On the compensation of dynamic reaction forces in stationary machinery
Tobias Radermacher, TU Dresden, IFD, Germany
This paper studies a method for active electrohydraulic force compensation in industrial scale high power applications. A valve controlled cylinder drive moves a mass using the force of inertia to compensate for the reaction forces of an industrial scale process. Two strategies for force compensation are developed and investigated in a demonstrator aiming to significantly reduce the excitation of a 160 ton clamping unit of an injection moulding machine. Results of the different strategies are shown and evaluated. Advantages and drawbacks of the developed electrohydraulic force compensation are discussed.
