基于NSGA-Ⅱ算法的超声骨刀换能器设计与模态优化
Design and modal optimization of ultrasonic osteotome transducer based on NSGA-Ⅱ algorithm
摘要
Abstract
To achieve multi-modal separation and parasitic modal suppression near the working frequency of the ultrasonic osteotome transducer,and improve the efficiency of ultrasonic energy transmission,a new method for the design and modal optimization of the ultrasonic osteotome transducer is established by integrating modular design,elec-tromechanical equivalent four-terminal network,modal frequency sensitivity analysis,and NSGA-Ⅱ(non-dominated sorting genetic algorithm).The experimental results demonstrate the effectiveness of the established multi-objective optimization model for steady-state amplitude and modal frequency difference.Utilizing the NS-GA-Ⅱ algorithm,the global optimal solution for structural parameters is successfully obtained.The prototype exhibits a working frequency of 27.56 kHz,with a steady output amplitude of 110 μm.Notably,the amplitude amplification factor is increased by 50.43％compared to pre-optimization levels.Furthermore,within a±2 kHz range around the working frequency,no parasitic modals are observed,effectively mitigating mode density issues and showing a significant optimization effect.关键词
