Dynamic Failure Analysis of Earthmoving Equipment * 690356

This paper describes techniques for dynamic evaluation of complex mechanical systems, particularly construction equipment. By coupling experimental and analytical techniques, a thorough understanding of system performance can be obtained, and improved predictions of dynamic failures can be made. In particular, the ability to obtain reliable predictions of system stress and/or vibration response to adverse loading conditions is presented.
It is not necessary or advisable to restrict the testing of earthmoving and agricultural equipment to static loading conditions only. Dynamic studies, using combined automatic transfer function analysis (TFA) equipment and related computer capabilities, are practical and beneficial. The object of this paper is to point out advantages of dynamic investigations and to present another tool for construction and agricultural machinery engineers in their continuing endeavor to improve their products.
