Study on Nonlinear Model of Dynamics of a System ‘Extruder Elastic Auger Working Body’

The model of dynamics of a system ‘extruder elastic auger working body’ is developed. The design of an extruder elastic screw working body is worked out. The article provides the proposition of calculation technique for determining of the theoretical dependences that would analyse the laws of amplitude changing and oscillation phase of a system ‘elastic auger working body’ in the non-resonant case. It also provides analytical dependences determining the characteristic features of different geometrical parameters of an extruder working body.
