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 this type of systems from different perspectives, based
on resulting chart.

Anahtar Kelimeler
