Stress Testing of Clark Model 45B Tractor Shovel

The question of what constitutes a realistic stress testing program, and how it is performed and then applied to earthmoving vehicles, is of prime interest to the design engineer. A general understanding of how the various tests are performed and their relationship to the total picture will enable the designer to work with testing personnel to develop vehicles that will have a minimum of structural problems in the field. Emphasis will be put on three basic stress testing procedures, namely static, pseudodynamic, and duty cycle field tests.
