"With COSMOS, we were able to
quickly reduce the size and weight and increase
the stiffness of this part as well."

The Challenge
The Johnson Corporation provides advanced process control
systems, rotary joints, syphon and heating systems, and related
components for fluid and heat transfer equipment that is used
in process industries. Diverse industries such as pulp & paper,
steel, plastics, textiles and rock quarries-companies requiring
a rotating cylinder or drum that must be heated or cooled-rely
on Johnson. "We are often called upon by our customers to
adapt one of our products to their special needs," says Alan
Ives, Director of Product Development at The Johnson Corporation.
"We must have the ability to do this quickly, with excellent
and predictable results."
Recently, Ives and his team were challenged
to optimize the design of a rotary joint and syphon assembly that
is used in the dryer section of high-speed papermaking machines.
Refining an already solid design using hand calculations and existing
FEA software, however, would have been too time consuming. Without
a new engineering solution, the project would have taken substantially
more time, with less return on the design investment.
The Solution
Johnson used COSMOSWorks to analyze the stresses in each of the
component parts. COSMOSWorks allowed the Johnson engineers to
analyze these parts and track more concepts in a shorter period
of time with fewer design iterations. The result was an assembly
that was stronger, lighter, and more durable, and it was developed
in a fraction of the normal development time. "We found COSMOSWorks
to be a very robust package. It helped us achieve all of our design
objectives, on schedule," Ives relates. "Without COSMOSWorks,
we would have used an older FEA package, one that was much slower
and, by comparison, more cumbersome to use." After using
COSMOSWorks on this project, engineers at Johnson now use COSMOS
software on the design of new products as well as on the enhancement
of existing Johnson products.
Summary and Metrics:
- A 100 mm size body was reduced in weight from 55 kg to 34
kg
- The 89 mm syphon support tube decreased in weight from 48
kg to 27 kg
- The ring bracket weight was reduced by one-half.
- Accurately predicted real world behavior of the model

"There
was a substantial reduction in weight between the previous
design and the new design. That reduction is a direct
result of using COSMOSWorks to optimize the design. We
would not have been able to achieve as much of a reduction
using hand calculations."
