Based on illuminating the structure, working principle and force analysis of mobile electron radar, the finite element analysis of sheet metal shell is carried out on ANSYS Workbench (AWE) platform. First, the structure of sheet metal shell is simplified, then the 3D entity model and meshing model of sheet metal parts both are established. Secondly, the material attribute, contact type, load and constraints...
As the most critical component of a deep manned submersible, the manned pressure hull provides a safe living space for pilots and scientists under the deep sea pressure and its weight occupies almost 1/3 total weight of the manned submersible. So the pressure hull should be designed to have enough strength and should be as light as possible. However, a comparison of the current available design rules...
Tower crane is broadly adopted in industrial, it is urgent necessary to study the effective means to detect and evaluate the status of tower cranes. May be it is a good way to use finite element software to analyze the tower cranes' status parameters. A parametric modeling program in .NET Environment is proposed to establish a large number of tower cranes finite element models quickly. The program...
Based on 3-RRRRR parallel mechanism, a novel 3-DOF micromanipulator which is driven by piezoelectric actuators has been put forward. From the aspect of micromanipulator, spatial parallel mechanism possesses the advantages of high stiffness, compact structure and so on, and overcomes the disadvantage of small workspace. All the flexible hinges of the 3-RRRRR parallel mechanism are revolute pairs, so...
Strength reduction FEM is one of the main methods to analyze slope stability. Based on the extended Drucker-Prager yield criterion in ABAQUS, the plastic zone along a sliding surface from slope toe to the top is assumed as the flag to tell the slope sliding. And a typical soil slope stability is analyzed with extended Drucker-Prager yield criterion with different section circle of Mohr-Coulomb yield...
In this paper, finite element analysis has been applied on the Phi2.8 mtimes5.75+2.25 m of southern Africa that has been contracted by CBMI Construction Co Ltd. Different contact finite element model as manholes in different position of the twelve clock points are built by using ANSYS parametric design language (APDL). Stress and deformation under the actual condition were presented by calculating,...
This paper presents a structural health monitoring system for monitoring, with reduced visual impact, one historical building structure. The system is based on fiber Bragg gratings and comprises 19 displacement sensors and 5 temperature sensors. All the sensors were custom made according to the monitoring points' characteristics. The results obtained over the first year of monitoring are presented...
