Design and Optimizated Simulation of Bicycle Frame Structure

The frame is not only the main body of the bicycle but also the bearing part of the bicycle. It bears the gravity of people and the weights of the bicycle. It must have enough reliability, durability, and lightness. According to the working conditions of the frame, the strength is checked from static strength and fatigue strength, and the length of each member of the bicycle frame and the angle between them are designed. The model is created by using PRO/E three-dimensional design software. The established three-dimensional model is imported into ANSYS finite element software, and then the static and modal simulation of the frame structure is established. Finally, the optimization of the frame is completed according to the analysis results.
