半径比率
Examples
- The effect of the radius ratios of the hollow cylinder to the wave propagation is also discussed
还讨论了压电圆柱壳体半径比对波传播的影响。 - Simulation results show that better atomization can be realized by enhancing the cavitation intensity via increasing the injection pressure difference or decreasing the nozzle inlet round angle - radius ratio
通过模拟计算可知，提高喷射压差和减小喷孔入口圆角半径都可以提高空穴强度，同时也发现提高喷孔长径比可以使空穴在喷孔出口截面上分布更为均匀。 - Based on this model , the effects of geometric and structural parameters , such as injection pressure , rear pressure , length - diameter ratio , inlet round angle - radius ratio and non - axis symmetry of nozzle , on the distribution of the cavitation inside the nozzle are analyzed
基于这一模型进一步分析了喷射压力、背压和喷孔长径比、喷孔入口圆角比、非轴对称喷孔等几何结构参数对喷孔内空穴分布的影响。 - The threshold speed and the typical characteristics of the oil whip of the system are simulated under the nonlinear model of oil film force , and the state of motion and type of the bifurcation are analyzed by floquet multiplicators which is computed by the shooting method . secondly , the the nonlinear dynamical model of the low - pressure rotor - bearing system by column bearing with reduced dimensions is presented . the numerical results show the rule of the amplitude with the eccentricity of rotor , the length - to - diameter ratio , oil viscosity and the clearance - to - radius ratio of the bearing under the definite speed
