评述了超高强度钢、高强度A1合金和Ti合金表面完整性抗疲劳应用技术的研究和发展。高强度合金疲劳性能对应力集中敏感,不适当的加工工艺和切削热等造成的表面损伤和髙拉应力使其疲劳和应力腐蚀性能损失殆尽。先进的表面完整性加工尤其是表面改性可显著提高疲劳性能,如激光冲击使7475-T761拉-拉疲劳寿命提高约89%,7075-T6裂纹扩展速率降低到原来的1/1500;超声喷丸使超高强度钢低周疲劳强度提高约50%,Ti7A14Mo合金髙周疲劳强度提高约15%;表面超硬化可使Vasco X-2M齿轮钢接触疲劳寿命提高30~35倍等。

An assembly design system is an important part of computer-aided design systems, which are important tools for realizing product concept design. The traditional assembly design system does not record the connection information of production on the engineering layer; consequently, the upstream design idea cannot be fully used in the downstream design. An assembly design model based on the relationship of engineering connection is presented. In this model, all nodes are divided into two categories: The component and the connection. Moreover, the product is constructed on the basis of the connection relationship of the components. The model is an And/Or graph and has the ability to record all assembly schemes. This model records only the connection information that has engineering application value in the product design. In addition, this model can significantly reduce the number of combinations, and is very favorable for the assembly sequence planning in the downstream. The system contains a connection knowledge system that can be mapped to the connection node, and the connection knowledge obtained in practice can be returned to the knowledge system. Finally, VC++6.0 is used to develop a prototype system called Connect-based Assembly Planning (CAP). The relationship between the CAP system and the commercial assembly design system is also established.

本文回溯了19 世纪末以来西方关于设计科学的争论,探讨在前工业设计时期、工业设计时期和后工业设计时期中关于设计认知和理念的变化,特别是它们在整个工业设计时期中随同满足物质需求产品生产能力增长而发生的转变。事实表明,当产能不满足物质需求时,工业生产是以规模竞争优先;而当规模发展到极端而导致产能过剩并引发许多社会问题时,工业生产就转向创新竞争。竞争模式改变导致设计认知和理念的变化:从保证大规模物质生产、符合物质演变规律,即理性的系统化的设计,到满足人们对新的和美好生活的追求,并同时满足物质需求、精神需求和社会需求统一的由创意引领的设计。哪一个设计能使创新成功,取决于竞争,不仅仅是市场竞争,而且是在社会发展中的竞争。现在不是会不会设计的问题,而是设计有没有竞争力。中国正处在经济增长方式转变的关键时期,推动设计科学的研究,认识这些变化非常重要。本文提出了“竞争性设计”和“继承性设计”的概念,并将后工业设计时期称为竞争性设计时期。

Human-like torso features are essential in humanoid robots. In this paper problems for design and operation of solutions for a robotic torso are discussed by referring to experiences and designs that have been developed at Laboratory of Robotics and Mechatronics (LARM) in Cassino, Italy. A new solution is presented with conceptual views as waist-trunk structure that makes a proper partition of the performance for walking and arm operations as sustained by a torso.
