This Faculty Early Career Development (CAREER) award supports research that will focus on the generation, analysis and optimization of tensegrity structures. Tensegrity represents a class of structures composed of members in compression and tension in a self-equilibrated state. In this project, tensegrity systems are studied to conceive rapidly erected structures for traditional civil applications. However, the outcomes of this award extend beyond architecture and structures as tensegrity systems have been explored for a wide variety of engineering applications including metamaterials, planetary landers, soft robotics, as well as to model the mechanical behavior of biological cells. Although tensegrity structures have received significant interest among scientists and engineers, there is still no unifying theory on their generation and behavior. This research project thus seeks to develop a morphological framework that integrates design criteria with assembly and kinematics while providing architectural design freedom. The framework enables control over the behavior of tensegrity structures by decomposing complex systems into elementary tensegrity units. Inspired by tensegrity’s artistic origin, the research will also be complemented by developing learning modules centered on objects at the intersection of art, science, and engineering, exploring object-based learning in collaboration with educational experts and students.The goal of the research project is to develop a theoretical understanding of how morphology can be used to define the stability, equilibrium, deployability, structural response, sensing, and control in complex tensegrity structures. Specifically, the research approach includes a) understanding the relationship between cellular composition and mechanical behavior in tensegrity structures, b) enhancing the construction, analysis, sensing and control of tensegrity structures, and c) deriving a morphological framework for the generation and optimization of tensegrity structures with predefined and transformable forms, as well as tunable mechanical behaviors. To accomplish these objectives, a method that links topology identification and form finding through the cellular composition of tensegrity systems with cells being elementary tensegrity units will be explored. It is hypothesized that tuning the cellular composition of tensegrity structures along with their structural parameters can lead to desired shapes, optimized mechanical performance, and advantageous control methods. This project will allow the PI to advance the knowledge base in tensegrity systems and establish his long-term career in structural morphology.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该学院早期职业发展（CAREER）奖支持专注于张拉整体结构的生成、分析和优化的研究，张拉整体代表了一类由处于自平衡状态的压缩和拉伸构件组成的结构。研究系统的目的是为传统土木应用构想快速搭建的结构。然而，该奖项的成果超出了建筑和结构的范畴，因为张拉整体系统已被探索用于各种工程应用，包括超材料、行星行星。尽管张拉整体结构引起了科学家和工程师的极大兴趣，但该研究项目仍然没有关于其生成和行为的统一理论。该框架将设计标准与装配和运动学相结合，同时建筑设计自由，该框架可以通过将复杂系统分解为基本张拉整体单元来控制张拉整体结构的行为，该研究也将受到张拉整体艺术起源的启发。辅以以艺术、科学和工程交叉领域的对象为中心的学习模块，与教育专家和学生合作探索基于对象的学习。该研究项目的目标是对如何使用形态学进行理论理解具体来说，该研究方法包括 a) 理解张拉整体结构中的细胞组成和机械行为之间的关系，b) 增强构造、分析和传感。和张拉整体结构的控制，以及c)推导出用于生成和优化具有预定义和可变形形式的张拉整体结构以及可调机械行为的形态框架。为了实现这些目标，一种通过以单元为基本的张拉整体系统的单元组成将拓扑识别和形式发现联系起来的方法。将探索张拉整体单元。人们重新认识到，调整张拉整体结构的单元组成及其结构参数可以产生所需的形状、优化的机械性能和有利的控制方法，该项目将使 PI 能够推进知识库的发展。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
