摘要: Industries including semiconductor, biotechnology, and nanotechnology are seeking compact reliable nanometer resolution positioning techniques. To address this demand, article presents a friction-drive rotary stage driven by piezoelectric transducer (PZT) actuator. This includes multilayer PZT actuator, the Scott-Russell mechanism, an actuation stage, preload spring, output shaft. Its is accomplished stick-slip effect between wire electrodischarge-machining Finite element analysis Taguchi optimization method were extensively conducted to analyze displacement, stress, vibration behavior for optimum design. As shown experimental results, achieved of 0.13μrad speed 0.15°∕h tuning spring.
