pressure and velocity stages
解釋
壓力速度聯合分級法-
The method is described as follows : the velocity of the moving part and the gas chamber pressure were measured with a dynamic test measurement system ; a dynamic model was built on force analysis of the moving part ; the total kinetic resistance replaced the horizontal friction and water resistance ; then the resistance - velocity relation curves at moving stages were obtained ; with the empirical formula of the gas chamber pressure and the resistance - velocity relation curves, the preliminary dynamic characteristics were analyzed and the structural form and key parameters of an underwater assault rifle were determined
具體方法為:由動力學測量系統測得活動件速度和氣室壓力;分析活動件的受力,建立動力學模型;以運動總阻力代替水平方向上的摩擦阻力和水阻力,獲得各運動階段的阻力速度關系曲線;利用氣室壓力經驗公式和阻力速度關系曲線,對水下突擊步槍進行初步的動力學分析,確定其構造型式及主要參數。 -
The method permits the calculation of the three stages of shock wave evolution, and gives the temporal and spatial relationship of peak pressure, velocity, and profile of shock wave
