This paper deals with the issue of marine diesel generator unsteadiness due to the difference between an electrical propulsion system power consumption and a marine power plant generation. To describe this issue the seagoing tug “Project 745” was taken as an example. The reasons of power mismatching have been described in the following paper. The ways of this problems solving have been studied. This issue is relevant for all ships where the rated power of electric propulsion system is comparable to the power of marine sources of electrical energy.

The work suggests an oblong ellipsoid method for implementing tasks to choose effective values of controlled parameters, analyze risks of making ineffective solutions and risks of omissions of effective solutions in process control. This method is considered as the basis for making an expert system to support solutions on process efficiency control.

Relevance of the work is conditioned by necessary improvement of the design methods for irregular shape objects. The paper presents the analysis of environmental design object arrangement according to the biological object. There used the methods of biologically based design and the methods of mathematical modeling (for load calculation). The article demonstrates that the similarity method of biological and technical objects can be used at the first design phase of the technical object shape. Use of materials and technologies is justified for winding stairs production, which includes a biological object. The principles of bionic aesthetics being the basis for design are substantiated.

Based on known theoretical results, the paper presents a detailed mathematical model for surface roughness and injection of gaseous products generated from thermochemical destruction of a carbon-fiber-reinforced polymer. Ablation through a rough surface has various effects on the rate of heat transfer in thermal protective materials. The numerically calculated data were compared with known data.

As a result of computational and experimental study the regularities of wear of the grinding wheel working surfaces in the process of double disk grinding of bearing rings ends have been established. Adequacy of mathematical and computer models has been confirmed by a satisfactory agreement of computer simulation results and experimental data. The established regularities have laid the basis for a new method of making the working surface of grinding wheels.

Application of the ray series method is studied on the example of the one-dimensional problem of the impact load on the boundary of a nonlinear elastic cylindrical layer. Particular attention is paid to the construction of ray series for the shock waves formed within the layer as a result of the interaction of the initial shock waves.

One of the main problems of studying the process of cutting of materials and tool wear deals with studying both the kind and character of contact interaction between the treated metal and the working surfaces of the tool. Without clear view of both the character of contact interaction and the patterns of kinematics, deformation, and thermal processes in contact zones over a full range of cutting speeds, it is impossible to make correct conclusions on the nature and common patterns of tool wear.
