【摘要】：電液伺服閥作為電液伺服系統(tǒng)的關(guān)鍵元件，廣泛應(yīng)用于航空航天很多要求快速精確反應(yīng)并且功率大的控制場(chǎng)合。伺服閥中精密部件加工和裝配對(duì)于伺服閥的性能指標(biāo)影響很大，其中功率級(jí)滑閥的加工是伺服閥生產(chǎn)的關(guān)鍵因素。目前滑閥加工較為先進(jìn)的配磨方法為液動(dòng)配磨的方法，加工方式為偶件配做，各閥芯閥套并沒(méi)有互換性，配磨后的滑閥要經(jīng)過(guò)整閥調(diào)試才能確定合格與否以及加工質(zhì)量的好壞。為了提高伺服閥的制造效率，需要在滑閥配磨結(jié)束之后對(duì)于加工質(zhì)量以及裝配成整閥后的性能進(jìn)行評(píng)價(jià)。 本文首先明確了伺服閥液動(dòng)配磨的工作原理，并且得到了配磨曲線的基本特性，分析了伺服閥的主要性能指標(biāo)。利用灰關(guān)聯(lián)分析方法，得到了影響各性能指標(biāo)的主要加工誤差因素。根據(jù)雙噴嘴擋板式伺服閥的結(jié)構(gòu)特點(diǎn)，利用高級(jí)系統(tǒng)工程建模仿真平臺(tái)AMESim對(duì)各個(gè)組件分別建模并根據(jù)相互關(guān)系建立整閥模型。其中功率級(jí)滑閥的各個(gè)加工參數(shù)可以在參數(shù)模式下進(jìn)行獨(dú)立設(shè)置進(jìn)行仿真，得到伺服閥的流量壓力以及內(nèi)泄漏特性曲線。根據(jù)國(guó)家軍用標(biāo)準(zhǔn)及伺服閥試驗(yàn)標(biāo)準(zhǔn)規(guī)定的伺服閥相應(yīng)特性指標(biāo)的合格標(biāo)準(zhǔn)確定滑閥各加工參數(shù)的合格范圍。 基于液動(dòng)配磨臺(tái)的測(cè)量原理，利用AMESim建立的流量式測(cè)量的仿真模型對(duì)液動(dòng)配磨臺(tái)的測(cè)量過(guò)程進(jìn)行仿真。分別將被測(cè)滑閥加工參數(shù)設(shè)置為滿足整閥性能要求的參數(shù)范圍，得到不同的搭接量測(cè)量曲線。定義一系列描述曲線特征的參量，找到各參量與滑閥參數(shù)的關(guān)系，從而得到曲線特征參量與整閥特性之間的關(guān)系。最后利用實(shí)際滑閥進(jìn)行配磨實(shí)驗(yàn)，得到搭接量測(cè)量曲線，記錄下曲線的特征參數(shù)。對(duì)各組滑閥進(jìn)行跟蹤，進(jìn)行整閥調(diào)試實(shí)驗(yàn)，得到對(duì)應(yīng)的整閥特性。對(duì)于本文中軟件仿真的滑閥評(píng)價(jià)標(biāo)準(zhǔn)進(jìn)行驗(yàn)證，并對(duì)于實(shí)驗(yàn)呈現(xiàn)的結(jié)果加以分析。實(shí)驗(yàn)證明，仿真得到的評(píng)價(jià)標(biāo)準(zhǔn)是可靠的，可以將其應(yīng)用于伺服閥閥芯閥套評(píng)價(jià)系統(tǒng)上加以應(yīng)用，，評(píng)估結(jié)果能夠滿足生產(chǎn)的需要。
[Abstract]:As the key component of electro-hydraulic servo system, electro-hydraulic servo valve is widely used in many control situations which require rapid and accurate response and high power. The machining and assembling of precise parts in servo valve have great influence on the performance index of servo valve, and the machining of power level slide valve is the key factor in the production of servo valve. At present, the more advanced grinding method of slide valve is the method of hydrodynamic grinding, the processing method is the matching of couple parts, the valve sleeve of valve core does not have interchangeability, the slide valve after grinding must go through the adjustment of the whole valve to determine whether it is qualified or not and the quality of processing. In order to improve the manufacturing efficiency of the servo valve, it is necessary to evaluate the machining quality and the performance of the whole valve after the sliding valve grinding is finished. In this paper, the working principle of servo valve hydrodynamic grinding is clarified, and the basic characteristics of grinding curve are obtained, and the main performance indexes of servo valve are analyzed. The main processing error factors affecting each performance index are obtained by using grey correlation analysis method. According to the structural characteristics of the double nozzle baffle servo valve, each component is modeled by the advanced system engineering modeling and simulation platform AMESim and the whole valve model is established according to the mutual relationship. The machining parameters of the power level slide valve can be set up independently in the parameter mode and the flow pressure and internal leakage characteristic curve of the servo valve can be obtained. According to the national military standard and servo valve test standard, the qualified standard of servo valve characteristic index is used to determine the qualified range of each processing parameter of slide valve. Based on the measuring principle of the hydraulic distribution mill, the measurement process of the hydraulic distribution mill is simulated by using the flow measurement simulation model established by AMESim. The machining parameters of the tested slider valve were set to the range of parameters to meet the performance requirements of the whole valve, and different lap measurement curves were obtained. A series of parameters describing the characteristics of the curve are defined, and the relationship between the parameters and the parameters of the slide valve is found, and the relationship between the characteristic parameters of the curve and the characteristics of the whole valve is obtained. Finally, using the actual sliding valve to carry out the grinding experiment, the lap measurement curve is obtained, and the characteristic parameters of the curve are recorded. The whole valve was tracked and the whole valve characteristic was obtained. The evaluation standard of slide valve in software simulation in this paper is verified, and the experimental results are analyzed. The experimental results show that the evaluation standard obtained by simulation is reliable and can be applied to the evaluation system of valve core and valve sleeve of servo valve. The evaluation results can meet the needs of production.
