Title: Variable stiffness analysis for slide beam structures and preliminary considerations in vibration control
Abstract: This paper presents a variable stiffness analysis for several slide beam structures,and the computation formulas for the slide stiffness and the static stiffness of the slide beam strcutures.The relations between the slide stiffness and the static stiffness are obtained,with a comparison of the stiffnesses between the straight beam and the curved beam at the same position.It is shown that the slide stiffness depends on the materials,the dimension and the position angle of the beam.The static stiffness is much different from the slide stiffness,and generally the static stiffness is much larger than the slide stiffness.At the same position,the initial slide stiffness of a curved beam is higher than that of a straight beam.As the angle varies with the beam sliding,the silde stiffness gradually decreases.The stiffness characteristics of the slide beam may be used in the vibration control,and some suggestions for vibration reduction are given.
