Thermal Expansion Analysis of the Complex Body Assemblies

Abstract:

This paper presents a method of finite element modelling used for thermal expansion analysis of the complex body assemblies. In this research, the assembly of complex body consists of single cylinder air cooling engine block and fixtures necessary for machining and assembling with cylinder casing. The assembly is loaded with an uniform distributed thermal field and the thermal expansion for internal sections of engine block is determined. The minimum section is used for assembling between engine block and cylinder casing by shrink fit technology. The paper also presents a comparison between results obtained using two different methods: linear thermal expansion and finite element method. The final results are implemented in a software tool, named GENgine, developed by the authors and used for digital manufacturing of engine block.
