【摘要】：采用鍵合圖方法對直線驅(qū)動鉸鏈機構(gòu)進行動力學(xué)建模時,傳統(tǒng)的虛擬彈性鉸接點或拉格朗日乘子法會引入新的動態(tài)環(huán)節(jié)導(dǎo)致出現(xiàn)剛性問題,勢流關(guān)系混亂難以規(guī)范化和模塊化.提出了一種針對該機構(gòu)的鍵合圖因果關(guān)系分類整理方法,通過元件接口勢流因果分析及元件間連接規(guī)則整理兩個方面,分類為液壓缸、主部件和連桿三種元件,并分別統(tǒng)一各鉸接點勢流因果關(guān)系接口為根點、外力頂點、力輸出點和負載點,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)范方法以簡化建模過程.最后反鏟挖掘機的建模及仿真示例證明了本方法對于工程機械的常見工作機構(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.
