Moving Tower
Design Feasibility Analysis

Conclusion
The project was done to study and assess the design feasibility of the proposed moving tower structure and finally come out with a mechanism which will successfully accomplish the independent rotation of each sections of the tower along the inclined planes. Further, using a CAD model analysis, various studies were conducted and a conclusion was reached that designing a moving structure is feasible through careful engineering. Once feasibility was ascertained we developed a CAD model of the structure which was based on the initial conceptual dimensions but was strong enough to resist both static and dynamic loads. And was concluded that driven drive mechanism although the cost is more could be more efficient and would consume less power than the gear transmission mechanism.

Objective
The Moving tower was designed by National Institute of Design (NID). The tower is designed as a tourist attraction such that each floor can rotate along an axis perpendicular to the mating planes. The highlight of the tower is that it can achieve various shapes as per the input given by tourist visiting the tower. The tower is not meant to be occupied and it can only be viewed from outside. It would be a beautiful spectacle when the tower achieves different shapes. The design of the tower is inspired from the traditional Indian designs of temples and towers. Its shape has reminiscence of the curve in Indian temples and the structure of towers like “Qutub Minar. The main objective of this project is to do engineering of this proposed design and to arrive at the cost estimation of the project. In this study two possible mechanisms were proposed and their corresponding engineering details and cost estimates were provided.
Design Analysis and Cost Estimation
The tower is 25.2 meters high with 6 floors. Each floor has an inclination of 15° angle in the mating surfaces with respect to the mating surface below. The tower is designed such that each floor can rotate along an axis perpendicular to the mating planes. This rotation provides various shapes to the tower. Two mechanism of gear transmission mechanism and the direct drive mechanism which has their own advantages and disadvantages were proposed for achieving the design .Design of the structure of each floor were carefully analyzed and “prat truss” design which has vertical beams for compression and horizontal beams to respond to tension was proposed. Stainless steel (SUS 301 L) which has sufficient strength and can withstand the varying weather was proposed for the construction of the tower. Using FEA analysis maximum stress and deflection at each floor of the tower were calculated and plotted. The cost of the complete project was presented for both the mechanism and it was found that gear transmission mechanism costs less than the direct drive mechanism but the direct drive mechanism was suggested as it would consume less power and would require less maintenance.
