Abstract
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 indicate that flatness of waveform is less than 0.05 μs 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.
