This SBIR Phase I project will develop a hydropneumatic accumulator for fluid power systems with specific applications to hybrid vehicles. The unique aspect of the accumulator design is the leaf spring construction which has the necessary air channel communications that in turn influences the heat transfer characteristics. The ability to influence the heat transfer will in turn provide a way to improve the regenerative aspects of the accumulator. The problem is significant in single accumulator systems. The broader/commercial impacts of the proposed project will be in the many application areas of fluid power systems. In the specific application to a hybrid vehicle, there could be a fuel economy improvement. There will be a trade-off between vehicle weight and reduced fueling benefits. However, any efficiency in a fluid power system would translate into improved system efficiency, resulting in broad commercial impact.

该 SBIR 第一阶段项目将开发一种用于流体动力系统的液压气动蓄能器，专门应用于混合动力汽车。蓄能器设计的独特之处在于板簧结构，其具有必要的空气通道连通，进而影响传热特性。影响热传递的能力反过来将提供一种改善蓄能器再生方面的方法。这个问题在单蓄能器系统中很严重。拟议项目的更广泛/商业影响将涉及流体动力系统的许多应用领域。 在混合动力汽车的具体应用中，可以提高燃油经济性。 车辆重量和燃油效益降低之间需要权衡。 然而，流体动力系统的任何效率都会转化为系统效率的提高，从而产生广泛的商业影响。
