The finite element software ANSYS/LS-DYNA is used to analyze shock resistance test of a bicycle frame. Using Kriging interpolation method, both response surfaces and mathematic models are built. Besides, through nonlinear programming of MATLAB, it is figured out the best specification of the bicycle frame, which fits on the shock resistance test and the nature frequency of a bicycle frame. Take the factors of uniform experimental design as input, and the bicycle frame mass and the first nature frequency as output to build Kriging models of bicycle frame, the front fork distortion and the nature frequency. In order to reduce the mass of bicycle frame and increase the first nature frequency, let the distortion of the front fork to be the constraint in this paper. Using the toolbox of MATLAB nonlinear program, the best combination parameters of bicycle frame are obtained with the different boundaries of distortion.
