Meteorological lifting pole, meteorological lifter, meteorological telescopic mast, meteorological lifting tower mast, meteorological lifting bracketIt has the advantages of large load, low noise, fast rise and fall, low seismic resistance, strong self-falling buffer performance and stability. Our company's meteorological lifting pole, meteorological lifter, meteorological lifting platform, meteorological lifting bracket products are made of high strength aluminum alloy, light weight, which can meet the needs of different fields and occasions for height and load, and play a role in night rescue and rescue of various natural disasters and emergencies. It plays an important role. In addition, the company's products are also widely used in golf, large football stadium night lighting and so on.
II. Performance indicators
1) Understanding of Wind Resistance of Masts
Wind resistance of mast is one of the important technical indexes of mast products. Every customer wants to know how much wind power the mast can withstand after installing the load, but at present, few people can answer this question accurately. This is because the wind resistance of masts depends on the following three factors:
Material and Structure of A Mast
Use Height of B Mast
Weight, Volume and Shape of C Load
When the above three conditions are clear, the specific index of wind resistance can be obtained in the following three ways:
(1) Finite element analysis is used for theoretical calculation.
(2) In the simulation experiment, the wind of different grades is converted into wind pressure, and then tested by physical method (tensiometer).
(3) The mast and load are placed in the wind tunnel to simulate the wind speed.
Among the three methods mentioned above, the third one can provide more realistic values. However, the cost and conditions of wind tunnel experiments are very high. For example, if a mast with loads is 18 meters tall and tested in a wind tunnel, is there such a large wind tunnel? Can you do it? How much does it cost? It's all a problem. Therefore, for the mast manufacturer, the wind resistance index of the mast can only be provided by the above two methods.
2) A Method for Calculating the Wind Resistance of Masts
This calculation method is that our company employs experts from related fields, according to our company.Meteorological lifting pole, meteorological lifter, meteorological telescopic mast, meteorological lifting tower mast, meteorological lifting bracketThe material, structure and height of the mast are given for reference only.
For example, the wind resistance of A4-270-2300-7600 lifting poles is calculated according to the reference wind speed of 100 km/h.
