Substantiating a method for computer analysis of the stress-strain state of the tubbing erector manipulator mechanism

Purpose. To develop and substantiate a method for computer analysis of the stress-strain state that occurs in tubbing erector manipulator mechanism with several degrees freedom, using modern computing complexes based on finite-element method. Methodology. The research uses software complexes, help which calculation-theoretical apparatus has been created, is intended calculating dynamic static loads occur elements mechanism. results modeling parts nodes this mechanism, obtained SolidWorks Motion Simulation programs, have compared. errors these estimated. Findings. effectiveness proposed method, combination applications, particular, Simulation, proven example most complex design UT62 Originality. For first time, type developed substantiated. essence initially, application, laws motion motors are set. erecting process itself divided into discrete moments time selection stress fields calculated determination maximum equivalent stress, Setup tool. change stresses during cycle analyzed, if it necessary to refine data, step reduced. Specific information about part data imported from program gravitational inertial forces Practical value. can be used mechanisms different complexity, domestic erectors.
