Nonlinear vibration issues are of great importance in physics, mechanical structures and other engineering research. Vibration response, stability, and frequencies are the main components of a system's vibration check. Therefore, investigating the effect of different parameters in these sections can be an important step in the design process. In recent years, much research has been done on nonlinear vibrations, and analytical and numerical methods have been used to solve complex nonlinear equations. Equipment and the use of marine structure laboratories for the practical study of the dynamic behavior of vessels require large expenditures, so in order to advance computer science, several software's have been developed and used to model and perform dynamic analysis. In this paper, the mass of the shaft, the motor assembly and the impeller are each examined as a centralized mass and are modelled by ANSYS software. Then, by extracting vibrational equations along the shaft axis and multi-objective optimization with response surface method (RSM), the comparison of the results of this method with the work of other researchers shows that this method has a good accuracy.

“…A method for treating the monitoring data on fuel consumption depending on the air temperatures at the engine intake with regard to the influence of changes in engine loads was presented in [10,30]. That method is modified by using for treatment of monitoring data the correlations from the generalized methodology presented in [39].…”

The fuel efficiency of gas engines is effected by the temperature of intake air at the suction of turbocharger. The data on dependence of fuel consumption and engine electric power on the intake air temperature were monitored for Jenbacher gas engine JMS 420 GS-N.LC to evaluate its influence. A waste heat of engine is rejected for heating water to the temperature of about 90??. The heat received is used in absorption lithium-bromide chiller to produce a cold in the form of chilled water. A cooling capacity of absorption chiller firstly is spent for technological needs and then for feeding the central air conditioner for cooling the ambient air incoming the engine room, from where the air is sucked by the engine turbocharger. The monitoring data revealed the reserves to enhance the efficiency of traditional cooling system of intake air by absorption chiller through deeper cooling. This concept can be realized in two ways: by addition cooling a chilled water from absorption chiller to about 5-7?? for feeding engine intake air cooler or by two-stage cooling with precooling ambient air by chilled water from ACh in the first stage and subsequent deep cooling air to the temperatures 7-10?? in the second stage of intake air cooler by using a refrigerant as a coolant. In both cases the ejector chiller could be applied as the most simple in design.

“…Одним з найбільш ефективних напрямків підвищення паливної ефективності енергетичних установок на базі газотурбінних двигунів (ГТД) і двигунів внутрішнього згоряння (ДВЗ) є комплексна утилізація високо-та низькопотенційної теплоти [1]. Особливо цікавим з цієї точки зору є застосування тепловикористовуючих холодильних машин в установках комбінованого виробництва енергії (когенерація, тригенерація) як для суднової так і для стаціонарної енергетики [2]. Слід відмітити, що холодильні машини такого типу можуть забезпечувати виробництво холоду різного призначення, наприклад, для систем технологічного або комфортного кондиціювання повітря з одного боку [3], а також для енергетичних потреб теплового двигуна (ГТД або ДВЗ) енергетич-ної установки (охолодження повітря на вході, проміжне охолодження циклового повітря, охолодження наддувного повітря та інш.)…”

Modern heat-using ejector refrigeration machines used in heat recovery systems for power plants based on gas turbine engines and internal combustion engines have many advantages over absorption refrigeration machines: smaller dimensions and weight; the ability to obtain lower temperatures. However, they are inferior in energy efficiency, and the thermal coefficient is much lower and can be 0.2…0.4. The efficiency of such refrigeration machines largely depends on the choice of the working fluid (refrigerant). Hence the need to choose a refrigerant that would provide the maximum heat factor, and hence the maximum efficiency of heat recovery. Given the relatively low efficiency of the ejector refrigeration machine, the search for a working fluid that will provide, on the one hand, higher thermal coefficients, and on the other hand high environmental friendliness, is one of the promising areas of development of heat recovery technologies in power plants. The study used the software complex developed by the authors to calculate the refrigeration cycles of heat-using refrigeration machines, taking into account the properties of many modern refrigerants, ejector characteristics, as well as basic heat exchangers (condenser, evaporator, generator). The efficiency of ejector refrigeration machines when working on the following working bodies was analyzed: R142b, R134a, R600, R600a, R1234ze(E), R1233zd(E), R1234yf, R227ea, R236fa, R245fa. R142b, R600, R600a, R245fa have the largest values of thermal coefficients. It is established that the most profitable in terms of environmental friendliness (ODP, GWP) and energy efficiency is the use of refrigerant R245fa, which has a condensation temperature range is 25…35 oC and boiling in the evaporator is 0…15 oC thermal coefficient is 0.40…1.03.
