Authors: Maslensky V V , Bulygin Yu I , Temirkanov A R , Shchekina E V
Published: December 2020

The aim of the study is to analyze and select a rational method for calculating heat suply from solar radiation for the correct determination of the thermal load on the climate system of the cabin of a mobile machine. The correct calculation of this component of the heat balance allows to correctly determine the power of the climate system of the cabin, which ensures optimal working conditions at the workplace of operators of mobile machines. To achieve the goal, the most common methods for calculating solar radiation were described and analyzed in detail, and the most accurate ones were recommended. The more laborious Bogoslovsky method (taking into account the time of the day) can be recommended for automated calculations in Excel, and the Hamburg method (taking into account the horizon sides) – for comparative evaluative engineering calculations. When carrying out “in-depth” model calculations and accounting for solar radiation, the ASHRAE method is explicitly suitable, which has two important advantages: it takes into account the solar factor in relation to a specific type of glazing and is adapted for automated calculations in ANSYS FLUENT.

Authors: Beskopylny A , Meskhi B , Veremeenko A , Isaev A
Published: December 2020

The article deals with the problem of assessing the influence of the boundary conditions for fixing a plate with a welded seam on the stress-strain state during hardening with a ball-rod hardener. Welded joints are currently a trouble spot of the destruction of heavily loaded structures. Analysis of the microstructure and strength characteristics of the welded joint of 09G2S steel showed that in the fusion and heat-affected zones, the strength decreases due to temperature effects. The problem of modeling the strengthening of a welded joint with a ball-bar hardener under various conditions of plate fixing: with a free and fixed lower face is considered. The FEM model is constructed and the comparison of the conditions of plate fixation is carried out, which makes it possible to assess the degree of hardening and to assess the residual stresses after hardening treatment. It is shown that strengthening of a plate with a free bottom face significantly changes the stress-strain state of the plate and redistributes residual stresses to the weld zone, where strengthening is undesirable.

Published: December 2020

The introduction of high-grade mineral additives in feed allows to get balanced rations for livestock and poultry. It is known that the most effective use of them when feeding in the composition of feed. However, today, in real conditions, farms receive less than 30% of the required amount of chemical feed additives with compound feed. In addition, the outlined tendency towards a decrease in the production of compound feed due to the lack of grain and protein components indicates that the feed industry is not entirely able to solve this problem. Adequate feeding of dairy cows assumes an optimal intake of all essential nutrients in the body, which contributes to good health, normal reproduction and high productivity. A significant reduction in the energy deficit during this period can be achieved by introducing energy-rich feed concentrates, grass cutting and grass flour of high quality, root crops, etc. into the diet. The higher the milk yield of cows, the more energy should be in one kilogram of dry matter of the diet. This article proposes a technology for producing a protein-vitamin feed concentrate for full-value feeding of farm animals. To solve the fodder problem in animal husbandry, it is necessary to more widely use substandard raw materials, organic waste, ensuring their utilization within the framework of waste-free technology.

Aluminum is one of the most widely used materials in the industrial sector after iron and steel. Aluminum can be combined with other metals such as Cu, Mg, Si, Mn, Zn, Ni, to add the characteristics of aluminum that you want to improve. Increased strength through the rolling process which varies the cross-section reduction (5%, 10%, 15%, and 20%), is intended to find out how much the strain hardening effect on the rolling process on the mechanical properties of Al-Cu alloys Based on the results of the study, it was found that plastic deformation through the rolling process can increase hardness, strength, and increase metal shaking. In Al-Cu alloy series 2024, the optimal reduction is 15% of the thickness of a 10 mm plate with a rolling temperature of 200 ° C. At the recrystallization temperature of the Al-Cu alloy series 2024, there is still a mechanism of metal strengthening due to strain hardening.

There are still many high-rise building managements that carried out in a conventional method and do not involve the latest ICT. So that the maintenance implementation is not running effective and efficient which causes the maintenance performance of the building is not optimal. Therefore, it is necessary to identify elements and indicators that can be used to evaluate the implementation of e-maintenance in high-rise buildings in terms of both effectiveness and efficiency. This study aims to identify the elements and indicators in the implementation of e- maintenance that affect the performance of maintaining high-rise buildings using the literature study and Delphi methods. First, the elements and indicators were obtained by the literature study and then were validated by the experts. As for the research produced five elements that affect the performance of high-rise building maintenance, those are maintenance policies (planning and development, implementation, systems, and improvement): 15 indicators; WBS (scope and value): 7 indicators; guidelines (procedures and methods, program, tools and equipment): 11 indicators; information systems (organization, management, information technology): 15 indicators, and BIM (utilities, information, functional, technical, and organizational/legal criteria): 9 indicators. The building maintenance performance obtained (failure rate, downtime, cost, and service quality) consists of 14 indicators.

PT. ZYX is a textile and garment industry. The important department of this company is the knitting department that knits yarn into cloth, which will be used for the garment production of garment. Companies often experience shortages of stock to conduct production activities to meet consumer needs. In addition, the fluctuate demand sometimes does not match the available resources. This condition lead to the increasing of inventory costs. Based on the existing problems .The aim of this research are forecasting demand with Artificial Neural Network (ANN) method, calculating the production aggregate, controlling the cost of inventory control procurement, and designing a production planning inventory control system. Forecasting results are the input data to calculate the aggregate total production and the total inventory cost. Mixed Strategy is the best solution method for PT.ZYX, with a total cost of Rp 2,435,878,117.86, -. The best aggregate method for PT. ZYX is a mixed strategy method, because it gives the smallest total production cost of Rp 2,355,466,975. The inventory control is classified as dynamic inventory can save cost for 19.27% in RIB 1x1 product; 36.67% in RIB 2X1 product; 2.01% at RIB 5X2 product; 60.52% for single knit product.

Published: December 2020

Measuring dimensions of indoor environment have an important role in construction, whether for calculation of work, or documentation purposes. Humans may introduce errors and make measuring real objects less accurate. Several methods have been developed to reduce this error and one of them is a non-contact measurement that executes according to guideline can minimize this error. Measurement using image-based measurement can reduce human involvement, where Total Station Theodolite (TST) is very dependent on its operator skill and involvement. This study aims to show the differences between image-based and laser-based measurements using TST in measuring the dimension of the indoor environment. Image-based measurement was obtained by taking photos of a few rooms and processed with an open-source software to produce a 3D model. This 3D model then measured to provide measurement for differences comparison. Laser-based measurement was obtained by hiring professional surveyor to measure the rooms with TST. Results from this study can be used as a reference in developing a new method to measure dimension in indoor application. Without hiring professional to measure using photogrammetry in this research, measurement using photogrammetry can get average differences of 0,2593% from measurement using TST.
