doi:10.3901/JME.2024.23.076

Abstract

Abstract: The kinematics analysis of a new hydraulic loader working device is proposed. First, the degrees of freedom of the new hydraulic loader working device are calculated by using the modified Grübler-Kutzbach formula. The analysis shows that the working device can realize the rotation and vertical lifting motions of the bucket relative to the frame, which meets the working requirements of the hydraulic loader. Moreover, the mathematical model of forward and inverse kinematics of the new hydraulic loader working device is established based on the theory of mechanism motion loop, and the accuracy of the mechanismic position is verified by comparing the results of forward and inverse kinematics solutions with examples and simulations. Third, the joints space of the new hydraulic loader working device is established by using the Denavit-Hartenberg method, and the joints space of the working device is solved and analyzed to verify the accuracy of the mechanism motion process. Finally, by simulating a working cycle of the new hydraulic loader working device, its performance parameters such as the maximum unloading height, unloading distance, displacement, unloading and automatic return are analyzed, and the practicability of the new hydraulic loader working device is verified. The research results show that the new hydraulic loader working device meets the actual working requirements, and an important theoretical basis for the design of the hydraulic loader working device is provided.
