WM877 Heavy-duty components 60 tons

Figure 1: 60 tons component in preparation for the application MEMV®
The aim of MEMV 2018 test: 1. Test rubber pads 2. Strengthen influence rubber to the vibrations 3. Attenuation at which crushing factor information
How important the rubber pads are, showed the 64 tons component. The load statement: We have 16 rubber placed Load as an end stop (impact load) - the time (max.): Fmax = H × 0.50 Load as an end stop (shock) - rare (max.): F max = 0.60 × H Continuous load - static (max.): F max = 0.15 × H Vibration damping: fmax = H × 0.05 to 0.10 × H

Figure 6: Raise this component was not easy.
Figure 7: The WIAP V vibrator was mounted in a location with greater elasticity. Clamps hold far too little.
Figure 8: This is where the 60% of the rubber bruise was reached, more should be avoided.
Figure 9: Here the uneven surface has overstretched the rubber, even though we had a lot of rubber. If a job is deeper when lowered, it exceeds the yield strength of the rubber and damaged it. Here we must because more large-scale rubber inserts under metal support plates.

Figure 10: The WIAP V stimulator must be well secured. If the component is moved in the resonance zone, you think you sitting in a guitar. A very intense, loud sound. Not infrequently 90dB be exceeded. However, good clamping is, if the component moves to 50G, but almost no dB can be seen.
Figure 11: This small V stimulator can bring about 60 tons to fury the component. Almost unbelievable. But the controlled speed can be much more.
Figure 12:
Figure 13: The component is connected to the stimulator. To tighten unedited on clamping points, we need to use support pins against the "walking".
Figure 14:
Figure 15: Enormous quantity of welds gives the member strength. 4 x M24 with just under 72 tons, was needed.
Here is some information about rubber:
Metal expansion plant WIAP MEMV® Rubber documentation system
Single rubber system
Best resonant attenuation results when pinching between 5 to 10%
Heavy system, single rubber system 3 x 1 pcs. small or large pcs. 2 x 1
Here is the table with the elastic modulus
