“…There is a need for the performance of such a machine to be predicted, this has not as yet been established. In recent years, with the advent of the Bondgraph technique [1], the analysis of a complex hydrostatic system has become more streamlined than other existing methods [2][3][4][5][6][7]. This technique provides a structured approach in the modelling of complex physical systems and helps in the study of dynamic and steady state characteristics.…”

In this article the steady-state performance of a multi-plunger low-flow high-pressure hydraulic pump has been studied. The variation of the chamber volume with shaft rotation, along with the various flow and torque losses, demands a structured approach to arrive at its mathematical model. A bondgraph simulation technique has been used to model the system, where various losses are lumped in suitable resistive elements. Using the standard procedure, experiments have been conducted for a wide range of operating conditions. The trends of the various loss coefficients are identified. The performance of the pump has been experimentally verified.

In order to reduce the useless power of the missile-loaded hydraulic actuator, a new scheme that a variable-speed pumping source (VPS) is equipped on the missile-loaded hydraulic actuator is proposed in this study. Simulations in time-domain, frequency-domain and useless power are performed for the proposed scheme, and the results demonstrate that the new scheme is feasible. On the one hand, the performance of actuator has not been affected notably; on the other hand, the useless power for the actuator has been remarkably reduced.
