Abstract: The purpose of this study was to analyze the dynamic behavior of elevating screw subjected to time-varying excitation. Transient analysis is performed to know the response characteristics under the rated load of elevating screw. The effect of this vibration varies with time as the nut moves. This paper researched the elevating screw and built the elevating screw model with SolidWorks software. Modal analysis is carried out for identifying the natural frequencies and the transient analysis is applied for obtaining displacement, velocity and acceleration depend on time variation.
