Flame straightening Information 02 Metall stress relief with vibration

Inquiry as vibration neutralization zone / G dead centers / accounts points /
A 12 meter tube has 4 vibrational neutralization zone respectively G Todpunkte or nodes
Figure 1: Pipes MEMV relax
Figure 2: 18 pieces 350 x 250 tubes of 16 mm in wall thickness, hydraulic and flame-related components, we have MEMV®_ relaxed.
Figure 3: Technical data sheet of the pipe delivery
Figure 4: The first neutralization point is at 1200mm
Figure 5: The second neutralization point is at 4000mm
Figure 6: The Third neutralization point is at 7800mm
Figure 7: The fourth neutralization point is at 11000mm. The axis of rotation of the fixed point is in a clockwise direction.
Figure 8: The whole tube is 12,200 mm long. So these four neutralizing points are outside of both sides always at 1200 mm and from both sides from the outside at 4000 mm. Why and how it behaves in various constructions are we determine on. If we get a point, if we put the stimulator, it is obvious that we can obtain no real stress relief, so the Aufsetzpunk the exciter should be avoided.

Figure 9: Here we examined the difference at a measuring point when we deal with 0 degrees or 45 degrees MEMV®. The neutralization point remains in both directions at the same location
The information on the workpiece are measured with the measuring pin G, that is for example 31 = 3.1 g. Interesting. The distance from measuring point to measuring point was 100 mm 200 mm is within the neutralization point to the zone where we take place quite a strong deflection. And this situation we have at four places of the pipe.
Figure 10: Here we have instead five rubber 10 rubber with a pipe down to see if the vibration neutralization zone due to the rubber migrates number. The vibration neutralization zone does not migrate, in both species, the points remain fixed in the same place, unchanged.
Figure 11: Here is the test with 10 rubber neutralizing points remain unchanged at 5 and 10 rubber.
Figure 12: Here, the stimulator is set for the excitation of X / Y and Z axis, say the 45 ° axis direction arrangement.
Figure 13: Here, the stimulator is set for the excitation of Y and Z axis, say the 0 ° arrangement Here we give no excitation energy in the X axis. That's Reported according to the protocol.
13: 18 pipes tested, and several additional test done by more clues for further investigations to be able to carry along.
The more we measure and calculate, we realize that:
You will end up Metal relax with vibration over, when components are addressed, or if the manufacturing processing high
It takes the tension arm glow that is not replaceable. but it also needs the metal relax with vibration. The MEMV® system.
Both methods used in the right place a better more accurate cost-conscious allow production. Both methods have different tasks.
