In order to prevent
leakage of fluids from the filter, engineers had to
redesign the central hole in the cap of a Nelson steel
oil filter used in a diesel powered truck.

The Challenge
Fleetguard®, Inc., with headquarters in Nashville, Tennessee, is
the leading worldwide designer and manufacturer of filtration products
and exhaust systems for heavy-duty, diesel-powered equipment. Fleetguard's
comprehensive product line includes 6,000 filtration products, 5,000
exhaust products and 1,000 custom maintenance kits. These products are
used in heavy-, medium- and light-duty trucks, industrial equipment
for construction, mining, agriculture and marine applications, and power
generation.
Nelson engineer Tao You needed
to find a way to redesign the central hole in the cap of a Nelson steel
oil filter used in a diesel powered truck, in order to prevent leakage
of fluids from the filter. To prevent leakage, he needed to reduce the
displacement of the center hole, so the rubber grommet that was part
of the filter would not slip through the hole.
There were a number of ways
to approach the task. He could increase the thickness of the material,
to see what effect that would have on leakage. He could change the cross-section
shape, to try to reduce the deflection. Or he could make a ring dent.
The Solution
With COSMOS, You was able to complete the analysis of a variety of solutions
in several hours, testing the effects of 150 psi of liquid pressure,
using the same boundary condition. Use of COSMOS saved days of analysis
and model construction time.
"COSMOS helped me see
that there were two viable solutions to choose from-doubling the thickness,
or designing a ring dent. It was less costly to double the thickness
of the material, so that was the solution I chose. This solution showed
much less deformation than the original design."
Summary and Metrics:
- Completed analysis in several hours instead of days.
- Tested a variety of solutions of the effects of 150 psi of liquid
pressure, using the same boundary condition.
