车载卷轴式遮雨器的设计与研究

为方便阴雨天气时乘车人进出车辆,同时有效避免车内设施在开关车门期间被淋湿,设计了一款车载卷轴式遮雨器。本设计采用扇形卷轴及骨架支撑结构,通过蓄电池为装置中的电磁铁供电,同时结合雨量传感器对电磁铁进行开关控制。用户在打开车门时对装置施加初始拉力,安装在车顶及车门间的遮雨布通过电磁铁间吸力带动展开,在车门及车顶间隙形成扇形遮雨区域,为用户进一步打开随身携带的雨伞提供执行空间的同时,有效规避车辆内饰被淋湿。通过多方面的可行性分析,该设计能够满足安全使用的条件并达到预期目的。     

按图索“路”——道道通导航使用测试

古时寻找宝藏的人总要手持一个羊皮卷轴,按典寻宝。而今无论你是驱车远行,欣赏名山大川,还是近距离观光,浏览沿途风景;无论你是行驶在一个陌生的城市,亦或是穿梭在熟悉的空间,有一张索引图在手,心中总会踏实很多。     

Structural Multi-objective Probabilistic Design for Six Sigma

Uncertainties in engineering design may lead to low reliable solutions that also exhibit high sensitivity to uncontrollable variations. In addition, there often exist several conflicting objectives and constraints in various design environments. In order to obtain solutions that are not only "multi-objectively" optimal, but also reliable and robust, a probabilistic optimization method was presented by integrating six sigma philosophy and multi-objective genetic algorithm. With this method, multi-objective genetic algorithm was adopted to obtain the global Pareto solutions, and six sigma method was used to improve the reliability and robustness of those optimal solutions. Two engineering design problems were provided as examples to illustrate the proposed method.
