Abstract This paper presents a systematic rapid creative design framework for complex mechanisms to support creative conceptual design schemes’ generation and 3D virtual simulation. In conceptual design stage, a rule-based creative conceptual design system is constructed to expand conceptual design solution space through operating design rules related to functional requirements of design problems with graphic carriers. Compared with FBS models or catalogue-based matching approaches, the rule-based system can dig out more innovative conceptual design schemes including generalized mechanisms. Then a great number of conceptual design schemes generated in conceptual design are represented with symbolic schemes and identified into constituent basic mechanisms and their connections. To the constituent basic mechanisms, the object-oriented (OO) technology is applied to set up their 3D virtual solid models with encapsulated key feature parameters, which can be automatically modified by system’s database with the aid of the new defined classes. According to the OO solid models of constituent basic mechanisms and their connections, a 3D space layout algorithm considering the connections among the solid models is developed to determine the position of each constituent solid basic mechanism. Finally, an object-oriented based kinematic analysis method is pro-posed to carry out automatic kinematic analysis of the complex mechanisms related to the symbolic schemes. By means of the virtual-assembly approach and the kinematic data, all constituent components in the complex mechanisms are put onto the proper positions as they are assembled manually. In this way, the systematic design processes for complex mechanisms from creative conceptual design schemes’ generation, to 3D virtual solid design, layout de-sign, kinematic analysis, and virtual assembly and simulation are realized automatically. Based on the framework presented in this paper, rapid generating and evaluating innovative, excellent-performance schemes of complex mechanisms in 3D virtual prototype form are possible.

This paper presents a design approach for the conceptual design of a novel 16-speed bicycle drive hub. First, a distributed-flow type planetary gear train, which consists of two parallel- connected transmission units and one differential unit, for the power transmission mechanism of a bicycle drive hub is proposed. Based on the kinematic analysis of the presented gear mechanism, a feasible clutching sequence is synthesized to provide 16 forward speeds. Then, the numbers of teeth of all gears are determined according to the desired velocity ratio of each speed. As a result, a schematic diagram of the embodiment of the proposed 16-speed drive hub is presented.

The Given

The parting line design for vehicle door is an indispensable step at the phase of auto-body conceptual design, and also the premise of door kinematic analysis. Combined the CATIA CAA platform characteristics with the hinge layout features, we propose an intelligent and semiautomatic algorithm for parting line design and build a layout and checking module based on CATIA software platform. The present method, which originates from an introduced procedure of hinge layout, could define two envelop curves called K-Lines to judge if the given parting line is reasonable. It calculates the minimum clearance size between doors and surrounding parts on each section by using a transform with some settled parameters. In reverse, when the sizes are set to 0s, a serial of extreme start and end points help the engineer to design two new parting lines. An example is carried out with our module and the position relationship between K-lines and parting line are analyzed. The results show that our method has great feasibility and validity to design the parting line and shorten the design periods.
