The invention provides an exoskeleton mixed control system and method for a lower limb walking assisting machine. The system comprises a track generation module and the like. A master controller module comprises a high impedance controller module and a self-adaptation control module. The track generation module generates lower limb exoskeleton joint track information and guides the lower limb exoskeleton joint track information into the master controller module. A position and speed feedback module collects position and speed information of joints of exoskeletons and feeds back the position and speed information to the master controller module. An FSR circuit module detects the contact force information of soles and the ground through FSR pressure sensors installed at the soles of the exoskeletons and sends the information to a controller decision module in the form of voltage. The controller decision module judges whether the leg swinging period exists or the standing period exists according to the voltage information and sends the judgment result to a 51 single chip microcomputer module. The exoskeleton mixed control system and method are feasible, and the control effect and user experience of the machine exoskeleton system can be improved through mixed bottom layer controllers.

The invention relates to an ultrasonic phased array detection system for a transitional circular arc inside a cavity. The system comprises an ultrasonic phased array detector, a detection probe and a positioning device. The system is characterized in that a probe propelling device consisting of an auxiliary operating frame, a balancing weight, a probe clamping block, a fine steel wire and the like is designed. The ultrasonic phased array detection system for the transitional circular arc inside the cavity provided by the invention has the advantages of: 1, ensuring that the centre of curvature of an arc-shaped wafer of the detection probe is concentric with the circular arc detected so that an ultrasonic wave is vertically incident to corner parts of the circular arc detected so as to realize detection with high sensitivity of all parts of the circular arc; 2, ensuring that the probe operates stably in the cavity structure clings to the side wall of the circular arc detected; 3, ensuring coupling of detection by forming a sealed water cavity between the detection wafer of the probe and the circular arc detected through the detection probe and the front and back clamping blocks; and 4, precisely positioning the movement position of the detection probe through the probe positioning device so as to position the defect horizontal position precisely.

The invention provides an ultrasonic vibration device for coaxial ultrasonic-assisted laser shot peening, which mainly includes a vibration rod, a horn, a piezoelectric ceramic, a first optical glass, a second optical glass, a vibration rod and a horn A through hole is machined in the axial center, and the lower end of the vibration rod is fixedly connected with the upper end of the horn; the first optical glass is located on the top of the vibration rod, and the second optical glass is located at the bottom of the horn. The upper end of the vibrating rod extends out of the upper surface of the upper casing and is fixedly connected with it, and the piezoelectric ceramic is mounted on the vibrating rod. In the ultrasonic vibration device, after the piezoelectric ceramic is energized, the electrical energy is converted into mechanical energy to generate ultrasonic waves, and the amplitude of the mechanical vibration is amplified through the horn. A through hole is machined in the axial center of the vibrating rod and the horn, which provides a propagation channel for the laser, and realizes the coaxial propagation of the ultrasonic vibration wave and the laser shock wave. To ensure the coupling of the two during the propagation process, to promote the dynamic recrystallization behavior of the material, and to prepare metal parts with ultra-fine grain surfaces.
