【Abstract】 In order to know well the fatigue condition of a new sleeve type rubber vibration isolator for Jin Sui Model 4SW series potato digger, the tests both in field and laboratory conditions were conducted, the static rigidities of rubber vibration isolator under non fatigue testing and fatigue testing in field and laboratory conditions were measured; and the value of the static rigidity was gained by fitting technique. The testing and measuring results showed that the rubber vibration isolator satisfied the requirement for production practice and designed service life as well as its usage. On the other hand, a value of static rigidity loss was advanced as a measuring criterion of fatigue failure and it proved feasible.更多还原
