| 1 | Research on Startup Reliability of Ultrasonic Motors显示文摘作为一种在航空航天和武器系统有着广泛用途的新型微电机,超声电机的启动可靠性影响了其进一步的推广应用。该文通过理论分析将影响电机可靠启动的因素定位为定、转子摩擦界面阻力的增加以及定子的非线性振动,其中摩擦界面阻力增加包括摩擦材料嵌入定子槽中以及摩擦材料与定子的粘接。结合仿真分析和实验研究,证明超声电机定子振动的非线性是影响电机可靠启动的根本原因,越靠近共振频率非线性越严重,而定、转子接触界面的粘接以及摩擦材料嵌入定子齿使定子谐振频率升高,也就使原有工作频率更接近共振频率,从而导致电机定频启动困难。最后提出利用定子振动的非线性,采取降频启动的方法,可有效提高电机启动可靠性,为超声电机的推广应用打下良好基础。 | LI Huafeng DING Qingjun CHEN Chao | 2013 | 中国电机工程学报2013，33，9： | 7 |
| 2 | Rapid drift of the Tethyan Himalaya terrane before two-stage India-Asia collision显示文摘The India-Asia collision is an outstanding smoking gun in the study of continental collision dynamics.How and when the continental collision occurred remains a long-standing controversy.Here we present two new paleomagnetic data sets from rocks deposited on the distal part of the Indian passive margin,which indicate that the Tethyan Himalaya terrane was situated at a paleolatitude of∼19.4°S at∼75 Ma and moved rapidly northward to reach a paleolatitude of∼13.7°N at∼61 Ma.This implies that the Tethyan Himalaya terrane rifted from India after∼75 Ma,generating the North India Sea.We document a new two-stage continental collision,first at∼61 Ma between the Lhasa and Tethyan Himalaya terranes,and subsequently at∼53−48 Ma between the Tethyan Himalaya terrane and India,diachronously closing the North India Sea from west to east.Our scenario matches the history of India-Asia convergence rates and reconciles multiple lines of geologic evidence for the collision. | Jie Yuan Zhenyu Yang Chenglong Deng Wout Krijgsman Xiumian Hu Shihu Li Zhongshan Shen Huafeng Qin Wei An Huaiyu He Lin Ding Zhengtang Guo Rixiang Zhu | 2021 | National Science Review2021，8，7： | 7 |

| 15 | A New Topological Description Method of Kinematic Chain显示文摘This paper presents a novel method for the description of kinematic chains, namely the canonical description of kinematic chains including the synthetic degree-sequences and the canonical adjacency matrices sets of kinematic chains. The most important characteristic of this new description method is its uniqueness. Based on the new principle the isomorphism identification becomes easy and the structures of all kinds of kinematic chains can be stored in computer for the benefits of the realization of automation and intelligence of machine design. | Ding Huafeng Huang Zhen Cao Yi | 2004 | 机械设计与研究2004，20，z1： | 1 |

| 18 | Theory of loop algebra on multi-loop kinematic chains and its application显示文摘Based on the mathematic representation of loops of kinematic chains, this paper proposes the ' ⊕ ' operation of loops and its basic laws and establishes the basic theorem system of the loop algebra of kinematic chains. Then the basis loop set and its determination conditions, and the ways to obtain the crucial perimeter topological graph are presented. Furthermore, the characteristic perimeter topo-logical graph and the characteristic adjacency matrix are also developed. The most important characteristic of this theory is that for a topological graph which is drawn or labeled in any way, both the resulting characteristic perimeter topological graph and the characteristic adjacency matrix obtained through this theory are unique, and each has one-to-one correspondence with its kinematic chain. This character-istic dramatically simplifies the isomorphism identification and establishes a theoretical basis for the numeralization of topological graphs, and paves the way for numeralization and computerization of the structural synthesis and mechanism design further. Finally, this paper also proposes a concise isomorphism identifica-tion method of kinematic chains based on the concept of characteristic adjacency matrix. | HUANG Zhen DING HuaFeng | 2007 | Science China(Technological Sciences)2007，50，4： | 1 |
