【摘要】:近些年來(lái),我國(guó)旋挖鉆機(jī)取得了較快發(fā)展,但是相對(duì)于國(guó)外,國(guó)內(nèi)的旋挖鉆機(jī)在關(guān)鍵部件和核心技術(shù)方面跟國(guó)外相比還有一定的差距,我國(guó)旋挖鉆機(jī)的發(fā)展任重道遠(yuǎn)。旋挖鉆機(jī)功率大,所以其節(jié)能性的好壞直接影響該設(shè)備的經(jīng)濟(jì)性和可靠性,由于世界能源危機(jī)的爆發(fā),節(jié)能技術(shù)被各個(gè)行業(yè)所重視。本文將以XR220D旋挖鉆機(jī)作為研究對(duì)象,對(duì)其發(fā)動(dòng)機(jī)、液壓系統(tǒng)及其負(fù)載的匹配進(jìn)行理論和試驗(yàn)研究。 主要完成下面的工作: 1、闡述了國(guó)內(nèi)、外旋挖鉆機(jī)節(jié)能控制的研究現(xiàn)狀與發(fā)展趨勢(shì),并分析旋挖鉆機(jī)鉆孔作業(yè)的特點(diǎn)。 2、在闡述旋挖鉆機(jī)作業(yè)鉆孔時(shí)工藝特點(diǎn)以及動(dòng)力系統(tǒng)工作原理的基礎(chǔ)上,得出旋挖鉆機(jī)能量損失的原因,并根據(jù)現(xiàn)行節(jié)能控制技術(shù)的研究現(xiàn)狀,提出合理的控制策略,即發(fā)動(dòng)機(jī)分工況控制以及基于轉(zhuǎn)速感應(yīng)的極限負(fù)荷控制綜合節(jié)能控制,從而達(dá)到了使發(fā)動(dòng)機(jī)輸出功率與負(fù)載所需功率匹配的目的。 3、針對(duì)發(fā)動(dòng)機(jī)的轉(zhuǎn)速感應(yīng)控制的節(jié)能控制策略,,建立其相應(yīng)的數(shù)學(xué)模型,采用PID控制算法,既可以減少對(duì)發(fā)動(dòng)機(jī)油門的頻繁調(diào)節(jié),同時(shí)又抑制了發(fā)動(dòng)機(jī)轉(zhuǎn)速的劇烈波動(dòng)。而對(duì)變量泵極限負(fù)荷控制和發(fā)動(dòng)機(jī)轉(zhuǎn)速感應(yīng)控制相協(xié)調(diào),消除發(fā)動(dòng)機(jī)的功率儲(chǔ)備,從而達(dá)到發(fā)動(dòng)機(jī)與液壓系統(tǒng)功率傳遞時(shí)的匹配。 4、基于建立的數(shù)學(xué)模型,以及模糊控制算法,應(yīng)用MATLAB—Fuzzy工具箱設(shè)計(jì)控制器。對(duì)該模糊PID控制系統(tǒng)進(jìn)行MATLAB仿真分析,證明模糊控制的優(yōu)越性。 5、以XR220D型旋挖鉆機(jī)為對(duì)象,對(duì)該節(jié)能控制系統(tǒng)進(jìn)行試驗(yàn),驗(yàn)證該控制系統(tǒng)的有效性。
[Abstract]:In recent years, China's rotary drilling rig has made rapid development, but compared with foreign countries, domestic rotary drilling rig has a certain gap compared with foreign countries in key components and core technology. The development of rotary drilling rig in China has a long way to go. The power of rotary drilling rig is large, so its energy saving quality directly affects the economy and reliability of the equipment. Because of the outbreak of the world energy crisis, Energy saving technology has been paid more attention to in various industries. This paper will take XR220D rotary drilling rig as the research object, and carry out theoretical and experimental research on the matching of engine, hydraulic system and its load. The main tasks are as follows:. 1. The research status and development trend of energy saving control of external rotary drilling rig at home and abroad are described, and the characteristics of drilling operation of rotary drilling rig are analyzed. 2. On the basis of expounding the technological characteristics of rotary drilling rig and the working principle of power system, the causes of energy loss of rotary drilling rig are obtained, and the reasonable control strategy is put forward according to the current research situation of energy saving control technology. That is to say, the engine control based on sub-working condition and the limit load control based on speed induction can achieve the purpose of matching the engine output power with the power required by the load. 3. According to the energy-saving control strategy of engine speed induction control, the corresponding mathematical model is established and the PID control algorithm is adopted, which can reduce the frequent adjustment of engine throttle. At the same time, the violent fluctuation of engine speed is restrained, and the limit load control of variable pump and the induction control of engine speed are coordinated to eliminate the power reserve of the engine, so as to match the power transfer between engine and hydraulic system. 4. Based on the established mathematical model and fuzzy control algorithm, the controller is designed by using the MATLAB-Fuzzy toolbox. The MATLAB simulation analysis of the fuzzy PID control system proves the superiority of the fuzzy control. 5. Taking the XR220D rotary drilling rig as the object, the energy saving control system is tested to verify the effectiveness of the control system.
