| 128 - Structural Analysis of a Cantilever <DS> |
Overview
Closeup |
The importance of strength design for devices is growing with the miniaturization
and flattening of electrical equipment and measures to reduce vibrations
are in even greater demand.
To understand the characteristics of electrical equipment, the vibration
characteristics and strength of each part that make up the device need
to be accurately evaluated. Therefore, the phenomenon of each individual
part needs to be correctly analyzed first.
This example presents the use of a structural analysis to obtain eigenmodes
and displacement that has a concentrated load for 3 types of mesh models
of a simple cantilever. These results are then compared to the theoretical
values. |
Eigenmode
The first eigenmode for model A with a course mesh using the primary element,
model B with a fine mesh using the primary element, and model C with a
course mesh using the secondary element are indicated in Fig. 1. The first
through third eigenfrequenies are indicated in Table 1.
The direction of deformation can be evaluated for the first eigenmode even
with a course mesh, but a finer mesh needs to be generated, or the secondary
element needs to be used to bring the results to approximately 5% when
compared with the theoretical values of the eigenfrequencies including
bend.

Displacement
The displacement in the Z-direction of models A, B, and C are indicated
in Fig. 2, and the maximum displacement is indicated in Table 2.
Just as the eigenmode, the deformation can be estimated even with a course
mesh, but a finer mesh needs to be generated, or the secondary element
needs to be used to bring the error of the results to approximately 5%
when compared with the theoretical maximum values including bend. |
