Estimation of point loads on a span for a vibrating pipe has been done with the help of boundary measurement of slope data. The approach is based on the theory of inverse force identification for hyperbolic systems. Depending on the form of the forcing function, which also satisfies some continuity conditions, an exact determination is possible. Though restrictive in its formulation some applications are still possible. A typical case for harmonic excitation of a pulsating reciprocating compressor has been shown as an illustration.
