1 EQUIVALENT STATIC LOADS FOR RANDOM VIBRATION Revision N By Tom Irvine Email: October 4, 2012 ________________________________________ ________________________________________ _____________ The following approach in the main text is intended primarily for single-degree-of-freedom systems. Some consideration is also given for multi-degree-of-freedom systems. Introduction A particular engineering design problem is to determine the EQUIVALENT STATIC load for equipment subjected to base excitation RANDOM VIBRATION . The goal is to determine peak response values. The resulting peak values may be used in a quasi- STATIC analysis, or perhaps in a fatigue calculation.

2 11. Transmitted force from the base to the component in each of three axes 12. Bending moment at the base interface about each of three axes 13. The manner in which the equivalent static loads and moments will be applied to the component, such as point load, body load, distributed load, etc. 14. Dynamic stress and strain at critical locations ...
