【摘要】：采用鍵合圖方法對(duì)直線驅(qū)動(dòng)鉸鏈機(jī)構(gòu)進(jìn)行動(dòng)力學(xué)建模時(shí),傳統(tǒng)的虛擬彈性鉸接點(diǎn)或拉格朗日乘子法會(huì)引入新的動(dòng)態(tài)環(huán)節(jié)導(dǎo)致出現(xiàn)剛性問(wèn)題,勢(shì)流關(guān)系混亂難以規(guī)范化和模塊化.提出了一種針對(duì)該機(jī)構(gòu)的鍵合圖因果關(guān)系分類(lèi)整理方法,通過(guò)元件接口勢(shì)流因果分析及元件間連接規(guī)則整理兩個(gè)方面,分類(lèi)為液壓缸、主部件和連桿三種元件,并分別統(tǒng)一各鉸接點(diǎn)勢(shì)流因果關(guān)系接口為根點(diǎn)、外力頂點(diǎn)、力輸出點(diǎn)和負(fù)載點(diǎn),使得剛體元件接口的因果關(guān)系得以延續(xù).在此基礎(chǔ)上建立了元件間連接的規(guī)范方法以簡(jiǎn)化建模過(guò)程.最后反鏟挖掘機(jī)的建模及仿真示例證明了本方法對(duì)于工程機(jī)械的常見(jiàn)工作機(jī)構(gòu)均可適用.
[Abstract]:The traditional virtual elastic hinge point or the Lagrange multiplier method will lead to the rigidity problem when the new dynamic link is introduced in the dynamic modeling of the linear drive hinge mechanism by using the bond graph method. A new method is proposed to classify the bond graph causality of the mechanism, which is difficult to standardize and modularized. Through the causal analysis of the potential flow of the component interface and the arrangement of the connection rules between components, two aspects are classified as hydraulic cylinder, main component and connecting rod three components, and the root point, external force vertex, force output point and load point are unify each joint point potential flow causality interface, which make the causality of the interface of the rigid body element continue. On this basis, it is built. The standard method of connection between components is established to simplify the modeling process. Finally, the modeling and simulation examples of the backhoe excavator prove that this method can be applied to common working mechanism of engineering machinery.
