Research On Bearing Structure Of High Altitude Amusement Equipment Based On Finite Element Method

High-altitude flying amusement equipment is a very common amusement equipment in today's amusement park.Because of the high-altitude flying bearing structure and complex structure form,the design of high-altitude flying structure should consider not only the general structural performance of high-rise structure,but also the deformation and safety performance of high-altitude flying structure.Therefore,it is necessary to carry out a comprehensive static and dynamic analysis of high-altitude flight to ensure that the force,deformation and safety performance of its structure can meet the requirements of the standard.The altitude flight equipment selected in this paper is 39m(excluding lightning rod height)with a bearing number of people is 30.The running height is 25 m,the turning radius is 16.2m in static state and 28.2m in running state.It belongs to a higher structure in the same kind of amusement equipment.In the finite element ANSYS software,the parameterized finite element model of the tower and rotating mechanism of high-altitude flying structure is established,the restraint and load are reasonably applied,and the static load conditions(extreme wind conditions,extreme snow conditions,earthquake conditions)and dynamic load conditions(working wind filling)of the two parts of the bearing structure of high-altitude flying tower and rotating mechanism are observed.Loading condition under loading condition,working wind plus bias load condition.The calculation shows that the maximum stress of the bearing structure of the high-altitude flying tower occurs in extreme wind condition,the maximum stress is 150 MPa,the maximum stress of the rotating support occurs in the acceleration condition of unbalanced load lifting,the maximum stress is 36.5 MPa,and the maximum stress of the skew pylon occurs in the full-load rotating acceleration condition,and the maximum stress is 31.2 MPa.According to the maximum stress of high-altitude flying structure under various working conditions,the strength and stability of the structure are checked to determine whether its safety factor meets the requirements of GB8408-2008 standard.Because the structure strength of skew hanger is surplus,the structure of skew hanger bearing structure is optimized.The optimization scheme is to optimize the original design square tube of 100 mm x 4 mm to 50 mm x 4 mm square tube,and the maximum stress is 46.7 MPa.After checking,the safety factor meets the standard requirements,and the optimization is reasonable,which makes the high-altitude flying bearing structure more economical.And lightweight.In order to obtain the natural frequencies and mode shapes of the high-altitude flying bearing structure,the modal analysis of the high-altitude flying is also carried out in this paper,which provides data reference for avoiding the damage caused by the resonance of the structure.
