The operation and maintenance system of AČR fleet has a space for improvements, which is sought out by the current analysis and following proposals. All the following proposals are representing part of a complex system solution, which involves current trends of modern NATO armies as is Condition Based Maintenance Plus (CBM+), Health and Usage Monitoring System (HUMS) or Integrated vehicle health management (IVHM) systems. The KBVP Pandur II CZ is the one type of vehicle in the AČR vehicle fleet that has the best potential for the maximum and effective use of the available information. However, it does not currently fully exploit its information potential for the vehicle availability prediction system yet. Naturally, all current fleet vehicles such as Iveco LMV, T-72M4 CZ, TS10, etc., including referential vehicles, especially the Škoda (VW group) vehicles and buses were analyzed by the authors. The aim was to propose and develop a progressive prediction system for the operation and maintenance of the army fleet, which will also allow for a better quality of life cycle management (LCC).","PeriodicalId":107301,"journal":{"name":"2019 International Conference on Military Technologies (ICMT)","volume":"278 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121447279","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 study is needed to monitor the mental state of fighter pilots during training. Knowledge of a pilot’s mental state during training could help to determine their readiness to perform a combat mission. It is generally known that changes in mental state and stress is manifested in electrical activity of the brain. To assess variations in the brain’s electrical activity, it is assumed to use the electroencephalography (EEG) signal. EEG signals were obtained from two fighter pilots. The data was recorded during training missions on a flight simulator. The simulated training mission was composed of three submissions (composed of stressful events and mid events). The non-linear Poincaré plot analysis was used for evaluation of EEG variability during training. The results were presented using the brain electrical activity mapping. The results showed statistically significant differences in EEG variability, when comparing a stressful event with mid event periods. This finding demonstrated the ability of the proposed method to quantify mental load, i.e. the stress of fighter pilots during flight simulator training. The results can help evaluate the stress and readiness of individual fighter pilots.","PeriodicalId":107301,"journal":{"name":"2019 International Conference on Military Technologies (ICMT)","volume":"209 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114267794","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}

Many vehicles are being equipped with independent suspension for its unquestionable advantages over dependent. Still, for medium or heavy trucks, designed for off road conditions, dependent multi-leaf spring is preferred in some cases. Further enhancement of the mobility can be achieved with tandem bogie layout. For the behavioral study of the dynamic motion of the aforementioned vehicles, a great number of the inputs is required. Mainly from the suspension components, since they are in direct contact with the road surface. Some of them can be omitted, but others are crucial for the achievement of adequate value of correlation coefficient between the proposed dynamic model and its experimental validation result. One of those crucial inputs is the behavior of multi-leaf spring under the certain circumstances. The behavior is mainly set by the stiffness characteristic (force-displacement curve) and the phenomenon called hysteresis. If the characteristic is unknown and the only information about the multi-leaf spring are its dimensions and materials, the solution lays within the utilization of FEM. With the results from the simulations, a stiffness characteristic can be constructed. Therefore, the paper is divided into following steps: firstly, the brief introduction along with a state of the art was carried out. Secondly, a simple model was created and hysteresis was observed. Then the leaves were prestressed, in a factory way of assembly, and the force-displacement characteristics were conducted for a various values of coefficient of friction between the leaves. Lastly, the utilized method was summarized and evaluated.","PeriodicalId":107301,"journal":{"name":"2019 International Conference on Military Technologies (ICMT)","volume":"22 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127007517","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}
