Fluid mechanics analysis including the computational fluid dynamics analysis (laminar and turbulent flow and thermal fluid) and acoustic analysis. Convection current right unit or the steady-state transient analysis.
ANSYS software as a powerful structural analysis and structural optimization software, with more to the physical field and function, allow in the same model and calculation of woe, such as: hot-stress, magnetic-hot, magnetic-structure, fluid-hot, fluid-structure, hot-electricity, circuit coupling electromagnetic field, the electromagnetic and piezoelectric evil and analysis, etc.
By defining the design variables, the state variables and the objective function, optimization variables, can use ANSYS optimization tools and parameters of model design language APDL size, shape, location, manufacturing costs, support natural frequency and material optimization design. ANSYS program offers two optimization methods: Zero order method and the first-order method. For these two methods, ANSYS program provides a series of analysis-evaluation-fixed cycle.
3 ANSYS in the application of ultrasonic sliprings design
The Ultrasonic fiber optical rotary joint (Ultrasonic Motor) is the use of Piezoelectric Ceramic (Piezoelectric Ceramic) is the converse Piezoelectric effect, namely, in under the action of alternating electric field, Piezoelectric will produce the telescopic phenomenon, through the various vibration modes and the transformation of the expansion to close, will directly into electricity mechanical vibration can, and make use of friction into a rotating (or other movement way) mechanical energy of you move device. Its principle is showed in the figure. The ultrasonic motor is a kind of new automatic control actuator, is to the traditional electromagnetic motors breakthrough and power added, have very big application prospect.
The finite element method is of the ultrasonic motor vibrator undertake frequency, modal analysis of the most commonly used methods. Its advantage is that can adapt to the more complex, including oscillator by force and constraint boundary conditions, the structure damping, and different materials, complex shape structure composed of etc. The emergence of ANSYS software, for of the through bore slip rings is finite element analysis, optimization design, design reliability, motion simulation, modular design, and other aspects of the design provides a means of realization.
