STAND FOR vibrodiagnostics elastic system MACHINE

摘要

The utility model is intended for the diagnosis of an elastic system of machine tools.; Technically attainable result is to increase the measurement accuracy, as well as expansion of technological capabilities during diagnosis elastic machine system. This is achieved in that in the stand for vibration analysis elastic machine system comprising elements for harmonic, pulsed random excitation in the elastic machine system further soderzhutsya blocks harmonic, pulsed random excitation in the elastic machine system, whose output is connected to the block input, it is designed for processing signals received dynamic effect on the elastic machine system and plotting, the harmonic or random excitation is provided by nb zoelektricheskogo vibrator, wherein the variable force is generated piezoceramic rings, to which are supplied with electric power, and the change in linear dimension columnar piezoelectric elements through the mandrel, measuring piezoelectric tip and is transmitted to the item of the machine, wherein the magnitude of the static force is controlled by means of strain gauges glued on the deformable portion of the base a piezoelectric vibrator, and the non-conductive housing protects the researcher from the high voltage applied to pezoele cients.
