A groundbreaking, unifying theory of computer science for low-cost, high-quality software
The Cognitive Dynamics of Computer Science represents the culmination of more than thirty years of the author's hands-on experience in software development, which has resulted in a remarkable and sensible philosophy and practice of software development. It provides a groundbreaking ontology of computer science, while describing the processes, methodologies, and constructs needed to build high-quality, large-scale computer software systems on schedule and on budget.
Based on his own experience in developing successful, low-cost software projects, the author makes a persuasive argument for developers to understand the philosophical underpinnings of software. He asserts that software in reality is an abstraction of the human thought system. The author draws from the seminal works of the great German philosophers-Kant, Hegel, and Schopenhauer-and recasts their theories of human mind and thought to create a unifying theory of computer science, cognitive dynamics, that opens the door to the next generation of computer science and forms the basic architecture for total autonomy.
* Four detailed cases studies effectively demonstrate how philosophy and practice merge to meet the objective of high-quality, low-cost software.
* The Autonomous Cognitive System chapter sets forth a model for a completely autonomous computer system, using the human thought system as the model for functional architecture and the human thought process as the model for the functional data process.
* Although rooted in philosophy, this book is practical, addressing all the key areas that software professionals need to master in order to remain competitive and minimize costs, such as leadership, management, communication, and organization.
This thought-provoking work will change the way students and professionals in computer science and software development conceptualize and perform their work. It provides them with both a philosophy and a set of practical tools to produce high-quality, low-cost software.

内容概要:本文详细探讨了杯形谐波减速器的齿廓修形方法及寿命预测分析。文章首先介绍了针对柔轮与波发生器装配时出现的啮合干涉问题,提出了一种柔轮齿廓修形方法。通过有限元法装配仿真确定修形量,并对修形后的柔轮进行装配和运转有限元分析。基于Miner线性疲劳理论,使用Fe-safe软件预测柔轮寿命。结果显示,修形后柔轮装配最大应力从962.2 MPa降至532.7 MPa,负载运转应力为609.9 MPa,解决了啮合干涉问题,柔轮寿命循环次数达到4.28×10⁶次。此外,文中还提供了详细的Python代码实现及ANSYS APDL脚本,用于柔轮变形分析、齿廓修形设计、有限元验证和疲劳寿命预测。 适合人群:机械工程领域的研究人员、工程师,尤其是从事精密传动系统设计和分析的专业人士。 使用场景及目标:①解决杯形谐波减速器中柔轮与波发生器装配时的啮合干涉问题;②通过优化齿廓修形提高柔轮的力学性能和使用寿命;③利用有限元分析和疲劳寿命预测技术评估修形效果,确保设计方案的可靠性和可行性。 阅读建议:本文涉及大量有限元分析和疲劳寿命预测的具体实现细节,建议读者具备一定的机械工程基础知识和有限元分析经验。同时,读者可以通过提供的Python代码和ANSYS APDL脚本进行实际操作和验证,加深对修形方法和技术路线的理解。
