The Finite Element Analysis

On the basis of working characters, taking a hydraulic excavator as an example, an integrated and refined finite element model of working mechanism was established. Selected four typical working conditions, the strength analysis was made for the assembled working mechanism. According to the finite element analysis, the structure of the working mechanism was improved. The improved working mechanism met the required strength design after increasing the hydraulic system pressure.The results show that this analysis method of working mechanism can provide reference for the excavator working mechanism design.

In order to investigate the essence of sticking for drill rod served in underground coal mine, a comprehensive solution combing finite element analysis with fuzzy proportion–integration–differentiation on the drilling rig is proposed. First, the structure and working mechanism of the drilling rig are studied; then, the static and modal analyses on the drill rod with finite element analysis are performed according to the actual working conditions of the drilling rig. Furthermore, a load-sensing hydraulic power system of the drilling rig is built, and the co-simulation with AMESim and Simulink is performed on the response, overshoot, and vibration, when the hydraulic power is controlled with the conventional control method, proportion–integration–differentiation control method, and fuzzy proportion–integration–differentiation method, respectively. The simulation results show that the strength, stiffness, and vibration frequency of the drilling rig model meet the working requirements, and no resonance occurs; furthermore, the load-sensing hydraulic power system with fuzzy proportion–integration–differentiation method is preferable than the other two control methods.

Composite Soil Nailing

Combined with one foundation pit engineering in Guangzhou, the method was adopted in this paper, by which the in-situ test and finite element analysis were integrated. According to situation of study and demand of engineering, the study in composite soil nailing walls system was focused on working mechanism. The law of soil-nailing support technology for deep excavation was pointed out and summarized to provide reference to similar projects.
