摘　　要：在机械设计中,引入定性仿真方法来弥补创新过程中的未知性和不确定性,采用创新的QS-CURVE(定性仿真曲线)来形象化地描述各机械基础单元结构,即"实现功能的最小单元机构"(BMU)的运动关系,并用定性仿真帮助设计者对原机械的BMU进行改造从而得出创新的功能,用定性变量来描述运动状态可以避开具体设计中的细节,使设计者更好地掌握创新机械的运动性能,从而降低了设计的复杂性。最后本文通过对摇杆机构的改造对上述方法的合理性、正确性加以验证。In mechanical design, simulation is introduced to compensate the unknown feature and uncertainty in the innovation process, the innovative QS-CURVE is used to visually describe the movement relationship of the basic mechanical units （BMU）, i.e.＂the minimum mechanical unit to achieve function＂, and the qualitative simulation is used to help designers carry out reform of BMU so as to get Innovative function, also the qualitative variables are used to describe the change of movement state, so that the specific details of the design can be avoided, making the designers being able to grasp the movement performance of the innovative machinery, and reducing the complexity of the design. Finally the rationality, correctness of the above-mentioned method are verified through the reformation of rocker mechanism.
