Abstract: An elastomeric vibration damper experiencing cyclic loading within a helicopter rotor blade assembly is analysed to better understand its thermal characteristics. Experimental testing shows that elevated temperatures contribute to the degradation of the elastomer and adhesive system, shortening service life. The statistical approach of 'Designed Experimentation' is used to combine numerous design and environmental variables to find maximum temperatures within the damper. Both structural and thermal finite element analyses are used within the designed experiment to determine high temperatures of the damper for each of several trials. The designed experiment then ranks each variable in order of importance in creating high temperatures within the damper.
