液压传动系统设计与计算(中文4300字,英文3600字)
1. 明确设计要求进行工况分析
   在设计液压系统时，首先应明确以下问题，并将其作为设计依据。
    主机的用途、工艺过程、总体布局以及对液压传动装置的位置和空间尺寸的要求；
主机对液压系统的性能要求，如自动化程度、调速范围、运动平稳性、换向定位精度以及对系统的效率、温升等的要求；液压系统的工作环境，如温度、湿度、振动冲击以及是否有腐蚀性和易燃物质存在等情况。
在上述工作的基础上，应对主机进行工况分析，工况分析包括运动分析和动力分析，对复杂的系统还需编制负载和动作循环图，由此了解液压缸或液压马达的负载和速度随时间变化的规律，以下对工况分析的内容作具体介绍。

Hydraulic actuation system design and computation
1. clearing about the design request to carry on the operating mode analysis.
   When design hydraulic system below, first should be clear about the question, and takes it as the design basis.
   Main engine use, technological process, overall layout as well as to hydraulic gear position and spatial size request; The main engine to the hydraulic system performance requirement, like the automaticity, the velocity modulation scope, the movement stability, the commutation pointing accuracy as well as the request which to the system efficiency, warm promotes; Hydraulic system working conditions, like temperature, humidity, vibration impact as well as whether has situation and so on corrosiveness and heat-sensitive material existence.
In in the above work foundation, should carry on the operating mode analysis to the main engine, the operating mode analysis including the movement analysis and the mechanical analysis, also must establish the load and the operating cycle chart to the complex system, from this understood the hydraulic cylinder or the oil motor load and the speed change as necessary the rule, below makes the concrete introduction to the operating mode analysis content
