中文摘要： 现代工业不断向高速、高温、高压的方向拓展，对重载冲击金属机械易损零部件的强度和韧性提出了更高的要求。因此，如何提高金属机械易损零部件的强韧性提高其服役寿命，成为目前企业的一个重大需求，是一个亟待解决的问题。耦合仿生给我们提供了解决宽幅度可控调整金属机械易损零部件机械性能难题的理论基础，有望帮助我们解决传统单元仿生难以有效解决的问题。在本项目中，我们拟"师法自然"试图模仿动物和植物的结构、形态、功能和行为，运用仿生耦合的理论解决工程仿生所面临的难题，通过研究生物的耦合信息，找出生物耦合信息与金属机械零部件特性的共同点，来建立金属部件性能的仿生耦合模型，最终实现金属机械零部件对各种不同性能的要求。根据仿生耦合理论，对机械部件材料的主要矛盾因素进行仿生耦合研究，找到其中的共性，模仿生物的体态，体貌，实现材料强度和韧性不能共存的突破，通过仿生耦合让材料的性能像生物体一样不断进化、优化。

英文摘要： Modern industries continue to expand to the high-speed, high temperature, high pressure, the direction of a higher demand on the large metal mechanical strength and toughness of the vulnerable parts. Therefore, how to improve the strength and toughness of the metal mechanical wearing parts to improve its service life has become a major demand of the enterprises is an urgent problem.Coupling bionic we provide the theoretical basis to resolve the wide amplitude controlled to adjust the metal mechanical wearing parts mechanical performance problem is expected to help us solve the difficult to effectively solve the problem of the traditional unit bionic. In this project, we intend to "Nature as Teacher," trying to imitate the structure of animals and plants, form, function and behavior, the use of bionic coupling theory to solve the problems faced by the engineering bionics and coupling through the study of biological information, to identify biological coupling information and metal mechanical parts, features common to create a bionic model of the metal parts of the performance of the final metal mechanical parts on a variety of performance requirements. According to the theory of bionic, bionic research, the principal contradiction of the mechanical components material factors, find the common mimic biological bod
