Occupational safety is one of the important aspects of the organization of work in production. Domestic machines and units used in the food industry do not yet allow to exclude the impact of harmful and dangerous production factors, to make the work of employees safe. In this context, it is important to study active and passive methods of noise and vibration suppression, their effectiveness in ensuring normalized working conditions of workers on the example of a specific production. Existing research, as a rule, focuses on one criterion when choosing protection methods. However, an integrated approach is advisable in solving this problem. The purpose of this study was to choose a rational method of protecting personnel from the effects of noise and vibration based on the economic justification of effective technical solutions. The obtained research results make it possible to take into account the criteria for evaluating the validity and acceptability of choosing a particular protection method, including from the standpoint of technical and economic calculation, when designing a security system. The above study showed the expediency of import substitution in the food and beverage industry, as well as the correlation between the introduced protection systems and an increase in the level of safety. The given algorithm of the feasibility study has the properties of scale and generality. It can be successfully implemented when choosing methods of protection from the effects of other harmful production factors found in various industries.

The article examines the influence of observance of the frame dome-shaped roofs assembly technology on the quality of the completed object. This theme is relevant enough, as the building roofs, constructed in accordance with the aforementioned technology, are often found in modern business clusters. It`s natural that prospective investors are interested in perfect quality and seamless service properties of similar construction object designs. The authors considered features of the frame dome-shaped designs construction and assigned its pros and cons; the review of the technical investigation of one of the shopping centers was conducted with purpose of showing the consequences of inaccurate observance of the specified designs installation technology. Subject to facility technical investigation results, recommendations for the safety operation of dome support structures were given.

The parameters of the structure of the building material, including sulfur, depend on a large number of prescription and technological factors. This paper presents the experimental dependences of the average density and porosity of the sulfur composite material on the volume degree of filling, the specific surface of the filler, the concentration of the appret and the time of isothermal exposure. It is established that the dense sulfur composites obtained with silica filler with a specific surface area of 180 m2/kg, processed 30%-and 50%-s ' solution of rubber and subjected to isothermal aging for 2...3 hours

This paper considers basic element of device of energy storage which is a piezoelectric generator (PEG) of cylindrical form with the attached inertial mass. A finite element modeling of the device operation is carried out during active load in the external circuit. The main purpose of the operation is to compare the output potential and frequency characteristics of the device known in the literature models of systems with concentrated parameters. On the basis of these models, we can receive the analytical dependence of parameters of PEG with its geometric characteristics and mechanical properties of the used materials. However, the question of the range of applicability of these formulas is still open. In this paper, based on the numerical analysis of finite element models of PEG in package ANSYS, we obtained comparison with the analytical formulas that show the values of some parameters of simplified models and set the boundaries of their applicability.
