【摘要】:隨著單鋼輪振動(dòng)壓路機(jī)技術(shù)的不斷發(fā)展,人們對(duì)單鋼輪振動(dòng)壓路機(jī)工作可靠性、操作舒適性以及作業(yè)質(zhì)量的要求也越來越高。單鋼輪振動(dòng)壓路機(jī)的減振系統(tǒng)不僅影響著整機(jī)操作舒適性,而且也對(duì)作業(yè)質(zhì)量與整機(jī)可靠性有重要的影響。雖然減振系統(tǒng)對(duì)單鋼輪振動(dòng)壓路機(jī)整機(jī)性能的影響受到了一些單鋼輪振動(dòng)壓路機(jī)生產(chǎn)廠家的重視,但關(guān)于如何提升減振系統(tǒng)性能尚無成熟的系統(tǒng)理論和方法。 論文從研究減振系統(tǒng)綜合性分析出發(fā),主要分析了減振系統(tǒng)減振器的受力、材料特性以及減振系統(tǒng)對(duì)整機(jī)性能的影響,得到了部分提高減振器可靠性及使用壽命的方法,并對(duì)良好的減振性能要求以及減振系統(tǒng)的合理優(yōu)化做出了新的定義。 為了更好的研究單鋼輪振動(dòng)壓路機(jī)的減振系統(tǒng),論文對(duì)國內(nèi)外同類型同噸位單鋼輪振動(dòng)壓路機(jī)進(jìn)行了對(duì)比試驗(yàn),經(jīng)數(shù)據(jù)對(duì)比分析發(fā)現(xiàn)國內(nèi)壓路機(jī)減振系統(tǒng)主要存在的問題有機(jī)架偏振與擺振以及駕駛室X方向的振動(dòng)太劇烈。找到存在的問題后,有的放矢建立有針對(duì)性的簡(jiǎn)化模型對(duì)偏振與擺振進(jìn)行了動(dòng)力學(xué)分析,找到了消除機(jī)架偏振,控制上車擺振的方法。 為了進(jìn)一步分析單鋼輪振動(dòng)壓路機(jī)的減振系統(tǒng),以國產(chǎn)試驗(yàn)樣機(jī)為原型,,利用PRO/E、ADAMS、ANSYS建立了單鋼輪振動(dòng)壓路機(jī)—橡膠地面的虛擬樣機(jī)試驗(yàn)?zāi)P,參?shù)調(diào)試完成后進(jìn)行了仿真分析,并與試驗(yàn)測(cè)試數(shù)據(jù)進(jìn)行了對(duì)比,對(duì)比結(jié)果表明:該虛擬樣機(jī)模型具有較高的精度,為下一步減振系統(tǒng)優(yōu)化分析奠定了基礎(chǔ)。 論文最后在前文分析的基礎(chǔ)上對(duì)單鋼輪振動(dòng)壓路機(jī)減振性能的影響因素進(jìn)行了歸納總結(jié),并在此基礎(chǔ)上針對(duì)此虛擬樣機(jī)進(jìn)行了減振系統(tǒng)的參數(shù)優(yōu)化設(shè)計(jì),利用之前的虛擬樣機(jī)模型進(jìn)行了仿真分析,結(jié)果表明:優(yōu)化方案設(shè)計(jì)合理,從而也驗(yàn)證了全文分析的正確性,對(duì)單鋼輪振動(dòng)壓路機(jī)減振系統(tǒng)性能提升有一定的理論指導(dǎo)意義與實(shí)踐應(yīng)用價(jià)值。
[Abstract]:With the development of the single wheel vibratory roller technology, the reliability, operating comfort and working quality of the single steel wheel vibratory roller are becoming more and more important. The vibration absorption system of single steel wheel vibratory roller not only affects the operating comfort of the whole machine, but also has an important effect on the working quality and the reliability of the whole machine. Although the effect of vibration absorption system on the performance of single steel wheel vibratory roller has been paid more attention by some manufacturers, there is no mature system theory and method on how to improve the performance of vibration reduction system. Based on the comprehensive analysis of the vibration absorber system, this paper mainly analyzes the force, material characteristics and the influence of the vibration absorber system on the performance of the whole machine, and obtains some methods to improve the reliability and service life of the absorber. A new definition is made for the requirements of good vibration absorption performance and the reasonable optimization of the damping system. In order to better study the vibration absorption system of single steel wheel vibratory roller, a comparative test of the same type of same tonnage single wheel vibration roller at home and abroad has been carried out in this paper. By comparing and analyzing the data, it is found that the main problems of the damping system of the roller in China are the polarization and shimmy of the frame and the vibration of the cab in the X direction. After finding out the existing problems, a targeted simplified model is established to analyze the dynamics of polarization and shimmy, and a method to eliminate the polarization of the frame and to control the swing in the car is found. In order to further analyze the vibration absorption system of single steel wheel vibratory roller, a virtual prototype test model of single steel wheel vibratory roller and rubber ground was established by using PRO/E,ADAMS,ANSYS, and the simulation analysis was carried out after debugging the parameters. Compared with the test data, the results show that the virtual prototype model has high precision, which lays a foundation for the optimization analysis of vibration absorption system in the next step. Finally, on the basis of the previous analysis, the influence factors of the vibration absorption performance of the single steel wheel vibratory roller are summarized, and the parameter optimization design of the vibration absorption system is carried out for the virtual prototype. The simulation results show that the optimization scheme is reasonable and the correctness of the full-text analysis is verified. It has certain theoretical guiding significance and practical application value for improving the performance of vibration absorption system of single steel wheel vibratory roller.
