Similarity formula when machining impellers of centrifugal pumps

Kondratiev A.S.


It is shown that during machining of centrifugal pumps impellers the condition of geometric similarity is not fulfilled, that’s why comparable pumps are not geometrically similar. It is shown, that according experiments ratio of motion of such pumps is proportional to the diameter of machined and not-machined impellers.

HIL-simulation as an instrument for elaboration of automotive drivetrains with wheels torques distribution

Kulikov I.


The paper gives an analysis of the Hardware-in-the-Loop (HIL) simulation applied to development and elaboration of drivetrains with separate drives to individual wheels or axes. First, features and functions of such drivetrains are shortly described. Further, the most difficult tasks emerging during development of these drivetrains are analyzed along with ways that HIL offers to resolve these tasks. For that analysis, the paper gives essential principles of vehicle simulation by means of a test rig and HIL-technique. As examples of pertinent drivetrains and HIL-solutions the paper surveys developments of world-leading companies i.e. LuK, Froude Hofmann and Horiba as well as Russian research organizations: Moscow State University of Mechanical Engineering (MAMI), Central scientific research automobile and automotive engine institute «NAMI» and NAMI-Service.
