Performing the remaining mechanical tasks and practical tests

Completion of Pending Tasks

In this second phase, the following remaining activities were completed:

• Application of non-slip surface (2mm EVA) on all three platforms.
• Inserting the Platform Supports in one of the three units.
• Carrying out openings extras for cable routing and ventilation in the tower.

Fixing Materials and Methods

• Cable holes: 10mm diameter drill, ensuring sufficient clearance for harnesses and ventilation ducts.
• EVA attachment: instant glue (cyanoacrylate) applied between one side of the EVA rubber and between one side of the platform, with uniform contact for maximum adhesion.
• Fixing the plastic supports: 3M VHB double-sided tape, chosen for its high rigidity and possibility of repositioning without damaging the plastic support or MDF.
  • The use of super glue to attach the supports to the MDF platform would undoubtedly increase their rigidity but would drastically reduce their maintainability, as if it were necessary to remove the support from the platform it would be very difficult to do so without breaking the support. The use of 3M VHB double-sided tape proved to be very efficient, we will comment more on this below.

Single Platform Dynamic Load Testing

• Procedure: repeated jump (10 common jumps, 10 jumps bending the knees) performed on only a single fully assembled platform. In other words, twice the force that would normally be applied was applied.
• Notes:
  • 70kg jumper;
  • Jump performed barefoot;
  • There was no displacement or loosening of the supports;
  • Absence of noises (creaking, clicking) that would indicate failure or fatigue;
  • There were no problems with the feet contacting the platform (sliding, feeling of instability);
