The multicomponent dynamometer which converts the loads acting on it to a corresponding electrical signal is one of the main elements in strain-gauge force-measuring systems. Recently, the requirements for accuracy of these information-measuring systems have grown along with the area of their application thereby necessitating improvement in existing dynamometers and development of new design diagrams. The working efficiency of the straingauge dynameter designer is determined to a significant extent by the resources at his command for estimating the output signals of, not only the measured forces and moments, but also external actions like centrifugal and friction forces, temperature, etc. For instance, the effect of centrifugal forces in rotating dynamometers has to be accounted for in developing the design diagram. The effect of thermal loads is often considerable. Rigid requirements on maximum permissible displacements and angles of rotation are imposed on some dynamometers. In selecting the design diagram and its geometric dimensions, we have to seek a compromise between the contradictory requirements of maximum rigidity of the dynammometer and its sensitivity which is inversely proportional rigidity. All these problems make the design of these dynamometers, especially multicomponent types, a complex and lengthy task.
