Bucket wheel stacker reclaimer is a world-wide large-scale continuous bulk material handling equipment , because it belongs to the continuous production of machinery , high productivity, more and more the attention of the world , at present, has been widely used in mining, metallurgy, electric power , traffic , building materials and chemical sectors of large - scale open-pit storage yard , warehouses , power plants , gas and large ports and other places . , Cantilevered bucket wheel stacker reclaimer feeder flexible working structure action , a wide range of jobs and space requirements are relatively low , etc. , become the most commonly used form of structure . It is by the bucket wheel mechanism , forearm stand , columns , balance mechanism , slewing mechanism , portal , Running Gear and tail car . Which the institutions of the bucket wheel reclaimer main components , which is located in the forefront of the cantilever , the weight of a direct impact on the weight and balance of the machine , so it's lightweight lightweight design of the machine is of great significance . The purpose of this paper is to obtain an optimized bucket wheel wheel body . In this paper , finite element analysis software ANSYS platform on the use of progressive topology optimization method ( ESO ) on bucket wheel wheel body topology optimization , come to the best wheel material distribution model , a strain energy density as the element deletion criteria , and the use of the the checkerboard control method, and achieved good results . Then the results of the topology optimization to simplify and optimize the original model - curved spokes wheel body model , taking into account manufacturing , combined with previous experience in the design , put forward another model - straight spokes wheel body model , and the use of ANSYS vaginal discharge size optimization method - sub-problems , scanning law and order method , the two models to optimize the obtained optimal wheel body size , and ultimately determine the straight spoke wheel body as the final optimization results . Then the transient analysis and reliability analysis using ANSYS wheel body to prove optimal results model can meet the requirements . Bucket wheel stress test results and finite element analysis results were compared to verify the correctness of finite element analysis . Bucket wheel optimize the results of the analysis applied to real , compared with the same model weight reclaiming capacity has been substantially reduced field bucket wheel mechanism running smoothly , proving the effectiveness of the method .
