Development and manufacture of tester on the dynamic parameters for digging machine

It is an important basic theoretical study for the relationship between the dig ging machine's dynamic mechanical parameters (torque and feed resistance) and it s influencing factors(drill rotation speed,drill feed speed,soil composition,soi l hardness,soil humidity) and working parts, structural parameters.The tester is the necessary condition for the study,therefore the authors developed the new tester of the digging machine's dynamic mechanical parameters for testing data. The tester can change the values of influencing factors according to experiment demands.The authors logged the data of dynamic mechanical parameters in the whol e process of digging exercise through the electromotive method by precision sens ors and computer data logger system.This bring forth a new idea in the field of digging machine related to afforestation machinery.It proved that the tester was very stable and reliable.
