A Method of Determing Dynamic Stability Critical Length of Construction Member

Abstract:

Based on the theory of elastic stability of structure,the calculating formula for dynamic stability critical length of construction member being in lateral resonance under the axial dynamic load is derived in this paper. The influence of different parameters, such as end conditions; rod size; damp force and excitation frequency, natural frequency, rod material, on dynamic stability critical length of rod is analyzed. The paper puts forward some related measures for reducing vibration of rod, and may provide reference values for the design and analysis of engineering.
