R. Hecker et P. Schroder, USE OF MECHANICAL AND ELECTROMECHANICAL E FFECTS IN MEASURING ELASTIC-WAVES IN RODS, TM. Technisches Messen, 62(11), 1995, pp. 432-439
Measuring methods for measurements of elastic longitudinal waves in ro
ds are presented. In this connection, it is concerned with two sensors
taking mechanical values and three sensors measuring the mechanical w
ave parameters meters with the help of electromechanical effects using
electrical or magnetic methods. It is shown, that additional system p
arameters can be obtained from measured variables by relations of elas
tic wave theory. Of practical importance are the wave measurements in
tools of percussive machines and in impact stressed building component
