Abstract: This document describes the use of Abaqus/CAE, Abaqus/Standard, True-Load, and Verity weld analysis in fe-safe software to evaluate the durability of a front-end loader linkage. Dynamic field loading for FEA of construction equipment is not always easily replicated by traditional linear static loading methods. Wolf Star Technologies True-Load software along with unit load FEA in Abaqus was used to determine time history loads for a field operation with dynamic loading that resulted in fatigue failures of the linkage. The time history loading was then used in fe-safe to compare the durability of design alternatives and determine a design that met the simulation criteria. The methodology greatly improved the confidence of the design developed through simulation because the field loading was accurately reproduced.
