Vertical bucket elevator is a kind of mechanical conveying equipment with fixed device

which has the advantages of strong conveying capacity

high lifting height

stable and reliable operation

long service life and so on. Reducer is the key component of vertical bucket elevator. In order to obtain the optimal solution of reducer efficiently

an improved northern goshawk optimization algorithm based on sprint decisive strategy is proposed. Two classical nonlinear constrained engineering examples of pressure vessel and cantilever beam are used to verify the performance of the improved northern goshawk algorithm. The results show that the improved northern goshawk algorithm has good convergence speed. On this basis

the reducer of vertical bucket elevator is optimized. The results show that the center distance of the reducer is reduced from the initial 720 mm to 680. 16 mm

which is 5.33% lower than the initial value. The improved northern goshawk optimization algorithm can be used as an efficient optimization algorithm to solve practical engineering problems.
