DEVICE FOR DEMONSTRATION AND RESEARCH forced oscillations with inertial perturbation

摘要

The invention relates to educational and research equipment at the theoretical mechanics and is a device for display and study of forced vibrations of a mechanical system with an inertial disturbance. It comprises a base, a carriage, a spring-loaded relative to the base, the mechanism of excitation of oscillations of the carriage comprising an electric motor and gear mechanism with a rod, power supply unit and registers the position and the carriage mechanism. The essence of the model is that the excitation oscillation mechanism is mounted on the carriage and provided with a rack and a pendulum connected to the rod, and recorders are designed as sensors of angular deviation of the pendulum and the movement of the carriage. The device is provided with a unit recording and processing of sensor signals, deviation of the pendulum sensor is designed as a potentiometer, a sensor of the longitudinal displacement of the carriage - in the form of the ferromagnetic rod and the induction coil, but as a recording and processing unit PC applied. The utility model can improve the information content, reliability and accuracy of the demonstration and study the characteristics of the oscillation. 2 ZP Formula 5 Fig.
