The numerical simulation method is applied to analyze the pressure bar system.The effect of the variable section on the pressure bar is studied.With numerical simulation
the response of different rising front of trapezium impulse and triangle impulse is studied.Compared with the non-variable section bar
the amplitude and waveform of stress wave has been altered greatly in the variable section bar.Regardless of the trapezoidal pulse or triangular pulse
stress wave amplitude should be decreased in the variable section bar.The simulation results have certain reference value for analysis on experimental result.
