| 摘 要： | Joukowsky's Lever Method is the method used to find out the equilibrant and balancingmoment of various mechanisms.The advantage of this method is to save the complicated processof finding out the reactional forces in kinematic pairs.But,the method is only limited to thosemechanisms composed of rigid bar linkages and with negligible friction.In practical cases,hydropneumatic elements and spring constraints may be included in the mechanism;and alsowith the development of high load,high speed and high accuracy of mechanism,the friction maynot be neglected.So,the authors have tried to develop the Generalized Joukowsky's LeverMethod,which can be used to find out the equilibrant and balancing moment of the mechanismwhen the hydropneumatic elements and spring constraints are included and the friction inkinematic pairs has to be considered.Three examples are here analyzed to show the applicationsof this method.

| Abstract: | Joukowsky's Lever Method is the method used to find out the equilibrant and balancing moment of various mechanisms.The advantage of this method is to save the complicated process of finding out the reactional forces in kinematic pairs.But,the method is only limited to those mechanisms composed of rigid bar linkages and with negligible friction.In practical cases, hydropneumatic elements and spring constraints may be included in the mechanism;and also with the development of high load,high speed and high accuracy of mechanism,the friction may not be neglected.So,the authors have tried to develop the Generalized Joukowsky's Lever Method,which can be used to find out the equilibrant and balancing moment of the mechanism when the hydropneumatic elements and spring constraints are included and the friction in kinematic pairs has to be considered.Three examples are here analyzed to show the applications of this method. |
