A power mode approach for estimating power transmission between a stiff source and flexible receiver

A power mode approach for estimating power transmission between a stiff source and flexible receiver
In this paper a power mode approach to estimating the power transmission between a stiff source and flexible receiver is reviewed. Previous applications have considered the cases whe re only translational coupling degrees of freedom exist, and these are uni-directional. Here this approximate approach is extended for more general cases where there may be multi-directional and/or rotational coupling degrees of freedom, e.g. the power transmission may have contributions from coupling forces and moments. A matrix scaling technique is introduced. Then, three new approximate expressions are described for the upper and lower bounds and the frequency average of the power transmission. The advantage of this approach is that the amount of data required is substantially less than that of an exact description. Numerical examples are presented concerning a force/moment excited beam-plate system.

Abstract

In this paper a power mode approach to estimating the power transmission between a stiff source and flexible receiver is reviewed. Previous applications have considered the cases whe re only translational coupling degrees of freedom exist, and these are uni-directional. Here this approximate approach is extended for more general cases where there may be multi-directional and/or rotational coupling degrees of freedom, e.g. the power transmission may have contributions from coupling forces and moments. A matrix scaling technique is introduced. Then, three new approximate expressions are described for the upper and lower bounds and the frequency average of the power transmission. The advantage of this approach is that the amount of data required is substantially less than that of an exact description. Numerical examples are presented concerning a force/moment excited beam-plate system.
