Hydraulic Excavator Bucket Teeth Load-Time Courses Measurement
Based on the bucket teeth load-time courses calculation model under bucket digging condition, the stresses on the hydraulic cylinder piston rods of boom and bucket and the real-time length of bucket hydraulic cylinder were set as measured variables, and a measuring method of the bucket teeth load-time courses was developed which had the advantages of less measuring points, simplified measurement process and low cost. The bucket teeth load-time courses were calculated by inputting the measuring data into the self-developed Constructing Hydraulic Excavators Load Spectrum software, and its characteristics of each digging step in one excavation cycle at digging macadam were analyzed. Then, using rain-flow counting module in FE-SAFE software, the statistical graphs of bucket teeth load-time courses were acquired which could provide the basis for hydraulic excavator reliability design and fatigue life prediction.
