A profiled chamber metering pump (PCMP) is a new type of positive-displacement vane pump which is composed of a special stator and a rotor–slide assembly. The face-shaped curve of the inner chamber of the stator is formed by means of two quarter circular arcs and two quarter noncircular arcs, and one of the two quarter noncircular arcs is defined as transition curve. The geometry of the transition curve directly affects the dynamic performances of the pump system, including its mechanical vibration, friction, wear, and kinetic losses. This paper discusses a set of dynamic analysis methods that combine kinetic loss control with vibration control for optimization of the transition curve of the PCMP. At first, basic conception and work line on the method are explained. In a second step, by means of force analysis, a kinetic loss model is established. Then, the model is used to examine a group of vibration optimized curves in polynomial form, and kinetic losses caused by different mechanical resistance forces are calculated. Finally, through a comparison analysis together with vibration and kinetic losses, comprehensive optimal transition curves can be obtained.

Experimental Findings

A passively controlled infinitely variable transmission modeled and experimentally investigated by Cyders (2012), has potential to be combined with a number of different types of mechanisms. The mechanism’s incorporation into a hydraulic pump has many applications of interest; the CVT approach to a positive-displacement pump could provide a combination of the advantages of both positive-displacement and centrifugal pumps in one machine. This work had two main objectives: first, an inverse dynamic analytical model was developed using piece-wise techniques that simulated the behavior of the CVT/PD pump system. Second, this simulation was compared against experimental results, which were generated from data taken from an example system prototype. Predictions were made using an inverse-dynamics model, and were compared against experimental findings generated from a prototype of the system. The simple approach to modeling provided results sufficient to describe the overall pressure-flowrate behavior of the pump at low speeds, but a more sophisticated dynamic approach is still necessary to improve model agreement at high speeds when second-order effects begin to dominate.
