【摘要】 空化常见于液压系统中,不仅影响传动效率,而且会对液压元器件产生破坏等不利影响。对圆形管道中的空化展开研究,发现管道中空化气泡溃灭后,压力波的反射与汇聚会引起二次空化现象,二次空化与一次空化相互作用,其发生有显著的相关性,此研究为液压系统中的空化预防与控制提供了新的思路。更多还原

【Abstract】 Cavitation is a common phenomenon in hydraulic systems. Cavitation not only affects the transmission efficiency, but also damages the hydraulic components etc. Researching on the cavitation in a circular pipe, we found the secondary cavitation caused reflection and convergence of pressure wave. The interactions between secondary and first cavitation are significantly correlated. The findings of characteristics can provide a new method for cavitation prevention and control in hydraulic systems design.更多还原
