Optimized Design of Bucket Rod Mechanism of Agricultural Excavator based on ANSYS and Design-Expert

JKW-20 mountain agricultural excavator bucket rod mechanism exists design redundancy, under the premise of ensuring safety and reliability, in order to solve the problem of material redundancy of the bucket rod mechanism and realize the improvement of lightweighting, the coupling model of the bucket rod mechanism of the excavating device of the agricultural excavator is established, and the new structure of topology optimization of the bucket rod mechanism is determined through the static simulation and topology optimization of the ANSYS software. Since the topology optimization structure does not meet the actual production requirements, based on the optimization results to design the bucket rod variables, determine the optimization objective function, the use of Design-Expert to optimize the size of the bucket rod mechanism to solve. From the comparison of the optimization results, it can be seen that the bucket rod structure optimized by Design-Expert has a lighter mass and greater strength than the original structure, and this method not only saves the production cost of the JKW-20 mountain agricultural excavator, but also provides optimization design ideas for similar mechanisms.
