摘  要

    油缸是最常见的液压元件，可靠性是指系统不因意外的原因而无法工作(如油管破裂、无电等情况)。可维护性是指系统尽可能简单，元件尽可能选标准件，结构上尽可能使维护方便．安全性是指不因液压缸的故障导致后车厢盖的其它事故．效率是指液压缸的各种能量损失尽可能的小。上述要求中，除满足系统的动力要求外，最重要的是保证系统的安全性和可靠性。

Abstract

The hydraulic system to transfer power, ensure adequate power is its basic requirement. In addition, consider the system stability, reliability, maintainability, safety and efficiency. The stabilizing means when the system works steady motion and system performance stability (such as environmental temperature on the influence of oil etc). Reliability refers to the system is not due to accident reason to work ( such as tubing rupture without electricity, etc. ). Maintainability is referred to the system as simple as possible, element is chosen as far as possible standard parts, structure as much as possible so that the maintenance is convenient. Security is not due to the fault of the hydraulic system causes the antenna frame collapse or other accidents (such as the drop out of control, antenna due to gravity acceleration whereabouts ) . Efficiency refers to the hydraulic system of the various energy loss as small as possible. The above requirements, in addition to meet the power requirements, the most important thing is to ensure the safety and reliability of the system.
Keywords: hydraulic system,
