The modernisation of old test machines we carried out with respect of ISO26262 standard's approaches and recommendations to perform validation processes. Tested mechanical components were safety critical and they create one complex mechatronics component. In addition to maintaining functional safety, the modernization of set of test machines has brought about better planning and the use of test machines and utilization of machine time. Designed and realised information system as temporary solution was cost effective solution for four years and it prepared the purchasing a new final testing solution in the production plant. The presented modernization solution is also a good example of the cooperation of the university and the production plant.","PeriodicalId":186085,"journal":{"name":"2020 24th International Conference Electronics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129696021","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}

Manufacturers need to preform ATs on the prototype of the product to anticipate its reliability and lifetime. The requirements for higher reliability impose tests of DUT's materials and components in advance. ATs expose products to different stressing environments, which include Electrical Stress, Mechanical Vibration, Temperature Shock, Temperature Cycling, Humidity, and others. An AT profile consists of different parameters, which depend on the DUT, and the most common are: a type of stress, rate of change, stress extreme points. Although these tests are accelerated, they are still time consuming. Furthermore, for large and complex DUTs, the test reliability itself can be doubted due to the involved diversity and uncertainty. In this paper, different experimental methods are applied to optimize the virtual test parameters to obtain reliable results.","PeriodicalId":186085,"journal":{"name":"2020 24th International Conference Electronics","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125744801","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}

IMT are developing at staggering rates and mobile operators always search for new possible frequency bands to expand their mobile and fixed communication networks (MFCN) and 1427 MHz-1518 MHz frequency band is attractive due to the qualified radio propagation conditions. However, this band is already operated by other technologies, such as aeronautical networks, radio relay, broadcasting networks, in the neighbouring countries. Co-channel and adjacent channel electromagnetic compatibility have to be evaluated. Electromagnetic compatibility between ATS and IMT is one of the most sensitive issues regarding the decision to identify this band to IMT.

The output current control in synchronous rotating coordinate system is adopted during grid-tied operation. The droop control is used during stand-alone parallel operation. In order to verify the design and control, a 500 kW PCS prototype was built and tested. The experiments show that the prototype has good performance and high working stability, including output current or voltage THD, efficiency, steady state, transition between grid-tied and stand-alone mode etc. The output current control and droop control adopted by the system can meet the requirements under different working conditions.","PeriodicalId":186085,"journal":{"name":"2020 24th International Conference Electronics","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127010605","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}

Such generators are used as sources of short (tenths of a nanosecond) pulses. The latter are the basis for: measuring instruments, impact excitation of ultra-wideband antennas of radar sensors, radar of underground sounding and other purposes. To enable a comprehensive analysis of elements the system of differential algebraic equations is solved. The Equations are written for Kirchhoff's laws, describing the “behavior” of currents and voltages of discrete circuit elements, and the parasitic inductors and capacitors also. This is caused by strong influence of parasitic components on transients in the circuit, operating in the time range of less than a nanosecond, which is equivalent to the gigahertz frequencies and higher. The obtained solutions made it possible to reveal the influence of the nominal values of the generator circuit elements on its output resistance. Adjusting the output resistance of the generator to a value close to the characteristic resistance of the line, through which the pulses of the generator are transmitted to the load, maximize the transmission of power to the load and eliminate masking of the useful signal by pulses of re-reflections in the line.","PeriodicalId":186085,"journal":{"name":"2020 24th International Conference Electronics","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131683472","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}

During the harvesting, crushing rate could be affected by factors like crop status, operation parameters, working condition and so on. Aiming at identifying the influencing factors and minimizing the crushing rate effectively, a mathematical model of the crushing rate was established through four-factor and three-level field experiments in this paper. The optimum operation parameters of combine harvester were identified through range and variance analysis. The field experiment results showed that the effect level of the four factors was: moisture content > threshing cylinder rotation speed > operation speed > concave clearance. Through simulating the optimization equation, the best parameter combination under the field experiment condition was obtained: 6 km/h - operation speed, 900 r/min - threshing cylinder rotation speed, 15 mm - concave clearance, 14.4 % - moisture content and 0.72 % - crushing rate as the minimum value.","PeriodicalId":186085,"journal":{"name":"2020 24th International Conference Electronics","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132876651","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}
