Abstract: | Tanks and pipes vibrating in flexure and filled with various materials have been a problem in power plants, factories, airplanes and tankers. The present experimental investigation was carried out on a pipe vibrating in flexure and filled with various materials, both liquid and solid. The tests showed that, in general, filling a pipe in flexure with any material, liquid or solid, increases its damping characteristics. An increase in the kinematic viscosity of the filling liquid, or a decrease in the size of the particles of the filling solid, will result in a corresponding increase in the equivalent damping factor of the system. |
