Indirect measurement method for digging force of hydraulic excavator
摘要
Abstract
The digging force of hydraulic excavator is an important parameter reflecting the working conditions of the excavator. In this study, by analysis of the working mechanism of the excavator, a mathematical model reflecting the relationship between the cross-section stress of the linkage mechanism and the digging force of the bucket was established, and a new method for measuring the digging force was proposed. Furthermore, the cross-section stress values of the linkage mechanism under different digging forces were obtained by finite element simulation, and the error between simulation results and theoretical results was about 8％, which verifies the feasibility of the proposed measurement method for the digging force of hydraulic excavator.关键词
