    摘要： The invention relates to testing apparatus and respective control circuit means, especially for testing samples including movable elements such as vehicular axles with the respective wheels wherein load applying means, such as piston cylinder means are arranged to apply loads to a load application point of the test sample whereby the load applying means are controlled by error compensated control values. The rated displacement value or the actual displacement value of a first load applying means is supplied as a compensation or correction value to the control circuit means of one or more load applying means through a computer which calculates the correction or compensation value as a function of a curve which represents the displacement of the load application point and which displacement depends on the geometric configuration or structure of the sample to be tested.

    摘要： The present peak value measuring and regulating circuit arrangement includes at least one maximum signal memory and one minimum signal memory for storing oscillation representing signals for a constant length of storage time (t1) during which logic circuit means controlled by the upper signal value or by the lower signal value actuate a timer which closes signal path means to supply either differential signals or actual signals representing certain load conditions to evaluating and regulating means for an evaluating time duration ( Delta t) which is independent of the frequency of said oscillation. At the end of the storage time (t1) the timer erases the stored information.

    摘要： The present valving mechanism forms part of the load piston cylinder means, for example, of a hydraulic testing apparatus. The load cylinder is provided with a first control inlet at each end thereof and a second control inlet substantially at each end of the resonant stroke of the piston. Storage means are connected to the load cylinder also substantially at each end of said resonant stroke. Further, control ring pistons are slideably arranged on the piston rod on each side of a piston which is fixed to the rod. The control ring pistons close or open the ports to said storage means.
