Abstract:

The dynamic stress caused by vibration when construction hoist is working may cause the structure damage, so the dynamic analysis is an essential part in the design of construction hoist. This paper establishes a dynamic model of construction hoist by ANSYS, then conducts modal analysis, and gets the first 6 natural frequency and vibration modes.

I. Introduction

Construction hoist is an essential vehicle in building operation. Along with the development of the technology and economy, skyscrapers are emerging one after another. The demand for construction hoist increases greatly. At the same time, the safety of construction hoist is also put forward higher requirement. The enormous dynamic stress caused by the dynamic load which is produced when construction hoist is working may damage the hoist. Dynamics analysis is usually divided into two parts: the modal analysis (i.e., solving the natural frequency and the vibration mode of the system) and the dynamic analysis at certain loads. This paper sets up a dynamic model of SC200–200 type construction hoist by ANSYS, conducts modal analysis, and gets the dynamic characteristic parameters: the first six natural frequency and vibration modes. The results provide the reference for the structure optimization design and the vibration stability analysis of construction hoists.
