Research on Simulation Loading System With Magnetic Particle Brake Controlled by Single Chip Microcomputer (2nd half)——Simulation Test and Evaluation of Loading System

The loading system developed can be used either indoor to simulate a torsional load or to duplicate an actual drawbar load in the field. Utilizing the system, sinusoidal load, saw-tooth load, load spectrum and actual load obtained when a tractor was being operated in the field were simulated. It is shown by χ² examination that the distribution of all simulated load curves accords with that of their sample curves under level 0. 05.
