The stability and destruction process of laminated plates made of composite material with different numbers of layers without nano-additives and with nanopowders in the binder has been studied. The results of experimental studies of the stability and destruction process of laminated plates made of composite material are presented. Experimental and numerical methods are used to estimate the carrying capacity of laminated plates. A technique has been developed for the experimental study of the deformation and strength properties of composite materials using modern test equipment. It was established that the discrepancies between the values of the critical load of four-layer samples and the critical load of three-layer samples are 2-3%, therefore, to reduce the weight, products from composite materials can be made of three-layer plates. In the ANSYS system, twolayer, three-layer and four-layer plates were modeled. The results of numerical calculation by the finite element method are presented. Comparison of the obtained experimental results with numerical values is made, the possibility of using experimental data on the mechanical behavior of layered composite materials in the design and calculation of protective screen modules is estimated.","PeriodicalId":158920,"journal":{"name":"Proceedings of the International Conference on Aviamechanical Engineering and Transport (AviaENT 2019)","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131680999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The technique is based on scanning a deformed body by a computer tomograph, with further mathematical transformation of the information obtained for its use in the finite element method analyzing the stress-strain state of parts made of composite and heterogeneous materials. Traditionally, the mechanical characteristics of a real deformable solid body are given as an average value, for example, common for the material of the part and obtained during the test of standard samples. The main purpose of the presented technique is, along with improving the accuracy of calculations, the determining of the level of defects in the material and the degree of its impact on the performance of the product as a whole. The method for determining the real change in the mechanical characteristics of the material of deformable solid bodies is based on the use, on the one hand, of the pixel characteristics of raster images scanned by a computer tomograph; on the other hand, the averaged data on the mechanical characteristics of the material obtained as a result of full-scale tests of standard samples are used. The result of this approach makes it possible to simulate these inhomogeneities in the construction of a finite element model of real deformable solid bodies. The developed approach can be applied to any physical principles of scanning, such as x-ray, ultrasonic, laser and etc., as well as for all types of materials when the information obtained as a result of scanning is formed in the form of a digital (raster) image.","PeriodicalId":158920,"journal":{"name":"Proceedings of the International Conference on Aviamechanical Engineering and Transport (AviaENT 2019)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133660930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The surface processing included thermal-chemical treatment (TCT) and surface finishing. Boroaluminizing (joint diffusion with boron and aluminum) was chosen as a TCT method. Steel samples were covered by a treatment paste, containing boron carbide, aluminum and sodium fluoride powders. The exposure time was 2 hours and the treatment temperature 950°C and 1050°C. The surface finishing was carried out by an elbor grinding tool to coordinate grinding on a vertical milling machine. The diffusion layers with a composite structure were formed on top of the steel as a result of TCT at 1050°C. Processing at 950°C resulted in a diffusion layer formation with layered structure. The surface roughness after boroaluminizing have increased from initial Ra 1.5 μm to Ra 4 μm after 950°C TCT and to Ra 7.7 μm after 1050°C TCT. The roughness increase was due to surface reactions with air components, such as oxygen and nitrogen, as well as their penetration to the upper zones. Applying surface finishing as a final mechanical operation (FMO) resulted in roughness reduction from the above mentioned values to Ra 0.09 μm to Ra 0.43 μm, respectively. In addition, the upper redundant zone of the layer was removed with no damage done to the inner zones by means of FMO. The provided surface quality ensures sufficient operational properties of the machine parts and details made of this particular steel.

This article presents a study of operability of the forty MAN F2000 trucks used in Yakutia for long-haul transport. The systems were identified that limit reliability of these vehicles in the severe operation conditions of the North. These are an engine, suspension and brake system. Regularities of changes in the main operability parameters (operating time to failure and operating time between failures) of these systems and truck as a whole were investigated. Regression models of dependences of the operating time between failures on truck mileage for the engine, the suspension and brake system show a significant decrease in this operating time with the increase in the mileage. Taking into account this decrease, an improved technique of calculating the planned repair number for the systems and parts of automobiles, based on statistical information about the failures of these assembly units in the specific operation conditions is proposed. This technique can be used when planning the repairs of the vehicles with the different mileage and calculation of the required number of the spare parts.
