| 摘要： | This report addresses a new design concept for a Truck Mounted Attenuator used for work zone safety, which was conceived to redesign the TMA to achieve a cost-effective and practical solution to current TMA problems. These problems are related to truck dump bed usage, extension length behind the truck, and electrical connections subject to corrosion. In Phase I, a new TMA concept was proposed, which was based on the use of hydraulic shock absorbers (HSAs) to reduce the size and maintainability requirements as compared with existing systems, yet still meet NCHRP performance requirements. Phase II of this project focused on the initial development of this HAS system, which consists of two large hydraulic shock absorber cylinders fixed to the truck chassis on one end, extending rearward to an impact strike plate on the other end, and supported laterally by utilizing the dump truck body for support and stiffening. / NOTE: Final rept. on Phase 2. / Supplementary Notes: Sponsored by Federal Highway Administration, Trenton, NJ.
