【摘要】 液压系统大量采用液压元件和管路。结构较为复杂,故障发生率较高,其中液压系统冲击是常见故障之一。液压冲击的实质主要是管道中的流体因突然停止运动而导致动能向压力能的瞬间转变。本文建立了流体突然停止运动和运动部件突然制动时产生液压冲击的数学计算模型:并针对产生液压冲击的元件和回路提出了控制措施。更多还原

【Abstract】 A great deal of hydraulic components and pipelines are adopted in hydraulic system. Structure of the hydraulic system is more complicated and the occurrence rate of malfunctions is higher. Impact is one of the familiar malfunctions in hydraulic system. The substance of the hydraulic impact is that the kinetic energy changes to pressure energy of moment when the liquid in the piping stopping short the sport. This text establishes the mathematics calculation model for the hydraulic impact when the liquid stopping short the sport and the athletic component applying the brake suddenly. Aimed at the components and loops which produce the hydraulic impact,control measures are also putted forward.更多还原
