【Abstract】 Based on the developed mathematical model for three kinds of hydraulic loading system, the dynamical characteristics of three kinds of hydraulic loading system are researched theoretically. It is proposed in this paper that the following characteristics of a loading system can be evaluated numerically by the dynamical stiffness of actionpoints of grinding wheel. A lot of experiments are carried out and the results show that the theoretical analysis is correct.更多还原
