Annotation

The work is devoted to the development of a model and algorithm for calculating the vibration parameters of the crankshaft, taking into account the mutual influence of vibration types (longitudinal, bending, torsional). The crankshaft model performs a complex motion: rotation at a constant angular velocity around an axis passing through the support bearings (transfer motion), and forced oscillations about this axis. The solution to the problem is sought in the form of a superposition of solutions obtained for each of the indicated movements. When developing a mathematical model, the kinetostatic method was used. This approach made it possible to modify the previously developed model by introducing additional elements into its composition that automatically. The calculation algorithm is based on the partial response method in its discrete version. For the modified model, a set of dependencies was derived that reflect changes in partial responses and partial parameters when passing through additional elements. Keywords: quasi-one-dimensional model, inertia-stiffness characteristics, partial responses, vibration parameters, propeller rotation.
