Analysis and Redesign of a Portable Stand

Abstract

Stands used in stadia and sports arenas are usually fixed as a part of the civil work. There is a need for portable stands for an event like concerts, outdoor play and entertainment event for which construction of non-portable stand are expensive. Even compact stadium used in University and academic institutions are multi-purpose for which non-portable stand takes a valuable space. There is a need for fold-able stand which can be stored remotely and installed quickly on occasions when events are staged. A fold-able portable stand was fabricated using SS202 (Stainless Steel) material. The aim of the present study is to improvement and validation of the structural design for portable stand. The design was analyzed for structural strength for the requirement of seating capacity. The structure was analyzed under experimental loading conditions and its behavior simulated in CAD using Pro-Engineer/CreoParametric and ANSYS 14.5 software. Validation of the simulation was done against experimental results. The critical stresses observed at joints were analyzed by simulating the joints as a kinematic member and validated through loading experiments as fabrication of only the joints.
