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.

Automated Tool

This paper presents a graph grammar based automated tool that can generate bond graphs of various systems for dynamic analysis. A generic graph grammar based representation scheme has been developed for different system components and bond graph elements. Using that representation, grammar rules have been developed that enable interpreting a given system and generating bond graph through an algorithmic search process. Besides, the paper also demonstrates the utility of the proposed tool in classrooms to enhance value in bond graph based system dynamics education. The underlying technique, various examples and benefits of this automated tool will be highlighted.

Efficiency And Reliability

In order to increase the efficiency and reliability of dynamic and static force analysis for spatial multibody systems containing the coupling of multi-energy domains, a method based on gyrobondgraph is introduced. The procedure of modeling spacial multibody systems by bond graphs and its dynamic principle are described. The unified formulae of driving moment and constraint forces at joints are derived based on gyrobondgraph, they are easily generated on a computer in a complete form. As a result, the very difficult algebraic problem caused by differential causality and nonlinear junction structure can be overcome, and the automatic dynamic analysis of multibody systems on a computer is realized. By a practical example, the validity of this procedure is illustrated.

Abstract One commonly used pump in the petroleum sector is the Progressing Cavity Pump (PCP). The PCP is a type of positive displacement pump that is used as an artificial lifting system which consists of a helical rotor and elastomeric stator. A mathematical solution to a PCP system model requires that we solve a partial differential equation system. The solution is inherently complex and requires considerable computational time. This paper uses the bond graph formalism, which is based on energy and information flow, to implement a model of a PCP system. Its purpose is to predict the dynamic response of the PCP system when it is subjected to a specific reservoir condition. Specifically focusing on the rod string, the torsional effects are captured by a lumped segment approximation. The software 20-Sim© was used to simulate a realistic PCP system application scenario. The model presented in this paper is able to determine the prime mover, rod string, and other component requirements. This paper shows that the multi-body lumped segment model is a useful way to simulate the rod string performance. The bond graph is effective at modeling the PCP system which contains elements from different energy domains.
