【摘要】：液壓多路換向閥簡稱液壓多路閥,是為了滿足多執(zhí)行機(jī)構(gòu)的要求而設(shè)計開發(fā)的。其結(jié)構(gòu)是以多個換向閥為主體,集成了各種功能閥,如安全閥、單向閥、壓力補(bǔ)償閥、節(jié)流閥等。通過換向閥的換向,實現(xiàn)了對多個執(zhí)行機(jī)構(gòu)控制的多功能集成閥。結(jié)構(gòu)復(fù)雜,功能強(qiáng)大,因此對多路閥的設(shè)計和維修難度都很大。為了解決這種問題,多路閥試驗臺應(yīng)運而生。它通過模擬多路閥工作狀態(tài),得到相應(yīng)的壓力、流量數(shù)據(jù)曲線,通過比較分析,能極大的幫助多路閥的維修和設(shè)計。由于我國的液壓技術(shù)發(fā)展時間短,國內(nèi)的液壓多路閥試驗臺大多存在著功能不全、可靠性差、測試精度和試驗效率低等問題,對多路閥特殊功能的測試和研究更是比較少。而且主要以手控液壓多路閥為研究對象,結(jié)構(gòu)簡單、聯(lián)數(shù)少,對結(jié)構(gòu)復(fù)雜的液控和電液比例控制液壓多路閥的還研究較少。因此,以復(fù)雜程度高的多路閥為研究對象,對其進(jìn)行液壓多路閥試驗臺的設(shè)計和研究具有重要意義。本文以典型的液控式、半整體式川崎多路閥為試驗對象,結(jié)合多路閥測試的最新試驗標(biāo)準(zhǔn),完成了多路閥試驗臺系統(tǒng)設(shè)計并對多路閥功能進(jìn)行測試研究。該試驗臺主要設(shè)計包括以下三個部分:液壓系統(tǒng)原理、試驗臺結(jié)構(gòu)和測控系統(tǒng)設(shè)計。通過對試驗項目的需求分析和多路閥特性功能分析,分析并設(shè)計液壓系統(tǒng)原理圖�？紤]試驗臺的功能要求、成本高低、安全穩(wěn)定、使用方便等因素,解決多路閥試驗臺的整機(jī)結(jié)構(gòu)設(shè)計。同時根據(jù)多路閥加載模塊原理圖,利用SolidWorks軟件分析并設(shè)計了集成塊。以及根據(jù)多路閥測控系統(tǒng)的特點,編制試驗流程,基于MCGS軟件設(shè)計人機(jī)界面,分析測控系統(tǒng)的設(shè)計理念。根據(jù)測試結(jié)果分析多路閥結(jié)構(gòu)、性能的合理性,同時還研究了多路閥主流的特性機(jī)能的測試方法,利用AMESim軟件平臺開發(fā)出多路閥動臂聯(lián)模塊的HCD仿真模型,并基于HCD仿真模型對多路閥典型的工作狀態(tài)進(jìn)行的動態(tài)特性研究。論文將液壓、機(jī)械、電氣、控制理論和軟件開發(fā)等多學(xué)科技術(shù)有機(jī)結(jié)合,完成了多路閥試驗臺的開發(fā)與研究,并交與客戶使用。本文研究所得相關(guān)結(jié)論,不僅對多路閥試驗臺研制提供詳細(xì)實例和參考思路,同時對多路閥的研制也提供了一定理論指導(dǎo)。
[Abstract]:Hydraulic multiplex valve is designed and developed to meet the requirements of multiple actuators. Its structure is composed of multiple directional valves and various functional valves, such as safety valve, one-way valve, pressure compensation valve, etc. Throttle valve, etc. By reversing the direction valve, the multi-function integrated valve controlled by multiple actuators is realized. The structure is complex and the function is powerful, so it is very difficult to design and maintain the multi-way valve. The multiway valve test rig emerges as the times require. By simulating the working state of the multiway valve, the corresponding pressure and flow data curves can be obtained. Through comparison and analysis, it can greatly help the maintenance and design of the multiway valve. Because of the short development time of hydraulic technology in our country, Most of the domestic hydraulic multi-way valve test stands have some problems, such as incomplete function, poor reliability, low test precision and low test efficiency, etc. The test and research on the special function of multi-way valve is less, and the main research object is manual hydraulic multi-way valve, the structure is simple, the connection number is less, and the hydraulic multiplex valve with complex structure and electro-hydraulic proportional control is less. It is of great significance to design and study the hydraulic multiway valve test rig with high complexity. In this paper, the typical hydro-controlled and semi-integrated Kawasaki multiway valve is used as the test object. Combined with the latest test standard of multi-way valve test, the system design of multi-way valve test bench is completed and the function of multi-way valve is tested and studied. The main design of the test bench includes the following three parts: the principle of hydraulic system, Design of test bed structure and measurement and control system. By analyzing the requirements of the test project and the function analysis of multi-channel valve characteristics, the schematic diagram of hydraulic system is analyzed and designed. Considering the functional requirements of the test bed, the cost is high and low, and the safety and stability are considered. The structural design of the multiway valve test-bed is solved by using convenience and other factors. At the same time, according to the schematic diagram of the multi-way valve loading module, the integrated block is analyzed and designed by using SolidWorks software, and the test flow is compiled according to the characteristics of the multi-way valve measurement and control system. The man-machine interface is designed based on MCGS software, and the design concept of the measurement and control system is analyzed. According to the test results, the structure and the rationality of the performance of the multi-way valve are analyzed. At the same time, the testing method of the main characteristic function of the multi-way valve is also studied. Based on the AMESim software platform, the HCD simulation model of the multi-way valve arm is developed, and the dynamic characteristics of the typical working state of the multi-way valve are studied based on the HCD simulation model. The control theory and software development are combined organically, and the development and research of the multi-way valve test-bed are completed, and the research results are given to the customer. It not only provides a detailed example and reference idea for the development of the multi-way valve test rig, but also provides some theoretical guidance for the development of the multi-way valve.
