General Aviation Airplane Structural Crashworthiness User's Manual - VolumeⅡInput-Output Techniques and Applications

摘要

Program KRASH has several features which can be used effectively to evaluate crashworthiness capability of vehicles during the initial stages of a design. Conceptually the program is designed to define the general behavior of structure and to provide data which can be utilized to assess chances of occupant survivability during a severe crash environment. While KRASH currently contains one measure of injury potential (Dynamic Response Index, DRI), the data obtained from KRASH are more useful as input to more complex seat-occupant-restraint system models. Since the program utilizes simplified and approximate representations of structure, it best can be described as a preliminary design tool.
