چکیده
A compufer software has been developed for the analysis and design of fixtures. This software can lead the designer to the optimal design of the fixturing system , which minimizes the total work done on the workpiece, the fixturing force, rhe deformation index, or the maximum effective stress. The workpiece is modeled as a j linear isotropic elastic solid. The machining forces are simulated by speccving ap-pliedforces acting on part of the surface of the workpiece. Thefixturing system consists of a number of fixture elements, each in contact with the workpiece with specified location and area of contact. A t the interface of contact, Coulomb's law of friction is employed. The boundary conditions at the interface of contact are treated exactly. This computer software system is composed of a finite-element program and a computer graphic program which displays the undeformed and deformed workpiece with hidden lines removed. Three sample problems have been solved and the numerical results are presented in this paper.

H∞ Robust Controller Design and Experimental Analysis of Active Magnetic Bearings with Flexible Rotor System
H∞ controller for active magnetic bearings (AMBs) with flexible rotor system was designed in this paper. The motion equations of AMBs and flexible rotor system are built based on finite element methods (FEM). Weighting function matrices of H∞ controller for AMBs are studied for both the sensitivity and the complementary sensitivity of H∞ control theory. The simulation shows that the H∞ control ...

The stiffness of the workpiece is very important to reduce the errors in manufacturing process. The high stiffness of the workpiece can be achieved by optimal positioning of fixture elements in the fixture. The minimization of the sum of the nodal deflection normal to the surface is used as objective function in previous research. The deflection in other direction has been neglected. The 32-1 f...

In this paper, finding Dynamic Load Carrying Capacity (DLCC) of flexible link manipulators in point to-point motion was formulated as an optimal control problem. The finite element method was employed for modelling and deriving the dynamic equations of the system. The study employed indirect solution of optimal control for system motion planning. Due to offline nature of the method, many diffic...
متن کاملFinite Element Instability Analysis of the Steel Joist of Continuous Composite Beams with Flexible Shear Connectors
Composite steel/concrete beams may buckle in hogging bending regions. As the top flange of I-beam in that arrangement is restricted from any translational deformation and twist, the web will distort during buckling presenting a phenomenon often described as restricted distortional buckling. There are limited studies available in the literature of restricted distortional buckling of composite st...

The geometric errors in the manufacturing process can be reduced by optimal positioning of the fixture elements in the fixture to make the workpiece stiff. We propose a new fixture layout optimization method N-3-2-1 for large metal sheets in this paper that combines the genetic algorithm and finite element analysis. The objective function in this method is to minimize the sum of the nodal defle...
