【摘要】：液壓系統(tǒng)振動是普遍存在的現(xiàn)象。振動不僅影響相關(guān)設(shè)備的正常運(yùn)行,還會產(chǎn)生噪聲污染。本課題的研究對象是實(shí)驗(yàn)室內(nèi)使用的FESTO教學(xué)液壓系統(tǒng)。這個系統(tǒng)的液壓泵站直接安裝在實(shí)驗(yàn)室水磨石地面上,工作時會產(chǎn)生較大的振動和噪聲,嚴(yán)重影響其他實(shí)驗(yàn)室和辦公室的工作,因此很有必要對它的振動特性進(jìn)行研究,并在此基礎(chǔ)上采取合適的隔振減振措施。相關(guān)研究表明,液壓系統(tǒng)的振動主要包括機(jī)械結(jié)構(gòu)的振動和液體介質(zhì)工作產(chǎn)生的振動兩個方面。根據(jù)實(shí)驗(yàn)室液壓系統(tǒng)的振動情況,確定了FESTO液壓系統(tǒng)的振動以機(jī)械結(jié)構(gòu)振動為主,而液體介質(zhì)產(chǎn)生的振動相對較弱。 研究表明,FESTO液壓系統(tǒng)的主要振動形式是受到簡諧力激勵而產(chǎn)生的線性受迫振動,論文建立了液壓系統(tǒng)的單自由度簡諧受迫振動力學(xué)模型,運(yùn)用LabVIEW8.5軟件設(shè)計(jì)了振動測試程序,選用相應(yīng)的測試設(shè)備,對系統(tǒng)進(jìn)行了振動特性測試,并做了頻譜等分析。在測試結(jié)果的基礎(chǔ)上設(shè)計(jì)了橡膠隔振器,用于液壓系統(tǒng)的隔振減振處理,同時對橡膠隔振器性能參數(shù)進(jìn)行了分析計(jì)算。 通過對比液壓系統(tǒng)隔振前后的振動情況和噪聲水平,證明橡膠隔振器具有一定的隔振效果,振動和噪聲有較大幅度的降低,對相鄰實(shí)驗(yàn)室和辦公室已經(jīng)沒有太大影響。
[Abstract]:The vibration of hydraulic system is a common phenomenon. Vibration not only affects the normal operation of related equipment. The research object of this subject is the FESTO teaching hydraulic system which is used in the laboratory. The hydraulic pump station of this system is installed directly on the terrazzo ground of the laboratory. It is necessary to study the vibration characteristics of other laboratories and offices because of the large vibration and noise. On this basis, appropriate vibration isolation measures are taken. The vibration of hydraulic system mainly includes two aspects: the vibration of mechanical structure and the vibration caused by the working of liquid medium. According to the vibration of hydraulic system in laboratory. It is determined that the vibration of FESTO hydraulic system is mainly mechanical structure vibration, but the vibration produced by liquid medium is relatively weak. The research shows that the main vibration form of FESTO hydraulic system is the linear forced vibration caused by simple harmonic force. The dynamic model of single degree of freedom harmonic forced vibration of hydraulic system is established in this paper. The vibration test program is designed by using LabVIEW8.5 software, and the vibration characteristic of the system is tested by selecting the corresponding test equipment. On the basis of the test results, the rubber vibration isolator is designed, which is used for the vibration isolation and vibration reduction of hydraulic system, and the performance parameters of the rubber isolator are analyzed and calculated. By comparing the vibration and noise level of the hydraulic system before and after vibration isolation, it is proved that the rubber vibration isolator has a certain isolation effect, and the vibration and noise are greatly reduced. It has had little impact on adjacent laboratories and offices.
