About the Analysis of Post-Impact Oscillator Phenomena Which are Produced in Protective Structures Subjected to Shock Loadings, Using Mechanical Event Simulation
Journal Title: Romanian Journal of Acoustics and Vibration - Year 2010, Vol 7, Issue 2
Abstract
The article presents some aspects of the analysis oscillatory phenomena occurring after applying a shock loading to a protective structure using response simulation of the structure after impact. Protective structures considered are the ROPS/FOPS structures and mechanical shock is simulated in accordance with the recommendations of reference documentation. In the first part of the article are summarized the main definitions and notations used in connection with structures ROPS/FOPS and the benefits of numerical simulation of the behavior of mechanical systems. Next, are presented the main aspects of modeling that have a decisive influence on the accuracy of the results which are obtained from post-impact analysis: choosing the right type of finite elements, choosing of the correct material models, setting control scheme and convergence criteria valid, during the behavior simulation of the target structure. All these elements are applied in a case study and final part of the article is dedicated to present some recommendations and conclusions.
