In this paper the static stress distribution of closed valve during diastole under the peak across valve pressure difference is analyzed with nonlinear finite element method.
用有限元数值方法计算了在心室舒张期瓣膜关闭瞬时峰值跨瓣压差作用下的静态应力分布。
The peak value varies in different fault conditions and it can be used as a characteristic for diagnosing leakage fault of exhaust valve, the fault in initial stages can also be diagnosed.
可以将三阶谱的峰值作为判断气阀是否漏气的一个诊断特征量,同时也为诊断内燃机气阀的早期漏气故障提供了依据。
Application Cavitation, liquid hammer and pressure peak may occur in hydraulic systems with changes in flow velocity, e. g. fast closing of a valve or pump starts and stops.
应用空化,液体铁锤和压力顶峰可能用在流动速度方面的变化在液压系统里发生,例如一阀门或者泵的快关闭起停。
