Extreme product tests\r\nare realized to prevent failures in design process, but these tests\r\nrealized experimentally result in high costs. Finite element analysis is\r\nan effective tool used for design process. These analyses are used\r\nbefore production of prototype for validation of design according to\r\ncustomer requirement. In result of this, substantial amount of time\r\nand cost is saved. Finite element model is created for geometries that are designed in\r\n3D CAD programs. Different element types as bar, shell and solid,\r\ncan be used for creating mesh model. Cheaper model can be created\r\nby selection of element type, but combination of element type that\r\nwas used in model, number and geometry of element and degrees of\r\nfreedom affects the analysis result. Sliding door system is a good\r\nexample which used these methods for this study. Structural analysis\r\nwas realized for sliding door mechanism by using FE models. As\r\nwell, physical tests that have same boundary conditions with FE\r\nmodels were realized. Comparison study for these element types,\r\nwere done regarding test and analyses results then optimum\r\ncombination was achieved.","references":"[1] S.
