Abstract
In many technical applications elastic bodies are coupled through extended contact interfaces by means of bolted joints forming an elastic structure. The housing of an internal combustion engine built up of the crankcase, the oil pan, the cylinder head and various covers can be regarded as a practical example for an elastic mechanical structure. To understand the influence of extended friction contacts on the dynamic behaviour of elastic structures, the forced vibrations of a test structure consisting of two elastic half tubes joint together in two bolted flanges will be analysed. The contact interfaces in the flanges can be considered as dry and extended friction contacts. Since the test structure is loaded with a harmonic external force, relative displacements occur in the contact interfaces. Depending on the normal pressure distribution and magnitude as well as on the contact surface characteristics these relative displacements lead to microslip effects affecting the dynamic behaviour of the test structure.A calculation method accounting for these effects is presented and experimentally validated by comparing measured and calculated frequency response functions (FRF) of the test structure.
