Abstract: In this paper the character of loads exerted on bucket wheel was evaluated. The places of maximal stresses were determined by using finite element analysis. After this operation, a new wheel hub design was initiated. The first phase was related to development of new conceptions of the hub. The proposed conceptions were rated with respect to mass and total length of welds. This procedure led to selection of the most suitable design, which was optimized in order to minimize stress. The work at this stage consisted of continuous modification of the geometrical form, meshing of finite element model and structural analysis thereby providing information about stresses and deformations. The workmanship of the structural component and welded joints were defined according to DIN 22261 2:2006 standard.

Abstract: The paper first put CAD/CAE technology into the domain of hydraulic excavator research and exploitation. It was focused on the analysis of excavator working equipment with this technology. In the paper, mock-up solid model of excavator working equipment was established with Pro/ENGINEER software, the kinematics and the dynamics of the model was analyzed with ADAMS software and then the intensity analysis and structure optimization were done with ANSYS software. The conjoint analysis and simulation not only give full play to these three software's advantages, but also realize data sharing and enhance efficiency and precision of the analysis.

Abstract: The 21st century is the new era which mankind develop and utilize the ocean，In order to exploit and utilize of marine resources，the bucket foundation is emerged under this condition. In the process, a lot of marine soft soil materials is inevitably encountered with in engineering practice. Traditionally, the bucket foundation is only a upside-down bucket and no compartment is set inside. Using the finite element method, this paper makes a systematical expatiation on the research on the horizontal bearing capacity of bucket foundation with marine soft soil materials under cyclic loading conditions.

Abstract: This paper applies large-scale finite element software ANSYS and the module of LS-DYNA to establish the solid model of bucket teeth, and according to Smoothed Particle Hydrodynamics Method (SPH) establishes the soil constitutive model. Emulating the process that bucket teeth excavate soil of three different grade ruggedness coefficients obtains the stress and statistical value of bucket tooth point; Simulation results show that: the stress concentration of bucket teeth point is more serious. When the ruggedness coefficient is0.6< f <1.0, the corresponding maximum stress is 197 ~ 309MPa, which meets the strength requirement .The damage is caused by the fatigue failure.
