【摘要】 应用多芯片组件(MCM)技术,对超声波电机驱动单元的集成技术进行了初步探索;建立了MCM的三维有限元的热分析模型,并在空气自然对流情况下,对温度分布和散热状况进行了模拟计算;定量分析了空气强迫对流MCM模型温度分布和散热状况的影响。模拟分析结果为基于MCM的超声波电机驱动单元的设计提供了重要的理论依据,对于提高同类产品本身的整体性能和国际竞争力具有重要的理论意义和实用价值。更多还原

【Abstract】 Based on the multi-chip module(MCM)technique,one integrated circuit unit driving for ring-type traveling-wave ultrasonic motor(RTWUSM)is designed in this paper.The 3-dimensional thermal analysis model used by finite element method(FEM)is also been built in this paper.The temperature distribution and radiating condition are calculated under air free convection,and then the quantitative analysis is made for the IC driving for RTUSM based on MCM technique under air forced convection.The results are the foundations for the IC driving of other motors.更多还原
