A simulation-based method for assessment of HSC crew vibration and shock exposure is presented. The simulation scheme includes three modules: Craft response module, Seat response module and Human exposure evaluation module. The first module computes the craft acceleration in the time-domain by a non-linear strip method and delivers input to the second module, where a crew seat model determines the human acceleration exposure time history. The crew's acceleration exposure is assessed in the third module, which includes a strategy to describe the operational profile. The human vibration exposure is evaluated using international standards (ISO 2631-1, ISO 2631-5). In addition, statistical extreme value analyses are used to evaluate the human exposure to shock. The potential to reduce the vibration and shock level is discussed and exemplified using the simulation-based evaluation method to analyse how different seat designs and running attitudes influence the crew vibration exposure.
