文档介绍：APPLYING FINITE ELEMENT ANALYSIS IN STRUCTURAL
DESIGN
The use of Finite Element Analysis for the Structural Engineer is an
important advantage. The design of the structures not only benefit, but may
require the use of this advanced analysis approach. The nature of structural
components involves several concerns and requirements. Safety, reliability,
strength, stiffness, and low cost e in to the picture. Coupled with this,
are the additional design requirements of interference, manufacturability,
and overall function.
Traditionally, classical calculation methods were used as the primary tool for
checking the strength characteristics of structures. Using the classical
calculation methods many times has limitations as to the fit to the design
geometry. By using finite element modeling as a primary analysis tool, the
constraints of creativity are removed. All the requirements can now be
evaluated and several variations of the design concept can be considered.
The model can be used to quickly assess the strength and stiffness, and also
the material usage of ponent.
The following case example involves an evaluation of a transfer feed vertical
post. This piece has been identified as a critical ponent of the
transfer feed. The transfer feed mechanism is a three axis device that
automatically loads a large transfer press that forms outer panels of a car or
van. Having a stress failure of ponent would be catastrophic.
Additionally, the stiffness of ponent is important for accurate
positioning of the panels in the dies.

Introduction
The purpose of this analysis is to analyze the stiffness and stress
characteristics of the Transfer Feed Vertical Post Designs. Two designs were
analyzed and are referred to as the “Existing” and “New” des
