Abstract: Shock isolation parameters for mine blast resistant seating are developed based on a damped harmonic oscillator model. Required seat stroke allowance for different vehicle types and blast impulse levels is provided. Optimal solutions are presented for minimizing acceleration and Dynamic Response Index (DRI), as well as the corresponding acceleration profiles. The DRI limits are shown to be more restrictive than acceleration limits found in the literature.
