【摘要】：高空作業(yè)車(chē)是當(dāng)今廣泛應(yīng)用在市政、園林、電力、消防、航空等行業(yè)的專(zhuān)用設(shè)備之一。隨著我國(guó)經(jīng)濟(jì)的迅猛發(fā)展,對(duì)其的需求量越來(lái)越大,對(duì)其性能的要求也越來(lái)越高。但是目前國(guó)內(nèi)高空作業(yè)車(chē)的開(kāi)發(fā)能力、產(chǎn)品規(guī)模和質(zhì)量都與國(guó)外有相當(dāng)大的差距。而隨著我們加入WTO,高空作業(yè)車(chē)在國(guó)內(nèi)國(guó)際市場(chǎng)上競(jìng)爭(zhēng)更激烈。因此,研究和探索高空作業(yè)車(chē)的動(dòng)力學(xué)特性和作業(yè)平臺(tái)的殘留振蕩的抑制,以便設(shè)計(jì)和生產(chǎn)出作業(yè)高度更高、操作更平穩(wěn)可靠的高空作業(yè)車(chē)是當(dāng)前最為緊迫的課題。 本課題以應(yīng)用廣泛的折疊式高空作業(yè)車(chē)作為研究對(duì)象,鑒于實(shí)際工況中作業(yè)車(chē)存在的問(wèn)題,首先對(duì)其進(jìn)行了水平面上穩(wěn)定性和作業(yè)穩(wěn)定性分析,研究了一些重要結(jié)構(gòu)參數(shù)對(duì)作業(yè)車(chē)穩(wěn)定性的影響程度。 其次,當(dāng)作業(yè)臂做加速上升或下降運(yùn)動(dòng)時(shí),作業(yè)平臺(tái)會(huì)產(chǎn)生強(qiáng)烈的振動(dòng),因此有必要對(duì)折疊式高空作業(yè)車(chē)進(jìn)行動(dòng)力學(xué)分析。本文運(yùn)用分析動(dòng)力學(xué)法對(duì)折疊式高空作業(yè)車(chē)的作業(yè)平臺(tái)進(jìn)行動(dòng)力學(xué)分析,即運(yùn)用拉格朗日方程法對(duì)作業(yè)平臺(tái)建立起了動(dòng)力學(xué)模型,研究了在Bang-Bang輸入下作業(yè)平臺(tái)的動(dòng)態(tài)特性,運(yùn)用一種魯棒性開(kāi)環(huán)控制方法,即輸入整形方法,對(duì)系統(tǒng)輸入進(jìn)行整形控制,通過(guò)數(shù)字仿真實(shí)驗(yàn)驗(yàn)證了此種方法對(duì)抑制作業(yè)平臺(tái)擺動(dòng)的有效性。 最后,對(duì)基于柔性地基作業(yè)的折疊式高空作業(yè)車(chē)系統(tǒng)進(jìn)行動(dòng)力學(xué)分析,利用拉個(gè)朗日方程法建立了系統(tǒng)的非線性動(dòng)力學(xué)方程。數(shù)值仿真了所考慮的折疊式高空作業(yè)車(chē)系統(tǒng)在作業(yè)時(shí)的擺動(dòng)情況。
[Abstract]:Aerial vehicle is widely used in municipal, garden, electric power, fire fighting, aviation and other industries. With the rapid development of economy in our country, the demand for it is increasing and the demand for its performance is becoming higher and higher. However, the development ability, product scale and quality of domestic aerial vehicle are far from those of foreign countries. And as we join WTO, aerial vehicles in the domestic and international market more fierce competition. Therefore, it is the most urgent task to study and explore the dynamic characteristics of the aerial vehicle and the suppression of the residual oscillation of the operating platform in order to design and produce the aerial work vehicle with higher operating height and more stable and reliable operation. In this paper, the foldable aerial work vehicle is widely used as the research object. In view of the problems existing in the actual working conditions, the stability and operation stability of the vehicle in horizontal plane are analyzed firstly. The influence of some important structural parameters on the stability of the operating vehicle is studied. Secondly, the platform will produce strong vibration when the arm moves up or down, so it is necessary to analyze the dynamics of the folding aerial vehicle. In this paper, the analytical dynamics method is used to analyze the operation platform of folding aerial vehicle, that is, the Lagrange equation method is used to establish the dynamic model of the platform, and the dynamic characteristics of the platform under the input of Bang-Bang are studied. A robust open-loop control method, I. E. input shaping method, is used to control the input of the system. The effectiveness of the method is verified by digital simulation. Finally, the dynamic analysis of the folding aerial vehicle system based on flexible foundation operation is carried out, and the nonlinear dynamic equation of the system is established by using the Lagrangian equation method. The swing of the folding aerial vehicle system is simulated numerically.
