Modal finite element correlation for Computer Aided Engineering
Education.
Abstract
The main challenge faced by many mechanical engineering educators is the
implementation of real solutions during their courses. One alternative
can be a project-based learning, where the students can be engaged in
the development and analysis process currently applied in the industry.
This kind of teaching process not only can be used to improve the
quality of teaching-learning process but also the students can have
opportunities to solve real engineering problem. This paper therefore
reports a project-based learning implemented in mechanical engineering
courses given in bachelor´s and master’s degree. The component under
evaluation has been selected considering the student’s interest, this
criterion was also taken to involve several students into a real project
process to their learning development. During the semester have been
delivered activities to solve the same problem using different
approaches based on student´s skills. This procedure can be replicated
for students and teachers by following steps. To begin this process, the
first step is present the theoretical basis for modal analysis. The
second step is to apply theorical knowledge to structure a numerical
finite element model. Then, it is used Hypermesh, Optistruct and
HyperView software to solve and simulate. The final step was to perform
experimental using a three-dimensional scanning vibrometer on 60
samples. It is well noted that the implementation of engineering
software commonly used at the industry would increase students’
confidence. This allows students to perform real problem-solving
activities to develop outcomes as establish goals, plan task, meet
deadlines. Therefore, this paper shows an engineering solution process
to provide a learning alternative to teach the modal finite method
solutions correlation with experimental solutions.
