| Abstract: | The dynamic response of the loading and unloading process in the working state of cylindrical supporting shell of portal crane is analyzed. The finite clement method is used and the influence of wind load is taken into account. The inspection system is developed and used to inspect the online working state . The result shows this system can ensure the normal operation of crane and avoid accident. |
