Abstract
En 中文
A novel dual-axis piezoelectric system designed for elliptical vibration cutting (EVC) is reported. The system features a topology-optimized compliant mechanism for transmitting the motion of parallel-arranged stacked piezoelectric actuators (SPAs). Static and dynamic analyses of the mechanism were conducted using the solid isotropic material with penalization (SIMP) approach with hexagonal-element. A comprehensive optimization model was developed to guide the topological evolution, incorporating constraints related to resonance frequencies, motion coupling, fatigue durability, and manufacturability. The performance of the designed compliant mechanism was validated via finite element simulations. The fabricated prototype achieved strokes of <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$\mathbf{13.04}$</tex-math></inline-formula> and <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$\mathbf{12.55}\,\boldsymbol{\mu}\mathbf{m}$</tex-math></inline-formula> in two directions, respectively, with corresponding resonance frequencies of 4357 and 3178 Hz. A decoupled control strategy combining a proportional and integral (PI) controller and model-based feedforward compensation was implemented, yielding minimal inter-axis crosstalk. Trajectory tracking experiments demonstrated the effectiveness of the designed closed-loop system.
