Shearer’s quadratic curve unloading torque shaft fracture characteristics numerical simulation

[摘要] The type of Shearer's cutting part torque shaft unloading groove has a significant impact on the fracture characteristics and reliability. Shearer's flexible virtual prototype coupling model was established,combined with the actual working condition,loads of the torque shaft were obtained by ADAMS.bilit,the quadratic curve unloading groove of torque shaft crack finite element model was established.combined with fracture mechanics,FRANC3D was used to do numerical simulationand crack propagation analysis,the torque shaft crack's stress intensity factor was obtained,quadratic curve unloading groove of torque shaft's stable propagation were obtained,was 2.2333e5.Combined virtual prototype technology with fracture mechanics,provides a new technology and data support in in the design and research of Machinery and equipment parts.
