【摘要】：隨著科技的高速發(fā)展和時(shí)代的日新月異,可控機(jī)構(gòu)作為一種將機(jī)電控制和機(jī)械技術(shù)相結(jié)合的新興產(chǎn)物,成為了機(jī)構(gòu)學(xué)重要的研究領(lǐng)域。可控機(jī)構(gòu)式挖掘機(jī)相對(duì)于液壓挖掘機(jī)不但零件壽命較長、不會(huì)漏油、可靠性較好,而且同樣可以靈活完成各種挖掘動(dòng)作。型綜合是機(jī)構(gòu)設(shè)計(jì)的重要環(huán)節(jié),本文以一個(gè)的三自由度可控機(jī)構(gòu)式挖掘機(jī)為對(duì)象,采用開放副閉合的方法對(duì)其進(jìn)行型綜合,得到80種新型可控機(jī)構(gòu),然后對(duì)選取的挖掘機(jī)構(gòu)進(jìn)行運(yùn)動(dòng)學(xué)分析、動(dòng)力學(xué)分析以及虛擬樣機(jī)仿真分析。總體來說,本文主要完成了以下的研究工作：(1)針對(duì)現(xiàn)有的三自由度可控機(jī)構(gòu)式挖掘機(jī)為對(duì)象,對(duì)挖掘機(jī)結(jié)構(gòu)進(jìn)行了具體分析,然后采用開放副閉合的方法進(jìn)行型綜合,綜合出98種運(yùn)動(dòng)鏈,再通過觀察,對(duì)98種運(yùn)動(dòng)鏈采取特定的設(shè)計(jì)要求從而進(jìn)行篩選,最后得到80種符合要求的新型三自由度可控機(jī)構(gòu),并且對(duì)其中6個(gè)符合要求的可控機(jī)構(gòu)進(jìn)行具體化得到6個(gè)可控機(jī)構(gòu)式挖掘機(jī)構(gòu)型。(2)通過拆分成四桿機(jī)構(gòu)、五桿機(jī)構(gòu)和三桿組機(jī)構(gòu)來研究機(jī)構(gòu)的位置關(guān)系,并進(jìn)行運(yùn)動(dòng)學(xué)正解和逆解分析,最后進(jìn)行正逆解數(shù)值分析。(3)對(duì)可控挖掘機(jī)構(gòu)進(jìn)行奇異性和工作空間邊界條件分析,運(yùn)用動(dòng)態(tài)靜力學(xué)方法將瞬時(shí)慣性力系轉(zhuǎn)化為靜力系,建立該機(jī)構(gòu)動(dòng)態(tài)靜力學(xué)模型。(4)使用Adams虛擬樣機(jī)技術(shù)建立模型,對(duì)機(jī)構(gòu)分別進(jìn)行動(dòng)力學(xué)分析、運(yùn)動(dòng)學(xué)正逆解分析。
[Abstract]:With the rapid development of science and technology and the rapid development of the times, controllable mechanism, as a new product which combines mechanical and mechanical control and mechanical technology, has become an important research field of institutional science. Relative to hydraulic excavator, the controllable mechanism excavator not only has a long life, but also can not leak oil, it is reliable, and it can be also flexible. In this paper, a three degree of freedom controllable mechanism type excavator is taken as the object, and the open sub closure method is used to Synthetist the excavator with 80 kinds of new type of controllable mechanism. Then the kinematics analysis, dynamic analysis and virtual prototype imitation of the selected mining mechanism are carried out. In general, this article mainly completed the following research work: (1) in view of the existing three degree of freedom controllable mechanism excavator as the object, the structure of the excavator is analyzed concretely, and then the open auxiliary closed method is used to synthesize and synthesize 98 kinds of transport chain, and then the 98 kinds of sports chains are set up by the observation. 80 kinds of three degree of freedom controllable mechanism which meet the requirements are obtained, and 6 controllable mechanisms are made to get 6 controllable mechanism type excavator configurations. (2) the position relationship of the mechanism is studied by splitting into four bar mechanism, five bar mechanism and three bar organization. Numerical analysis of positive and inverse solutions, and numerical analysis of positive and inverse solutions. (3) analysis of singularity and working space boundary conditions for controllable excavating mechanism, using dynamic statics to transform the instantaneous inertial force system into static system and establish the dynamic statics model of this mechanism. (4) using Adams Virtual Prototype Technology to establish the model and the mechanism of the mechanism, The dynamic analysis is carried out, and the kinematics positive and inverse solutions are analyzed.
