內(nèi) 容 提 要
液壓泵是液壓系統(tǒng)的動(dòng)力元件，其性能的好壞直接影響到液壓系統(tǒng)的工作性能和可靠性，在液壓傳動(dòng)中占有極其重要的地位。
設(shè)計(jì)主要有兩個(gè)部分的內(nèi)容：液壓軸向柱塞泵的噪聲分析和結(jié)構(gòu)的改進(jìn)。其中論文主要集中在液壓軸向柱塞泵的噪聲分析及實(shí)踐中對(duì)改進(jìn)后與改進(jìn)前的對(duì)比實(shí)驗(yàn)。首先從液壓泵的基本原理著手，結(jié)合軸向柱塞泵自身的特點(diǎn)進(jìn)行介紹。然后分析對(duì)于軸向柱塞泵噪聲的影響因素以及改進(jìn)的方法，優(yōu)化結(jié)構(gòu)又與哪些因素有關(guān)聯(lián)，逐步地說(shuō)明改進(jìn)設(shè)計(jì)的由來(lái)及設(shè)計(jì)步驟。
本次設(shè)計(jì)對(duì)軸向柱塞泵降低噪聲的改進(jìn)，主要是從影響其噪聲的三個(gè)摩擦副（缸體與配流盤(pán)的摩擦、變量頭與滑靴的摩擦、柱塞與柱塞孔的摩擦）進(jìn)行分析，并對(duì)其主要摩擦——缸體與配流盤(pán)的摩擦進(jìn)行了結(jié)構(gòu)改進(jìn)及采用了柱塞包滑靴的結(jié)構(gòu)。經(jīng)過(guò)實(shí)驗(yàn)發(fā)現(xiàn)，配流盤(pán)上的鼠尾的長(zhǎng)度直接影響泵的噪聲，于是作者對(duì)配流盤(pán)上的鼠尾長(zhǎng)度經(jīng)過(guò)一系列的實(shí)驗(yàn)，最后找到了比較合適的尺寸。在這系列的實(shí)驗(yàn)中，選取了幾組缸體與配流盤(pán)進(jìn)行對(duì)比實(shí)驗(yàn)，取得了滿(mǎn)意的效果。
本次設(shè)計(jì)的主要優(yōu)點(diǎn)，就是一切從生產(chǎn)實(shí)踐和試驗(yàn)出發(fā)，具有良好的應(yīng)用前景和較好的經(jīng)濟(jì)價(jià)值。

Summary
Hydraulic pump is the power component of hydraulic  systems, its performance has a direct impact on the performance and reliability of the hydraulic system, it plays a important part in the hydraulic transmission.
The content of paper includes two parts: the noise analysis of hydraulic axial piston pump and improved design of structure. This paper focused on the noise analysis of hydraulic axial piston pump and the contrast experiment before and after the improved design. First based on the basic principles of hydraulic pumps, the axial piston pump is introduced combining with their own characteristics. Then, the impact factors for axial piston pump noise is analyzed, as well as improved methods and what factors are related to optimized structure. Finally, the reason of improved design and the design steps is showed gradually.
The improved design to reduce the noise of the axial piston pump mainly analyze on the three pairs of friction which influenced on the noise of the axial piston pump, such as: the friction between cylinder and plate, the friction between variable and slipper, the friction between plunger and the plunger hole. The paper improves the structure of the first friction and use the structure of slipper with the plunger packaged. The experiment was been proved that the length of the rat tail belong to plate which influence the pump noise. Through a series of experiment on the length of rat tail to found a proper dimension. During the experiment, satisfactory results were achieved because of several groups cylinder and plates were selected in experiment.
Main advantage of this text,all with trial-produce experiment set out,have good application prospect and better economic worth from production practices.
