Dynamic track based on acoustic measurement and electrical control and constant-speed regulating method

Abstract

The invention discloses a dynamic track based on acoustic measurement and electrical control. The dynamic track is characterized by comprising a sloping plate track, a base and a trolley, wherein a longitudinal hole which is parallel to a driving straight line of the trolley is formed in the sloping plate track; a longitudinal notch which is communicated with the longitudinal hole and parallel to the driving straight line of the trolley is formed in the surface of the sloping plate track; the bottom part of the trolley is provided with a connecting arm which stretches into the longitudinal hole from the longitudinal notch; the lower end of the connecting arm is connected with an acoustic generator; the direction of the acoustic generator is parallel to the driving straight line of the trolley; the end head of the longitudinal hole in the direction of the acoustic generator is provided with an acoustic receiver; the receiving end of the acoustic receiver is opposite to the acoustic generator; a position, which is close to the rear end, of the sloping plate track is hinged to the base; the starting end of the sloping plate track is connected with the base through a height regulating mechanism; the height regulating mechanism is connected with a driving motor; the driving motor is connected with a controller. The dynamic track disclosed by the invention has the advantages that the trolley is kept in constant motion, the motion obtaining speed is fast, time and labor are saved, constant features can be simulated, the quality is high, the acoustic wave guidance is good, and the transmission quality is high.

Description

technical field [0001] The invention relates to a dynamic device, in particular to a dynamic track based on acoustics and electricity. Background technique [0002] In dynamics research, it is often necessary to obtain an ideal trolley moving at a constant speed, but the plane on which the trolley walks and the wheels have frictional resistance, so researchers often use slope tracks to overcome the frictional force by using the component force generated by the trolley's own gravity. to simulate a smooth track. When in use, place the trolley at the beginning of the sloping track, change the inclination, and search for a uniform inclination. In order to obtain a suitable inclination angle, the researchers need to adjust the inclination angle of the slope, measure whether the moving speed of the trolley changes, and if it changes, continue to adjust the inclination angle. There are following deficiencies in the prior art: [0003] 1. Theoretically, it is impossible to obtain...

[0004] 2. Do not allow the car to adjust while moving

[0006] In short, in the existing technology, the quality of the uniform motion of the trolley is not high, and it still needs to be improved and perfected.
