Abstract:
Using the workbench the liquid jet impact the reed vibration problems that with three different reed wedge shapes are analysed. The influence of reed vibration characteristics in different pressure and reed wedge shapes are also investigated. Results indicate that the time needed for reed to reach steadystate is inversely proportional to the jet pressure, the size of amplitude is proportional to the jet pressure, the frequency of reed vibration is proportional to the jet pressure or not change. Under the same jet pressure, sequence of the time interval in which the jet get steadystate is triangle, square and semicircle and the interval of triangle wedge is the longest. The sequence of amplitude is square, triangle and semicircle and the amplitude of square is the largest. The sequence of frequency is triangle, semicircle and square and the triangle frequency is the highest.
