Optimal control of a hybrid powerplant based on a balance of ecological and fuel efficiency factors
Authors: Kulikov I A , Selifonov V V , Filonov A I
Published: April 2022

In a hybrid electric vehicle (HEV), IC engine can be operated independently (to a certain extent) of vehicle's speed and power demand. Therefore, there is a substantial flexibility in adjusting HEV's fuel consumption and emissions by varying ICE's operating point. Due to high complexity and non-linearity of hybrid powertrain's characteristics it is necessary to use some mathematical tool to derive an optimal combination of ecological and energy consumption properties of HEV. It is generally accepted that dynamic programming (DP) is well suited for such a task. A DP routine based on the HEV's model was developed and implemented in MATLAB/Simulink environment. A number of runs were executed. Results have revealed an apparent trade-off between fuel effectiveness of HEV and NOx emissions. Based on comprehensive analysis of results, certain ways to deal with this trade-off were offered.

Authors: Maximov Y V , Ankin A V , Vetrova E A
Published: April 2022

The paper examines the combined method of cutting-deforming machining of quill cylinder type nonrigid parts, which increases productivity, quality of machining and working accuracy. The basic feature of the method is that the machining process is accompanied with tensional and bending oscillations caused by geometrically induced errors in the workpiece cross-section, setting errors and various static and dynamic tuning errors of cutting and deforming tools (for example, the static tuning error of structural elements location of processing unit). On the basis of analysis of expressions for resultant error and oscillation equation the authors obtained formula which determines actual cutting depth and lateral force on the part when cutting. On analyzing the alternation of cross section of tube on the example of single-pass part cutting (with maximum transverse force) it was found that in the process of cutting the cross-section of the tube is deformed by negligible quantity.
