SHOCK ANALYSIS OF STRUCTURAL NETWORKS.
Abstract
Two separate reports are included. The first presents a new approach for developing optimum finite element models of structures based on the concept of mechanical impedance. It is shown that individual segments of the structure may be optimized separately so that the impedance at points of connection is accurate. An example is given to demonstrate the accuracy of steady-state and transient response of a system of beams and springs in which the improved models are used. The second report describes representation of bar and beam segments by models having equally spaced mass elements. Errors in natural frequencies, modal factors, and mechanical mobility introduced through the use of finite models are discussed.
