摘要： A method and an apparatus for absorbing the energy of shock impact loads are disclosed. In accordance with the method, an elastomeric member is axially advanced along a friction surface and into a confined condition upon impact loading to simultaneously provide friction and resilient deformation reaction forces having a substantially constant additive total. The elastomeric member is preloaded in an axial direction and the friction interface developed is of controlled lubricity to assure efficient energy absorption and uniform reaction forces independent of temperature and impact velocity. If velocity sensitivity is desired, the friction surface and preload can be modified to provide direct velocity sensitivity wherein the reaction force increases with the velocity of the impact. The apparatus includes an impact receiving piston axially disposed within a casing and arranged to load the elastomeric member. The casing includes a restricted first portion which provides an elastomer engaging friction surface and an enlarged second portion into which the elastomeric member is advanced and resiliently deformed.
