| Abstract: | From the point of view of the stress component combination this paper presents the calculation method and formula for the equivalent principal stress on a test point in two-dimensional stress field when the structure of construction machinery and eiuipment is sub-jected to the actions of its weight and loading in structural strength experiment. It is of sig-nificance for the test data-processing and saf-ety judgement of the structure of construction machinery and equipment. |
