Research on relationship between cable diameter angle and structural stress of flexible ferris wheel
The size of the cable diameter angle of the ferris wheel is closely related to the length of the main shaft.The larger the angle,the longer the length of the main shaft,and the better the overall stability.However,the longer the main shaft is,the greater the torque will be,resulting in a series of problems such as the increase of the main shaft consumption,the difficulty of manufacturing and processing,the difficulty of hoisting,and the increase of cost.Therefore,the length of main shaft was used instead of the cable diameter angle,and the MIDAS Gen software was used to study the stress ratio change trend of the structural members of the ferris wheel under the same load and different length of main shaft,that is,different cable diameter angles,by means of numerical simulation.The reasonable length of main shaft the ferris wheel was determined,and the reasonable cable diameter angle was determined.The problem of increasing the cable diameter angle in the case of limited wheelbase was solved by a new arrangement of spoke cable structure.
