Sažetak

The paper presents how a V10 engine block made of light alloys of aluminium is assembled with the cylinders casings made of grey cast iron alloys. The solution used in this case is shrink-fit technology. To obtain such an assembly it is required to study the phenomenon of thermal expansion of the bodies with complex geometries such as an engine block. The only viable solution to study the thermal phenomena for shrink-fit assembling is to use finite element methods for simulating. Five different cases are presented for the V10 engine block heating and for the optimal case, in which a clamping device is used for its positioning, the thermal expansions are determined. The final result is a mathematical relation which represents the dependences between the thermal expansions of the V10 engine block and temperatures.
