Research in Green Modularity Design Methodology

Green design and manufacturing is a proactive approach to minimize wastes during a product＇s design stage, thus preventing future environmental impacts. Current modular design method mainly focuses on product functional and manufacturing issues. In this paper, a theoretical scheme of multi-objective modularity analysis for discrete electromechanical product design was proposed. Product physical architecture was represented by a fuzzy graph, where fuzzy relationships contain environmental objectives and influence module formulation. Finally the optimal product modules combining all objectives can be searched by clustering algorithm.     

基于刚柔耦合的装载机工作装置性能仿真分析

为准确方便地分析装载机工作装置性能设计的好坏,在多体动力学软件ADAMS中建立了装载机工作装置的刚柔耦合仿真模型和性能分析所需要的测量函数。分别对其平移性、自动放平性、连杆机构的动力性、举升机构的举升性、卸料性以及传动性进行了仿真分析,对机构的性能优劣进行了判断。仿真结果与实际工作情况基本一致,建模及分析方法对其他类似机构的仿真研究有参考意义。
