Introduction to hyper mesh and Ls-Dyna
 Hyper mesh is a preprocessing software where you divide the model into no. Of
elements and nodes for a solver to apply the mathematical functions on it. If you read
FEM OR FEA you would know the underlying theory behind the practice. Pre-
proceesing is generally used to 'mesh' the model.
 Hyper Mesh is the market-leading, multi-disciplinary finite element pre-
processor which manages the generation of the largest, most complex models, starting
with the import of a CAD geometry to exporting a ready-to-run solver file.
 Mesh generation is the premise of finite element analysis, Hyper Mesh as a high
performance finite element preprocessor, By analyzing the specific example of bearing
gear system, the key problems of geometry cleaning and mesh generation in the
process of finite element preprocessing are studied.

 Ansys LS-DYNA is a general-purpose finite element software solution capable of
simulating complex, real-world problems such as impact and crash related problems in
automotive industries, as well as blade containment, bird strike, metal forming, fluid
splashing, metal cutting, blast and biomechanics in other industries.
 It is a post processing software.
 Application:
 1. Automotive crashworthiness & occupant safety.
 2. Sheetmetal forming with LS-DYNA
 3. Aerospace industry applications
 4. Other applications

Introduction to hyper mesh window

Introduction to Helical Bevel Gears
 Helical gears are similar to spur gears except that their teeth are cut at an angle to the
hole (axis) rather than straight and parallel to the hole like the teeth of a spur gear. The
line of contact between two teeth is not parallel to the teeth but inclined.
 Purpose : Helical gears are used increasingly often as power transmitting gears, since
not only can they carry larger loads because of their lower dynamic load but also their
noise and vibration levels in operation are lower compared with those of spur gears.
 APPLICATIONS : Automotive transmissions, industrial machinery, aerospace, and
robotics.
 Ways to Use Gears:
 1. Speed 2. Force 3. Rotation direction 4. Movement

Procedure for the analysis
 Import the geometry:

 Assign property and materials :

Results
 Von-mises stress or equivalent stress :

Conclusion
 The use of the import function in HYPER MESH AND LS-DYNA definitely has some
advantages. It can help to reduce the time it takes to produce the drawings needed in
the work environment. However, if the individual that has created the imported file
does not receive credit for their work, problems may arise in the future. According to
the basic principle of finite element mesh division, through the good interface between
Hyper Mesh and CAD and CAE software, the geometric model import and modal
analysis are realized, and the quality and efficiency of finite element analysis are
improved.
