摘要： Provided is a multifunctional grade separation bridge without traffic lights at a crossroad, including a transverse main road, a longitudinal main road, a central circular flyover, exclusive right-turn lanes, non-motorized vehicle lanes, and underground pedestrian passages. The longitudinal main road is laid on the ground. The transverse main road passes below the longitudinal main road in a manner of U-shaped tunnel. The central circular flyover is located at an uppermost location of a center of the crossroad. A lane passage electronic indicator screen is arranged above each of entrance lanes of the central circular flyover, so that functions of going straight, turning round, turning and turning right of the central circular flyover are enabled or disenabled through the lane passage electronic indicator screen in real time according to a traffic flow situation. The grade separation bridge is simple in structure and beautiful, separates people from the vehicle with no interference in each direction, has no need to set traffic lights, and can implement the obstacle-free and fast passage of pedestrians and vehicles, thereby effectively increasing the traffic flow at the crossroad and reducing the passage time.

摘要： The present invention discloses a method and system for measuring a micro—amplitude vibration of a thin—walled part based on motion amplification and optical flow tracking, and belongs to the technical field of micro—amplitude vibration measurement of thin—walled parts. The method mainly includes: obtaining a target vibration frequency based on a brightness change; processing a grayscale image series by using a phase—based Eulerian method to amplify a vibration magnitude; processing a video after motion amplification by using an optical flow tracking algorithm, extracting a vibration signal of a target corner in pixels, and compensating for an attenuation; and establishing a mathematical model for measurement, and converting the vibration signal in pixels into a vibration signal in an actual unit. The present invention combines a phase—based Eulerian amplification method with the optical flow tracking method to effectively solve the problem that the Nacro— amplitude vibration of the thin—walled part cannot be measured, and has the advantages of convenient operation, high spatial resolution, non—contact, and 'visual micro— vibration, etc.

摘要： Disclosed are a large-diameter crown-shaped impactor for crushing hard rocks and a crushing method using the same. Gas is intermittently introduced into the impactor through a 5 planetary gear train. By optimizing installation positions of a plurality of drill bits, auxiliary drill bits other than a main drill bit intermittently work to improve the transfer efficiency of impact energy. Compressed air is introduced from the transmission shaft to a guide sleeve through a cavity of a support base under the operation of the gas distribution blocks. The guide sleeve is communicated with the main drill bit and the compressed air is continuously 0 supplied to the main drill bit. When the gas distribution blocks are communicated with through holes on a drill bit mounting plate, the compressed air enters the auxiliary drill bits to realize gas distribution in cycles. The impactor of the application is supplied with gas intermittently and is designed with the crown-shaped structure to greatly reduce the working noise. During the working process, gas is introduced into the impactor of the application at 5 intervals, so that the auxiliary drill bits other than the mail drill bit work intermittently, thereby avoiding the damage to the rotational structure of the drill bits caused by the failure of the hitting, so as to improve the service life of the drill bits. 76 it a 2 3

The present disclosure has the benefit effects that the present disclosure may accurately localize the damage position and identify the damage degree only by establishing a certain type of wind turbine blade and measuring the inherent frequency of the online blade by means of a sensor, and that localization method is simple and efficient.
