A Design Environment for Kinematic Synthesis of Defect-Free Linkage Systems

该奖项的研究目标是开发新的技术，以克服使用自动计算机辅助设计技术获得无缺陷机械连接的固有困难，即所谓的运动学综合。最近的研究表明，对于平面和球面四杆机构，可以通过在设计者提供的期望任务附近的公差区域中进行随机搜索来实现这一点。目标是将这些结果推广到平面和球面六杆和八杆机构。其结果将是可靠的计算机辅助合成复杂的链接系统，这些系统超出了我们目前的能力。可交付的内容包括无缺陷连杆系统的综合软件、使用软件和硬件的演示和验证、研究成果的文档记录以及研究生和本科生的工程教育。这项研究将包括将运动学综合集成到现代计算机建模软件中。能够可靠地合成平面和球面六杆和八杆机构系统，虽然复杂，但能够满足设计者的目标，这将为目前不存在的创新提供机会。在职工程师、本科生和研究生将受益于运动学合成的商业集成，它为家庭、办公室、医院和工厂的自动化提供可靠、创新和低成本的机械运动。这将通过通过互联网上的视频呈现的软件和硬件设计的例子来演示。

The research objective of this award is to develop new techniques to overcome the inherent difficulty of obtaining defect-free mechanical linkages using automated computer-aided design techniques, known as kinematic synthesis. Recent research has shown that this can be achieved for planar and spherical four-bar linkages by a stochastic search in tolerance zones provided by the designer in the vicinity of a desired task. The goal is to extend these results to planar and spherical six-bar and eight-bar linkage systems. The result will be reliable computer-aided synthesis of complex linkage systems that are beyond our current capabilities. Deliverables include software for the synthesis of defect-free linkage systems, demonstration and validation using software and hardware, documentation of the research results, and engineering education at the graduate and undergraduate level.This research will include the integration of kinematic synthesis in modern computer modeling software. The ability to reliably synthesize planar and spherical six-bar and eight-bar linkage system that while complex are able meet the designers goals will provide an opportunity for innovation that currently does not exist. Working engineers, undergraduate and graduate students will benefit from the commercial integration of kinematic synthesis, which provides reliable, innovative, and low-cost mechanical movement in automation for the home, office, hospital, and factory. This will be demonstrated by example software and hardware design presented by video over the internet.
