摘 要
液壓缸是液壓系統(tǒng)中最廣泛應(yīng)用的一種液壓執(zhí)行元件。液壓缸是將液壓泵輸出的壓力能轉(zhuǎn)換為機(jī)械能的執(zhí)行元件,它主要是用來輸出直線運動。
液壓傳動和液力傳動均是以液體作為工作介質(zhì)來進(jìn)行能量傳遞的傳動方式。液壓傳動主要是利用液體的壓力能來傳遞能量;而液力傳動則主要是利用液體的動能來傳遞能量。由于液壓傳動有許多突出的優(yōu)點,因此,它被廣泛地應(yīng)用于機(jī)械制造、工程建筑、石油化工、交通運輸、軍事器械、礦山冶金、輕工、農(nóng)機(jī)、漁業(yè)、林業(yè)等各方面。同時,也被應(yīng)用到航天航空、海洋開發(fā)、核能工程和地震預(yù)測等各個工程技術(shù)領(lǐng)域。

Abstract
Hydraulic cylinders are one of the hydraulic action components, which are widely used to transfer hydraulic power produced by pump to mechanical power with the manner of straight movement.
Hydraulic transmission hydraulic transmission and are based on the liquid as energy transfer medium to the drive. Mainly the use of hydraulic fluid to transmit pressure to energy; and hydraulic transmission is mainly used to transfer the kinetic energy of liquid energy. As a result of hydraulic many prominent advantages, therefore, it is widely used in machine building, construction, petrochemical, transportation, military equipment, mine metallurgy, light industry, agricultural, fisheries, forestry and so on. At the same time, also be applied to aerospace, marine development, nuclear engineering and earthquake prediction in various fields of engineering and technology.
In this paper, the parameters of the hydraulic cylinder design of the system to conduct in-depth research, the establishment of hydraulic cylinder CAD prototype software system, the main research results are as follows: 1. The working principle of hydraulic cylinder systems analysis on the basis of summed up the work of the form of hydraulic cylinder and the major form of installation. Analysis of hydraulic cylinders in the structural characteristics of the main components on the basis of the assembly based on object-oriented model of product design of hydraulic cylinder; 2. Research-oriented products feature modeling, product modeling based on object-oriented methods and technology, based on the characteristics of the hydraulic cylinder product model. Studied for parametric design of hydraulic cylinder of standard parts library and database modeling modeling techniques, and accordingly established a database of hydraulic cylinder model parameters and the hydraulic cylinder assembly based on the model parameters; 3. To establish fluid pressure cylinder of CAD system model parameters, based on the commercial CAD software, has developed a hydraulic cylinder Parametric CAD software prototype system.
