Differential Collision Models

该项目旨在对高性能轴向活塞静压泵的控制和密封要求进行动态分析。 在过去的三十年中，大量的信息已经被添加到描述标准斜盘泵设计的控制要求的文献中;然而，几乎没有关于斜盘安全壳的文章。 此外，在泵行业本身，一些创新的公司已经确定了使用非标准斜盘设计的某些优点，该设计利用可变的主斜盘角度和固定的副斜盘角度;但是，同样，文献中没有添加任何内容来一般性地描述和应用这些优点到广泛的泵设计中。 在此确定本设计的控制和遏制要求。 此外，这项工作将进一步超越目前的做法，考虑一般情况下，当主和副斜盘的角度变化。 这项研究的结果将是确定这种新型机器的机械和控制要求，并从理论上证明实施设计的优势，如果成功的话，这项研究的工作将用于显着提高性能的轴向柱塞泵，广泛用于流体动力应用的今天。 性能的提高将体现在运行效率的提高和泵的静音上。 这些改进将通过优化泵的内部压力瞬变来实现，以适应机器正常工作循环期间可能在很大范围内变化的操作条件。 第二个影响是减少泵内阀板的腐蚀。 这项工作的总体目标是减少浪费，提高轴向柱塞泵技术的生产率。 这些目标的成功实现将体现在更低的泵运行成本，更长的产品寿命，以及减少产品维护和设计的工程时间。

This project is aimed at conducting a dynamic analysis of the control and containment requirements for a high performance, axial piston, hydrostatic pump. Over the last thirty years, a great deal of information has been added to the literature which describes the control requirements for a standard swash-plate pump design; however, virtually nothing has been written on the topic of swash-plate containment. Also, within the pump industry itself, a few innovative companies have identified certain advantages in using a non-standard swash-plate design, which utilizes a variable primary swash-plate angle and a fixed secondary swash-plate angle; but, again, nothing has been added to the literature to generally describe and apply these advantages to a broad range of pump designs. In this ascertain the control and containment requirements for this design. Furthermore, this work will go a step beyond current-day practice by considering the general case when both the primary and secondary swash-plate angles vary. The outcome of this study will be to identify the mechanical and control requirements for this novel machine and to theoretically prove the advantages of implementing the design.If successful, the work of this research will be used to significantly enhance the performance of axial piston pumps that are widely used in fluid power applications today. The improved performance will be demonstrated in increased operating efficiency and quieter pumps. These improvements will be achieved by optimizing the internal pressure transients of the pump for operating conditions that may vary over a wide range during the normal duty cycle of the machine. A secondary impact will be to reduce valve-plate erosion within the pump. The overall objectives of this work are reduce waste and to increase the productivity of axial-piston pump technology. The successful accomplishment of these objectives will manifest itself in lower pump operating costs, longer product life, and a reduction in engineering time for product maintenance and design.
