STAND FOR STUDYING THE OPERATING CHARACTERISTICS OF MARINESCU OSCILLATORS

摘要

The invention relates to a stand for studying the operating characteristics of oscillators. According to the invention the stand comprises an oscillator supplied from an alternating voltage source with adjustable frequency and duty factor carrying out the conversion of vibration motion into a continuous rotation motion, the conversion being carried out by means of a mobile armature (1) subjected to a reciprocal motion generated under the action of a magnetic field produced by some stator windings (2 and 2') where the mobile armature (1) is mounted on a mobile rod (3) which slides on two guides (4 and 4') and which has a tensegrity structure (5) provided at one end, said tensegrity structure (5) being integral with a disc (5'), by means of said structure the reciprocal motion being transmitted to a disc-shaped rotor (6) which in its turn is coupled, by means of some elastic couplings (7, 7' and 7"), with a mechanical torque transducer (8) which furnishes at the output a voltage (U) proportional with the mechanical torque, with a mechanical load (9) and a tachogenerator (10) which furnishes at the output a voltage (U) proportional with the speed of the rotor (6), by means of which it is possible to determine the mechanical characteristics of the oscillomotor.
