Simulation Study Of Bicycle Innovative Design And Its Implementation

Innovation is considered as one of the most important and challenging process in developing new products. Research on innovation of products and technology has been more and more concerned in many fields home and abroad. In this paper, bicycle innovative design is studied and its simulation software is programmed in order to cultivate the undergraduate students?creative ability and help them to carry on further innovative design. Many fields are involved in this paper, such as innovative thinking science, innovative design method, bicycle design, computer simulation, computer-assisted instruction, etc. At the beginning of this paper, the relative theory of innovative thinking and the theoretical methods of creative design are summarized based on many overseas and domestic literatures. And the main innovative forms of modem bicycle are analyzed. The above introduced lays the theory foundations of bicycle innovative design. And then, bicycle innovative design process is introduced by examples of bicycle frame structure and transmission plan design. According to the principle of bionics and ergonomics, creative exploitation of new bicycle frame is carried out. The proposed human-bicycle modal during normal cycling is established on a five-bar linkage and explicit expressions for the kinematics are derived with mechanical property analysis. On the other hand, the finite element analysis software is used in stress calculation of frame structure to test fasibility of plan design. Further more, new type transmission system of bicycle is refereed, where mechanical performance is compared with each other. The idea is brought forward that research on innovative plan design in bicycle transmission system should begin with the analysis of inherence in transmission-mechanisms and relativity between them. In the end, bicycle innovative design system is integrated by the Authorware multimedia authoring software. Five main modules are established. They are development history of innovative design, knowledge of innovative methods, knowledge of plan design in transmission system, dynamic simulation of bicycle frame structure and animation effect demonstration. The last two are developed in depth with VC~ language. Friend man-machine interactive interface is programmed. Three-dimensional solid modeling with various light effects is completed and its animation display is shown. As a result, the prototype software of bicycle innovation design is worked out which is provided the undergraduate students with study and practice.
