摘要： The present disclosure provides a device and a method for reducing and homogenizing residual stress during machining in which a workpiece is fixed, such as milling, boring, drilling and planning, with which high-energy acoustic waves are emitted to the workpiece via a tight contact between a plurality of high-energy wave exciters on a bench and a workpiece coated with a coupling medium, and residual stress inside the machined workpiece is reduced and homogenized through elastic wave energy generated in the workpiece by the high-energy acoustic waves. In this way, the purpose of reducing and homogenizing the residual stress while machining is achieved, realizing a stress-free machining, and the deformation of the workpiece during and after machining is minimized.

摘要： A device and a method for switchable vibration modal ultrasonic are provided. The device includes a hollow shaft, an ultrasonic motor, a limit shell, an electromagnet, a moving tool head, a vibration source and a tool head. The structure design of the ultrasonic motor, the magnetostrictive materials and the drive coil combination of different functions are configured so that, without changing the condition of components, the ultrasonic can switch mode, namely the longitudinal vibration, torsional vibration, and longitudinal and torsional vibration in three different vibration modes. During the operation of the device, different vibration modes are excited without changing the parts, which meets the machining requirements of different vibration forms. Meanwhile, the operation is more convenient and faster, and the overall design structure of the device ensures the efficient and safe operation of the device.

摘要： A haptic actuator includes mechanical links defining a first J-trajectory and mechanical links defining a second J-trajectory as well as a motor coupled to the mechanical links so as to synchronously accelerate a first mass over the first J-trajectory and a second mass over the second J-trajectory. During a first time interval, reactive forces of the first mass accelerating substantially balance reactive forces of the second mass accelerating and during a second time interval reactive forces of the first mass accelerating do not substantially balance reactive forces of the second mass accelerating. This un-balanced condition results in a tap signal being produced.

摘要： A variable-frequency surface acoustic wave electronic cigarette includes an atomizer. An atomization cavity is disposed in the atomizer, and a variable-frequency surface acoustic wave atomization chip is disposed at a lower portion of the atomization cavity. An inverted trapezoidal interdigital transducer is disposed on the variable-frequency surface acoustic wave atomization chip. An e-liquid storage cavity is disposed in the atomization cavity. A porous ceramic sheet is disposed between the e-liquid storage cavity and the atomization chip. The new variable-frequency surface acoustic wave electronic cigarette can realize any adjustment of the working frequency within a set range, thereby realizing the autonomous regulation and control of a smoke particle size after atomization of the e-liquid.
