Door Seal Pressures with I-Scan®
Soft seal bulb material deforms to produce a seal around the perimeter of a door, window
or structure. Development engineers need a tool to confirm specifications, evaluate
candidate bulbs in target applications, and troubleshoot problems.
I-Scan®
sensors are paper-thin,so they can be inserted into areas of interest, such as over a weld point that
affects contact between two surfaces. The sensors are flexible to roll around a simple
curve, such as a cylinder. On a test bench, as position is advanced, bulb deformation
occurs and contact area grows.
|
 |
The resulting seal pressures are vividly displayed on a
computer screen. Contact area and width across the intended seal is shown. The resulting
movie can be analyzed with I-Scan's powerful graphical tools, stored for future reference,
and exported to other applications. I-Scan is portable, so it can be taken into the field or
to assembly lines for on-site problem resolution.
In the study below, about the same total force is applied to two different door seals. The
3-D pressure display given by the I-Scan, with a 6300 sensor, shows a problem in Fig.1.
The valley in the middle indicates a weak spot in this seal, which represents a leakage path
for air or water. Compared to Fig. 2, which has lower peak pressure, and a more even
distribution, making it the more effective design. |
