12 the first mode does not match the value in the operation of the frequency series satok trigger. Can be concluded that the frequency of oscillation of the set trigger satok? Does not result in damage to the great hydraulic hoses? Considering the damage that occurs under conditions of shaking a set trigger satok. Found that high stress values are located on the bend of the great hydraulic hoses. There is a maximum value, the order has a value of 128 pipes 28 MPa, but when the planned repair history evidence analysis found that the greater the hydraulic hoses, custom. In front of the doctor, boil, steam With a history of corruption, rather than another area to analyze and predict the duration that the hydraulic hoses great damages due to fatigue of the material. It found that the service life of the hydraulic hoses, greater longevity, minimum 3 years in a low position hydraulic hoses 10 grades, which is a pipe that receives the maximum stress in the area of the great hydraulic hoses. Study on predicting hydraulic hose duration greater damage due to fatigue. Maintenance plans, to prevent the damage that will occur during the work of the great hydraulic hoses and studies can also be used as a basis to improve the operating conditions of the hydraulic pipe series great.
