Developed
for VOLVO in 1999. | By Dr. Stepan V. Lunin. | Development
cost: 1400 hrs.
 This
software was the most advanced spiral bevel gear software
of the 20-th century. Even today it is still the only
spiral bevel software that can simulate generation
of a complex tooth form and a high resolution contact
pattern. The mathematics of the software is based
on the Dr. Lunin’s Direct Digital Simulation Method.
that was incorporated with numerous mathematical tools
for higher calculation performance.

VOLVO
used Gleason software but the production of new advanced
gears required more advanced calculation tool that Gleason
or Oerlikon could not offer. 
VOLVO
spiral bevel gear software is capable to simulate the
geometry of any tooth form. The input options allow
to select a common cutter geometry or input the cutter
geometry from the file of x,y co-ordinates.
The
generation process can be visualized in 3-dimentional
window so you can see how the material is removed
from the gear blank.
The
software has an extended 3-dimentional-visualization
module similar to common CAD programs. The final contact
pattern can be visualized in 3-dimentional window.
The
window can show instant and integrated contact pattern.
It can also show animation of the contact pattern during
the rotation of the gears.
You
can easy misalign the gears and see how the contact pattern deviates
from the nominal position.
The
program also provides the transmission error for each tooth.
The
program calculates the friction and load for each individual point
on the tooth surface in order to provide accurate data for driving
efficiency calculation.
The
program was used for design and development of advanced not involute
gears.
