摘　　要：波形平面度是平面波发生器的关键参数.通过分析平面波发生器的工作原理,设计了结构简单的平面波发生器,并应用有限元软件LS-DYNA对平面波形的平面度进行了数值模拟.结果表明:在直径60%的范围内,在轴心和边缘的时间平面度小于0.05μs.说明设计的平面波发生器能够满足实验要求,设计方法可行.Flatness of plane wave is a key parameter of plane wave generator. A reliable plane wave generator is designed on analyzing work principle of plane wave generator. Numerical simulation of output waveform flatness is carried out by the finite element software LS-DYNA. Simulation results L indicate that flatness of waveform is less than 0.05μs within the range of 60% of the diameter. Results show that the plane wave generator satisfy the requirement of experimentation and the design method is reasonable.
