SPECIAL APPROACH FOR A LONG-LENGTH SOLID BALANCING IN THE UNIQUE PLANE OF UNBALANCES CORRECTION AT VERTICAL BALANCING STAND

Abstract

Background. Mass-inertia asymmetry is experimentally verified at the final stage of the module assembly while designing and manufacturing both efficient and reliable power unit for a vehicle. Materials and methods. The work presents a procedure and an algorithm for balancing the conical solid of rotation in the only plane of unbalances correction at a vertical balancing stand. The correction plane used is designed to be located at the end of the solid far enough of its mass-center. Results. Proposed approach provides, in one step of balancing, either bringing parameters of mass-inertia asymmetry of the solid to design values, or diagnosing unattainability of the latter. Conclusions. The efficiency of the approach is proved by the numerical experimental results.
