Vertical and horizontal gantry crane dynamic stiffness

Vertical and horizontal gantry crane dynamic stiffness Ge-Ning Xu . Tsui Hark Jin ( Department of Mechanical Engineering ) Abstract gantry cranes for different types of vibration analysis conducted research , presented a series of practical formulas gantry crane vertical and horizontal dynamic stiffness , add a calculation method static and hoist gantry crane dynamic stiffness , expanding the door crane static , dynamic stiffness range checking for gantry crane characteristics and analysis of existing research data , it is recommended that the static and dynamic stiffness control value for the realization of dynamic design gantry crane has created favorable conditions . Keywords gantry crane , the dynamic stiffness of the CLC TH2; TU390 Introduction gantry cranes (the door ) is an important Lifting Equipment Yard steel crane national economic departments , warehouses and assembly plant widely used , it can be divided into single girder trolley hoist gantry crane and standard double girder gantry crane trolley two types , with the corresponding divided into single and double girder gantry girder gantry two structural types ( Figure 1 (c), 1 (e) and 1 (d)), divided into a leg frame (Fig. 1 (c), 1 (d)) and L (Fig. 1 (e). door according to the size of the span。
