摘 要 本次畢業(yè)設計是關于液壓升降舞臺的設計。首先對液壓升降舞臺作了簡單的概述；接著分析了液壓升降舞臺的選型原則及計算方法；然后根據(jù)這些設計準則與計算選型方法按照給定參數(shù)要求進行選型設計；接著對所選擇的液壓升降舞臺各主要零部件進行了校核。最后簡單的說明了液壓升降舞臺的安裝與維護。目前，液壓升降舞臺正朝著長距離，高速度，低摩擦的方向發(fā)展，近年來出現(xiàn)的液壓升降舞臺就是其中的一個。在液壓升降舞臺的設計、制造以及應用方面,目前我國與國外先進水平相比仍有較大差距,國內在設計制造液壓升降舞臺過程中存在著很多不足。 Abstract The design is a graduation project about the hydraulic pressure lift proscenium. At first, it is introduction about hydraulic pressure lift proscenium. Next, it is the principles about choose component parts of hydraulic pressure lift proscenium. After that t hydraulic pressure lift proscenium abase on the principle is designed. Then, it is checking computations about main component parts of hydraulic pressure lift proscenium. At last, it is explanation about fix and safeguard of hydraulic pressure lift proscenium. Today, long distance, high speed, low friction is the direction of hydraulic pressure lift proscenium’s development. Hydraulic pressure lift proscenium is one of them. At present, we still fall far short of abroad advanced technology in design, manufacture and using. There are a lot of wastes in the design of hydraulic pressure lift proscenium。
