Abstract:

Comparisons are made between theoretical and measured resonant frequencies for three representative hydrofoil configurations Inverted Pi, Vee and Inverted Tee, with variable end conditions and depth of submergence in water. Theoretical calculations were based on influence coefficients, accounting for the apparent mass effect of the water. Agreement on frequencies through the first six to eight modes of vibration for all configurations is generally excellent, being well within 10 in most instances and in no case greater than 18. 1. Agreement on mode shapes is also generally good. Author
