Abstract
Warping deformation along the length is one deformation of the thin-walled C-section composite beam (TC2B). Preloading induced changes in the warping deformation should be considered in the tolerance simulation. The paper presents a tolerance simulation for the TC2B assembling under the preloading. Based on numerical model of TC2B and small displacement torsor model, the preloading-modified probability distribution of the warping deviation is obtained. The assembly of the downscaled wingbox illustrates the effect of preloading on the assembling of the TC2B. The results have shown that tolerance simulation with the modified probability distribution is more accurate than the initial normal distribution.
