Abstract: Reuse of design knowledge may play an important role during the variant design and improvement of complex mechanical products. In the paper, a design knowledge reuse model and a knowledge-reuse-based process model with helical evolution were proposed. Effective management and timely updating technology of design knowledge was also analyzed and explored, and a knowledge-reuse-based computer design system was developed. Moreover, taking a slipform paver as an example, variant design and improving steps of complex mechanical products was intrduced.

Abstract: The Application of honeycomb structure was studied for the large-scaled structures in the paper. Stress and strain distribution of different nephogram structure is gained by the finite element method (FEM), the simulation results are discussed. Based on above-mentioned analysis, the evaluation of distortion is accomplished. The research provides a useful reference for the design of large-scale structure; it has had a certain project practical value and theoretical research value academically.
