Description
technical field [0001] The invention relates to the technical field of mechanical pendulum movement measurement, in particular to a pendulum movement parameter measurement device, method and system. Background technique [0002] The measurement of the movement parameters of the mechanical pendulum is of great significance to the study of the movement of the pendulum mechanism. Whether the various movement time and oscillation frequency indicators meet the design requirements indicates whether the movement of the pendulum mechanism is stable and free of stagnation. It is a part of the movement test of the pendulum system. an important indicator. The two most important motion parameters are the retracting and releasing time of the pendulum and the vibration frequency of the neutral position of the pendulum. The pendulum is connected to the high-energy actuator through the linkage mechanism. The lowering and recovery of the pendulum, measuring the rotational movement angle and...
