Description
technical field [0001] The invention relates to the technical field of mechanical pendulum rod motion measurement, in particular to a pendulum rod motion parameter measurement device, method and system. Background technique [0002] The measurement of the motion parameters of the mechanical pendulum is of great significance to the study of the motion of the pendulum mechanism. Whether the movement time and oscillation frequency indicators meet the design requirements, it indicates whether the motion of the pendulum mechanism is smooth and without stagnation. It is a part of the motion test of the pendulum system mechanism. important indicator. The two most important motion parameters are the retraction and release time of the pendulum rod and the oscillation frequency at the neutral position of the pendulum rod. The pendulum rod is connected to the high-energy actuator through the link motion mechanism, and the high-energy actuator is pressurized and relieved to realize the ...
