Abstract:To support the development of a proposed rule [1], a fullscale
dynamic test and two full-scale quasi-static tests have
been performed on the posts of a state-of-the-art (SOA) end
frame. These tests were designed to evaluate the dynamic and
quasi-static methods for demonstrating energy absorption of
the collision and corner posts. The tests focused on the
collision and corner posts individually because of their critical
positions in protecting the operator and passengers in a
collision where only the superstructure, not the underframe, is
loaded. There are many examples of collisions where only the
superstructure is loaded.
