摘　　要：研究并实现了基于材料特征的超声仿真系统,并在图形测量及处理方面都取得了满意的成果。为进一步证明所提出的数值模拟模型的适用性,在同一时域下将数值模拟模型获得的信号与实际测量数据进行了对比。实验结果显示,材料的声波传播可以进行数值模拟仿真。此外,建立的数值模拟模型可获得比实际测量数据更多的超声数据及规律,并能够在实际材料模型建立前预测模型的超声特征。上述超声仿真数值模拟技术及模型的应用不仅可以节省大量的时间和资金,也能够使设计人员更好地理解设计中存在的不足,从而能够更有效和合理地修改设计模型。A system for simulation researches of measurement and processing is presented,and has been obtained good satisfactory.The received signal from the simulation is compared to that of an actual measurement in the time domain in order to verify the effect.The comparison of simulated and experimental data clearly shows that acoustic wave propagation can be modeled.The feasibility has been demonstrated in an ultrasound transducer setup for material property investigations.The simulation model provides a way to predict the received signal before anything is built.Such a virtual design and testing procedure not only can save us time and money,but also can provide better understanding on design failures and allow us to modify designs more efficiently and economically.
