This paper investigates the performance of an experimental hydrostatic drive system in the steady state that includes a linear actuator and lever mechanism. The study uses both system modeling and empirical test data for evaluation. A system model was used to pinpoint major parameters responsible for energy loss. Tests at different actuator speeds revealed that system resistances changes with actuation speed in a non-linear fashion. The leakage and throttle resistances shown decreasing trend with actuator speed whereas the friction force varied proportionally with the piston velocity. Experimental results indicated that increasing actuator speed slightly decreases leakage and throttle resistances, while the efficiency of the hydrostatic drive improves from 74 to 80% at piston speeds ranging from 2 to 7 cm/s. These findings are particularly useful for engineers in selecting appropriate hydrostatic drives and offer valuable insights into the control aspects and preliminary design of similar systems. Furthermore, the results suggest opportunities for cost-effective solutions. This research highlights the critical role of precise system modeling and experimental validation in improving the performance and efficiency of hydrostatic drive systems.
