剪式液压升降台相关参数的确定

设计剪式液压升降台要解决的关键问题,是科学、合理地确定液压缸的有效行程及其它结构参数.液压缸的有效行程受各结构参数的影响,而这些参数又影响液压缸的受力,各参数之间的关系错综复杂.要设计出液压缸受力小,而又能满足运动要求的剪式液压升降台,必须明确各参数之间的相互关系,进行综合分析.通过分析剪式液压升降台的运动过程,推导出了满足升降台升降的相关参数的关系式;通过分析和比较升降台在负重上升过程中液压缸推力的变化规律,确定了铰架仰角a的取值范围、液压缸的有效行程及有关结构参数的取值规律,为升降台的系列设计提供了理论依据.

Determination of Relevant Parameters for Scissor Type Hydraulic Aerial Platforms

The key problem need to be solved in the design of a scissor type hydraulic aerial platform is to scientifically and rationally determine effective the stroke of hydraulic cylinder and other structural parameters. The effective stroke of hydraulic cylinder is influenced by structural parameters and these parameters will also influence the loading on hydraulic cylinder. Relationship between the parameters is intricate and complex. In order to design a scissor type hydraulic aerial platform not only with low ...
