USING IMPROVED DESIGN METHOD OF SHEER STRENGTH OF REINFORCED CONCRETE BEAMS

The analysis of the efficiency of six types of slabs has been carried out, which differed in material, internal form and weight. The comparison and the comparison of the same in size, but different in constructive characteristics and materials of floor slabs are considered and performed.

Computer testing as innovative tool of measuring knowledge of english

In today's active development of information space a global problem appears the education – the quality and relevance of educational information. One way to solve this problem is to use information technology with the latest developments in the computer industry in the educational process. It is clear that computer technology can intensify the learning process, change the overall organization of training and pass from group classes and forms of knowledge control to the individual, automated.

Evaluation efficiency of information provision of innovative projects

Under the effectiveness of information provision of innovative projects should be understood as the optimum correlation between the result of using system of information provision and the spending for it’s purchase, installation, workpiece, exploitation as well as the correspondence of functional characteristics to the defined purpose and objectives. Today there is no single unified approach to evaluation the effectiveness of the implementation of information provision, as there is no industry standard information provision.

Expansion of technological possibilities of zinc-milling lining machines for cutting of conical wheels on the basis of radial-circular method

The paper presents a new method bevel gears cutting. It’s based on the radial-circular generating gear teeth method. Gear cutter is a simple thin mill disc and a process implements a gear cutting machine with the gear rotation. The cutting conditions and parameters in bevel gears machining are calculated. The advantages of the method and the possibility of it’s application are proven.

INNOVATIVE CONTENT FOR ORGANIZING PRODUCTION ACTIVITIES OF INDUSTRIAL ENTERPRISES

The synthesis and coverage of foreign experience in the organization of production at industrial enterprises has a diverse focus and encompasses methods that increase the productivity of their productive activities in various ways. In this context, the Japanese experience of organizing production deserves special attention. The advantages of its application are demonstrated by Japanese companies that are world leaders in terms of achieved product quality, productivity, stock optimization, in-house and other costs.

Gears with Asymmetric Tooth Profiles and New Alternative Method of Their Manufacturing

The article presents a new gears cutting process – radial circular generating method and describes its multiple benefits for manufacturers of transmissions. The overall increase of efficiency is realized due to using a simple tool and the conventional gear tool machine for cutting gears of different types. In particular, this new method was used for cutting gears with the asymmetric profiles of wheel teeth, which allows considerably amplifying power transmission density, increasing load capacity, and reducing size and weight.

Optimization of Structure of Sorting Vibratory Separators

The problem of substantiation of operational efficiency of vibratory separators designed on the basis of vibratory hopper feeders with electromagnetic vibrations exciters and with conic working bowls is considered in the article. The complex of factors influencing the accuracy and productiveness of separation of coins and disk-shaped products on two or more fractions is overviewed. New models of structures for the effective solution of separation problems are proposed.

Justification of Efficiency of Elliptical Gear Train in Device for Speed Changes Management

The article analyses the functioning of epicyclical gear train with closed circuit hydrosystem, where the driving element is the sun gear and driven one is the carrier or vice versa. Control element is the ring gear, which rotates or can be stopped by the closed circuit hydrosystem.
We have conducted a theoretical research of efficiency in such epicyclical gear train. Using the means of computer modelling, we have obtained graphical dependences of the transmission efficiency from its parameters.
