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...
Ultra-precise positioning platform plays a significant role in ultra-precise operation and micro-operation. A new compliant 3-DOF spatial translational ultra-precise positioning platform is proposed and it overcomes the shortcomings of the general conventional drive and transmission such as low speed of response and low displacement resolution. The platform is consist of flexible hinges which provide...
A method of lightweight design based on material selection and structural optimization is developed for engine hood inner panel. Introduced the decision-making mechanism of multi-objective satisfaction degree to lightweight material selection, built the model of finite element analysis and computer experiment analysis of the strength, stiffness and modal properties respectively to the different lightweight...
The mounting bracket is one of the most important connecting components in commercial vehicle cab. The FEM provides guidance for maximizing the effectiveness of weight reduction efforts on condition that the structure meets the requirements for strength, stiffness and vibration performance. The work presents two kinds of structural optimization methods, which are topology optimization and size optimization...
The research of autobody lightweight technology is an important mainstream in the autobody design. In this paper A FEM model for the unitary body of a home-made bus is established .Then optimization design variables are determined through stiffness sensitivity analysis and by using finite element analysis software, an optimization is conducted, based on which a lightweighting scheme is put forward...
The composite steel frame-reinforced concrete infill wall structure is considered as a new type of earthquake-resistant system with brilliant future of application. In order to study the hysteretic behavior of the structure, a large scale specimen under cyclic load was conducted and then the computer simulation models were established using the software ANSYS. By comparison, the computer calculated...
In contrast to conventional drives, with direct drives the motor is not created until it is integrated into the machine. The mechanical and electrical subsystems are merged to form the mechatronic system by the velocity and position control loops. Since control parameters have a crucial influence on the behavior of the complete system, a main goal of this article is to explain their importance for...
