Mechanical Properties' Simulation Analysis of a Tower Slewing Platform
To study the safety of a tower slewing platform structure,a three dimensional numerical model is established with actual sizes and operating conditions. The structural force,pressure margin of hydraulic system with different wind loads,and the influence of lift platforms' amount are researched which are concerned closely in use. In working condition,the maximum stress of structure is 223.98MPa,and the structure safety factor is 1.58. The pressure margin of hydraulic system is calculated with the worst wind direction and the maximum windward area. When the platform is opened with permitted wind speed,the hydraulic system pressure can not be lower than 5.40MPa,and the pressure margin is 2.96. The structure safety factor is 1.35 when the number of lift platforms is 9. According to the results of simulating calculation,the security of the slewing platform can be confirmed. The simulating model can provide a reference for the slewing platform's application.
