FATIGUE ANALYSIS AND WARNING SYSTEM

摘要

In the field of large construction and mining equipment, significant frame stresses considerably shorten the expected operating life of a machine. This invention provides indications of significant frame stresses on machines having a ground engaging portion, a frame connected to the ground engaging portion, and a plurality of pressure sensing devices. Each of the pressure sensing devices are adapted to produce pressure signals indicative of loads imparted on the frame. The pressure signals are processed to produce frame stress data.
