Presidential Young Investigator Award: Automated Mechanical Systems Synthesis

这项研究将产生不同的数值算法公式，这些算法将被集成在一起，以开发一套概念设计、运动学和动力学分析以及分析/实验机械系统优化工具。将开发一个基于计算机的自动化机械系统“Inventor”，该系统在计算机终端生成并绘制受设计者指定约束的候选机械系统。将产生用于分析非线性运动学和动态机械系统的高效数值方法，包括用于多体机械系统的组合集中/分布参数动力学建模方案和并行处理的动力学分析算法。此外，将通过开发集成交互、用户指导、参数优化、彩色计算机图形和分析/实验相结合的方法(利用原型响应的在线、计算机控制的数据采集)的优化工具，来实现针对规定的动态响应的原型系统的系统尺寸确定和调整。

This research will generate alternate formulations of numerical algorithms that will be integrated to develop a package of conceptual design, kinematic and dynamic analysis, and analytical/experimental mechanical system optimization tools. An automated computer-based mechanical system "inventor" will be developed that generates and draws at the computer terminal candidate mechanical systems subject to designer-specified constraints. Numerically efficient methods for the analysis of nonlinear kinematic and dynamic mechanical systems will be generated, including a combined, lumped/distributed parameter dynamic modeling scheme and a parallel-processing dynamic analysis algorithm for multiple-body mechanical systems. Further, the systematic dimensioning and tuning of prototype systems for prescribed dynamic response will be implemented by developing optimization tools that integrate interactive, user-guided, parametric optimization, color computer graphics, and combined analytical/experimental methods (utilizing on-line, computer-controlled data acquisition of prototype response).
