| 摘要： | Traditional North American light rail vehicle (LRV) designs have relied on the vehicle's overall static strength to protect occupants in a collision. Although this design approach can be effective in limiting penetration from end collisions, it may lead to heavier vehicle designs and does not assure controlled energy dissipation behaviors that result in crash safety improvements. More modern LRV design methodologies incorporate crash energy management (CEM) strategies. The CEM approach specifies a crash response that absorbs impact energy and smoothly decelerates the vehicle and its occupants with controlled deformation that protects the occupied volume. |
