| Abstract: | Static and dynamic tests have been done on excavator's attachments in order to see strength of hydraulic excavator.According to features of stress distribution over the box section under an outer force we have laid out 14 test points over positions where stress is concentrated such as the lift arm,bucket arm and etc.We have collected static-strain time-domain signals at the test points for bucket teeth digging resistance,as well as dynamic-strain time-domain signals from no-load descent impact,and those fro... |
