Regarding the passage as a linear elastic system and using the frequency

本文视通道为一线性弹性系统,使用频率响应法,给出了对其自振频率及示功图上出现的腔振,相移和图形失真误差的理论和实验分析。要得到不失真的示功图,应使整个测量系统的频率特性在50倍被测压力基频范围内平坦。因此,应尽量提高测压通道的自振频率,这可以用加大通道直径、缩短通道长度来达到。通道的自振频率可由(8)式计算。燃烧发火时,在测压通道入口处发生压力对时间一次导数的跳跃,从而激起腔振(式(29))。腔振可通过增加通道阻尼或加接滤波网络来消除。后一法更为有效,因为此时仍可使用高自振频率的通道。示功图的相移可用热力修正法修正。
