The most significant and the most used methods suitable for this vibrodiagnostic field have been selected, namely support vector machine, k-nearest neighbor, Mahalanobis-Taguchi system and principal component analysis for reduction of a dimensionality of a features space. All the methods have been implemented in MATLAB and their performance has been analyzed using same input datasets. As the input for all the aforementioned methods, data from bearing shortened life-cycle test, done by Bearing Data Center at Case Western Reserve University, have been used. Intentionally, computationally intensive pre-processing procedures have been excluded from the computational chain, as only time domain features have been used for the classification process. Resulting from this study, a classification error rate, an execution time, an implementation difficulty and a robustness of the algorithm strongly differ among all the methods while using the same input data and the same number and type of the input extracted features.","PeriodicalId":166043,"journal":{"name":"2020 19th International Conference on Mechatronics - Mechatronika (ME)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115118870","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}

Therefore, experimental studies still have an irreplaceable role in design process of the mounting system, especially because it is a component involving rubber-like materials with many sorts of difficulties for computational simulation due to its nonlinear complex static and dynamic characteristics. But physical prototyping and testing is highly time-consuming and expensive process, so using of simplifying and accelerating testing methods is highly required. This article describes influence of two cases of the powertrain mounting method on vibration of both sides of powertrain mounting system (in front of the mount – the engine side (active side), and behind the mount – the chassis side (passive side)), whereas first case is powertrain assembly in a test rig (powertrain dynamometer) and second one is powertrain mounted in a car (chassis dynamometer). The experiment was carried out on a small passenger car powertrain with three-cylinder sparkignition engine.","PeriodicalId":166043,"journal":{"name":"2020 19th International Conference on Mechatronics - Mechatronika (ME)","volume":"250 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123259599","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}

Topology optimization can lead to a reduction in energy consumption thanks to the higher efficiency of optimized electrical machines. The topology optimization is based on the normalized Gaussian network (NGnet) within this paper. The dependency of the NGnet on the distribution of Gaussian functions is analysed in detail. The evaluation algorithm of a single individual is developed. The algorithm manages communication between Ansys Maxwell and software tool SyMSpace. Furthermore, the algorithm leads to a reduction in computational time due to the preselection of unfeasible geometries. The latter is necessary due to a time-consuming transient analysis considering the machine’s start-up. The topology optimization of LSSynRM based on the NGnet is performed and the results are discussed. One selected optimized design is analysed in detail. The main contribution is the creation of the methodology for the topology optimization of LSSynRM based on the NGnet extended with the evaluation algorithm, which can be used for further improvement of line-start machines.","PeriodicalId":166043,"journal":{"name":"2020 19th International Conference on Mechatronics - Mechatronika (ME)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122365766","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}

Unfortunately, single cylinder engines might not be of the same “generation” as the engines on which investigations are planned. Therefore the need to modify available and current “generation” multi-cylinder engines to single cylinder operation is a task that some engine researchers might require. Detailed literature of how this modification is done is lacking. Therefore this paper details the modification carried out on a four cylinder inline Peugeot Hdi common rail diesel engine to be operated as a single cylinder. This single cylinder engine was required for the in-cylinder heat transfer research being conducted on a pressurized motored setup. The mechanical aspects of the modification as well as the balancing weights determination are explained. Finally, but most importantly, the accelerometer measurements obtained from three piezoelectric accelerometers on the front and rear of the engine (and in two orientations, i.e. along the cylinder axis and perpendicular to it) are presented. These measurements were used to trim the balancing weights.","PeriodicalId":166043,"journal":{"name":"2020 19th International Conference on Mechatronics - Mechatronika (ME)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128898525","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}
