Development of Additional Federal Outdoor Impact Laboratory (FOIL) Facilities. Volume 2. Validation of the FOIL Pendulum Upgrade

摘要

The report documents the design, development and validation of an upgraded pendulum for the Federal Outdoor Impact Laboratory. The pendulum, which is designed to simulate the low-speed impact of a small automobile into breakaway luminaire and sign supports, has been upgraded with an 1800-lb (817kg) mass, a new crushable nose design, special features to reduce pendulum harmonic ringing after impact, a new sweeper plate design, and provision for mounting on board accelerometers. Additional facility modifications developed as a part of this upgrade include a removable rigid foundation for mounting luminaire and sign supports and a new speed trap system. This is Volume II of a two-volume final report. Volume I is entitled 'Preliminary Design Study for Upgrading FOIL to Test with Heavier Vehicles.'
