Double horse-head pumping unit is a widely used pumping unit besides the conventional model. However, some components often fail during the service, such as the fracture of walking beam and back horse head. This paper aims to obtain the mechanical performance in key components by the establishment of rigid-flexible coupling multibody dynamics model. Firstly, the geometric model of double horse-head...
In this work, an optimization algorithm is presented for nonlinear analysis of space bar structures. The major character of the optimization algorithm is that the equilibrium state with elastic-plastic large deformation is chosen as the study object. Constitutive law adopts linearly elastic and power hardening model. The objective function is defined. The optimization problem is established for nonlinear...
Based on CT scanning pictures from a volunteer's knee joint, a three-dimensional finite element model of the health human knee joint was constructed including complete femur, tibia, fibular, patellar and the main cartilage and ligaments. The model was validated by comparing with experimental and numerical results obtained from other authors. The pressure distribution of contact surfaces of knee joint...
