Optimization of screw nut mechanism to use of transportation systems and dynamic analysis of the system

This study investigates the design parameters of the screw and nut mechanisms have been studied to address problems arising from the use of vertical transport platform. Screw nut mechanism modelling parameters has been examined how they influenced each other. For this purpose, the design parameters defining equations transferred to a computer program and variations were generated. A drive system's screw nut mechanisms which is being used in the market are modelled with computer aided program. Finite element analysis was conducted on the model given reference loads. Static and transient analysis was performed. The results obtained from equations and analysis was evaluated. It is given recommendations for improvement for systems from different angles, based on resulting chart. Helix angle, rated load and the shaft diameter of mechanism changed in order to increased speed of the comfortable as a platform has been determined.
