Aiming at the safety problem of sliding and even overturning risk of a large storage box when loading and unloading under the high wind speed,the numerical analysis method was used to analyze the lateral force and overturning moment received by the storage box under the different wind speeds.The numerical analysis results show that the storage box would not slide and overturn under the condition of average wind speed of 15 m/s and instantaneous wind speed of 25 m/s.Load experimental and verification were conducted for the storage box.The experimental results show that under the action of 3.193 N lateral tension,the storage box does not slip and overturn,which proves the accuracy of the numerical analysis results,and also proves that the loading and unloading of the storage box is safe under the conditions of average wind speed 15 m/s and instantaneous wind speed 25 m/s.
