Using the dynamic finite element method, two-dimensional numerical analysis of propagation characteristics of stress waves in a conical stress wave amplifier is performed, and geometric factors, input pulse shape, pulse rising time, etc. affecting the transmission wave amplification factor and waveform are discussed. References for the supply force wave riveter design. The calculated results are compared with the experimentally measured values ​​on the Hopkinson bar and calculated values ​​of the characteristic lines. The agreement with the experimental results is quite satisfactory, compared with the one-dimensional line method. The calculation accuracy has also been greatly improved, especially in the vicinity of the transmission peak pressure.
