摘要

With the purpose of researching how the parameters such as style, pitch and rod length of the attach member impact the overall crane, the variation of the strength and stiffness in attach member. The theory of nonlinear big displacement is adopted to model the overall crane. And the model was considered in several working conditions, then the trends of the stress, axial force and the displacement are shown by Graphics and data. From above, a better style of the attach member can be chosen and this method which is shortening the distance between tower centerline and outer wall lengthening the rod of attach member would be helpful to the attach member program in engineering.
