Abstract

Summary.  Raising  of  problem.  Expansion  of  technical  and  technological  capabilities  and  scopes  of  using  of  longitudinal digging  excavators  are  relevant  and  economically  feasible.  There  is  a  need  for  creating  of  double  appointment  machines  for performing  excavation  in  civil  engineering  and  for  fortification  arrangement  of  positions  of  troops.  Formulation  of  the  task  of creating of radically new construction machines  is logical. These machines could be used for digging the  variable width trenches  in frozen and not frozen soil without the  changeovers of working equipment. Known constructions of trench excavators of  native and foreign production are highly focused machines. That’s why the scope of using of trench excavators is limited in comparing wi th single-bucket  excavators.  Review  of  published  results  of  researching  of  continuous  action  ground-digging  machines  shows  that working processes of multipurpose ground-digging machines weren’t almost been researched.  Object. On the basis of comparing of the analytical calculations and the experimental research results of the MGDM`s rotor working equipment`s physical model establish the value  of the correction factors for the calculation of main vector`s components of soil-digging forces by rotor working body of the multipurpose ground-digging machine.  Conclusion.  The value of the correction factors for the calculation of the main vector`s components of soil-digging forces by rotor working body of the multipurpose ground-digging machine that could be used during the design calculations of the working equipment are established.
