Abstract

Abstract.  Single-bucket  excavators  improvement  is  closely  associated  with  development  and  introduction  of  their  workflow automatic control systems and  with a robotic excavator creation.  Thereat, at synthesis of an excavator control  system, the robotics approach is widely developed, according to which, the work equipment is considered as spatial manipulator with hydraulic actu ator. The  control  system  of  a  robotic  excavator  has  to  provide  minimum  of  time  of  a  workflow  execution,  carry  out  digging  with maximum accuracy, as it leads to the productivity increase, and to minimize expenditure of energy for working cycle implementation at this. For that, it is necessary able to calculate the trajectory of the excavator manipulator optimum  in terms of energy. As far as the values  of  external  forces,  which  affect  the  excavator  boom,  stick  and  bucket,  depend  significantly  on  their  attitude  position,  the research of dynamic properties of the excavator manipulator at its movement is necessary. Cond ucting such research is the purpose of this work.
