Development of Random Response analysis Capability for the VAST Finite Element Program - Phase 2

Abstract

This report contains a description of the work done in the second phase of a contract awarded by the Defence Research Establishment Atlantic (DREA) of the Canadian Department of National Defence for the development of an in-house random response analysis capability. A description of additional work to complete the modal random vibration analysis module (RANVBI) is given. The development of a twin module (RANVB2) based on the direct frequency response method is presented. A brief description of the graphics support to the random response analysis programs is also given. Example problems illustrating the operations of RANVBI and RANVB2 are given. The report closes with some comments about the impressive features of the random vibration capabilities of the VAST finite element analysis system and highlights some recommendations that would further enhance the current capabilities.
