This Small Business Innovation Research (SBIR) Phase II project proposes to develop a fully functional turnkey regenerative semi-active shock absorber for heavy-duty transit buses and other commercial vehicles. An appreciable amount of energy is lost in a typical suspension as heat, especially in heavy vehicles. Existing technologies have been unable to efficiently capture this energy in a cost-effective manner. This project entails hydraulic and electronic model optimization, design of vehicle-ready prototypes, fabrication, lab testing, installation, and operational testing of a hydraulic adaptive damping energy harvesting system. The objective of the project is to demonstrate real-world benefits of an efficient, adjustable damping regenerative shock absorber on a transit bus in operation with a municipal transit agency. Emphasis will be on efficiency improvements, semi-active ride control, and application specific integration requirements to ensure seamless installation and operation. Work will culminate in a fully fielded pilot demonstration and quantification of regenerated energy (improved fuel efficiency) and ride improvement benefits using the regenerative semi-active shock absorber. The broader impact/commercial potential of this project is significant if the challenges of inexpensively, reliably, and efficiently capturing suspension energy are overcome. The technology has the potential to save millions of dollars per year in fuel for large fleets, and significantly reduce carbon emissions in the United States and abroad. Effectively incorporating an aftermarket or OEM retrofit-able regenerative energy capture system may open doors to many new regenerative technologies in the transportation and automotive sector, facilitating significant reductions in waste energy. In addition, the research may lead to enabling technology for compact, sealed, and efficient hydraulic actuators and energy harvesters across several industrial applications. This may have applications in other fields such as off grid marine (hydrokinetic) energy, aerospace actuators, heavy machinery dampers, orthotics/prosthetics, and robotics.

这个小企业创新研究(SBIR)二期项目计划开发一种全功能交钥匙再生式半主动减震器，用于重型公交公交车和其他商用车。在典型的悬架中，特别是在重型车辆中，有相当数量的能量以热量的形式损失。现有的技术一直无法以具有成本效益的方式有效地捕获这种能量。该项目包括液压和电子模型的优化、车辆样机的设计、液压自适应减振能量收集系统的制造、实验室测试、安装和运行测试。该项目的目的是展示一种有效的、可调节的阻尼式再生减震器在与市政公交机构合作运营的公交上的实际好处。重点将放在提高效率、半主动行驶控制和特定于应用的集成要求上，以确保无缝安装和运行。这项工作将在使用再生半主动减震器的再生能源(改进的燃油效率)和平顺性改善效益的全面试点示范和量化中达到高潮。如果能克服廉价、可靠和高效地捕获悬浮能量的挑战，该项目的更广泛的影响/商业潜力将是显著的。这项技术有可能每年为大型船队节省数百万美元的燃料，并显著减少美国和海外的碳排放。有效地结合售后市场或OEM可改装的可再生能源捕获系统，可能会为交通和汽车部门的许多新的再生技术打开大门，促进显著减少浪费能源。此外，这项研究可能导致在几个工业应用中实现紧凑型、密封和高效的液压执行器和能量收集器的技术。这可能会在其他领域有应用，如离网海洋(流体动力)能源、航空航天执行器、重型机械减振器、矫形术/假肢和机器人。
