20.500.12556/RUL-127856 Tolerančna analiza reže polnilnega sistema v avtomobilu Tolerance analysis of the car charging system gap V magistrski nalogi je obravnavana širina reže med polnilnim sistemom in ohišjem avtomobila. Za namen tolerančne analize je bil razvit tolerančni sklad na sestavu, ki zajema ključne dimenzije in njihove tolerance, ki vplivajo na končno širino reže. Razvita so bila namenska programska orodja za izvedbo tolerančne analize po metodi najneugodnejšega stanja, po metodi korena vsote kvadratov in po modificirani metodi korena vsote kvadratov. Izračunane vrednosti širine reže so bile primerjane z vrednostmi, ki so bile izmerjene na koordinatnem merilnem stroju. Za namen kakovostnih meritev je bila izvedena analiza merilnega sistema. V nalogi je bilo ugotovljeno, da so po vseh metodah izračunane vrednosti tolerančnega razpona širine reže večje od izmerjenih vrednosti in njihovem raztrosu na sedmih sestavih, vgrajenih v nominalni vgradni model. This Master's thesis deals with the problem of the size of the gap between the charging system and surrounding car area. For the purposes of the Tolerance Analysis, we researched and built the Tolerance Stack on the charging system, which includes the main dimensions of different parts of the assembly, and their tolerances. The programme softwares for the Tolerance Analysis, based on the Worst-Case Method, the Root-Sum-Square Method and the Modified-Root-Sum-Square Method, were developed. Afterwards, the calculated values were compared to the measured values, which were previously collected by the Coordinate Measuring Machine. Lastly, the Measurement System Analysis was performed, exclusively for the quality and accurate measurement data purposes. At the end, the research data concluded, that all of the Tolerance Range data (calculated according to the three Methods) was much higher than the data, collected by Coordinate Measuring Machine. tolerančno skladanje kakovost v avtomobilski industriji sestav tolerančna analiza Metoda najneugodnejšega stanja Metoda korena vsote kvadratov Modificirana metoda korena vsote kvadratov analiza merilnega sistema tolerance stacking quality in automotive industry assembly tolerance analysis Worst-case method Root-sum-square method Modified root-sum-square method measurement system analysis true false false [T.
