Abstract
- A theoretical and experimental study is presented for determining the steady‐state frequency response of laterally excited truncated cones and cylinders in a low to moderate frequency range. The theoretical results are formulated in terms of forward transmission matrices, although relationships are reviewed which allow application of the results for impedance or admittance formulations as well. Expressions for the 4×4 matrices of transmission for coupled bending‐shear displacements are developed by means of the membrane theory of thin shells. The results are then applied to the case of laterally excited shells that support a rigid top mass. Input and transfer coupled impedances are calculated and compared with experimental observations for 30° and 15° cones and a cylinder. Over‐all comparison of the results indicates that the membrane theory provides a reasonable approximation for determining response characteristics, but some definite deficiencies remain unexplained.
