Abstract

The characteristics and usage of the non-dimensional damping coefficient Co have been studied in this paper. It's made possible to estimate the damping performance regardless of the specification by using the parameter Co.Because the parameter Co is dimensionless, the specification of the structure is irrelevant to estimate. The vibration test using structure models and the numerical simulations were carried out under different kinds of conditions. The theoretical verification was carried out using the results for the characteristics of the parameter Co. At the result, the following was revealed.1) The universal relational expression is established between the Co and response reduction ratio. Despite changes in the size and structural specification, not affected, this relational expression is true universally.2) The universal relationship is established between the dynamic parameter M, K, C and Co. As an example, consider the two structures of different sizes and structural specifications. By using this equation, it’s possible to adjust the damping characteristics will be the same as that between the two structures. The method has been shown in this paper.
