundation. In view of the particularity, importance and complexity of water slide equipment structure, and the introduction of finite element method in the analysis of water slide structure, the finite element method is applicable to various complex mechanisms in water slide equipment, and has become an effective analytical tool. one. After the introduction, the traditional analysis method has been completely changed. It is a more accurate and comprehensive analysis of the force analysis, which is more conducive to the water slide structure check and design optimization.
