A new friction model in hybrid pump-controlled asymmetric (single-rod) cylinder drive system
journal contribution
posted on 2020-08-14, 12:39 authored by Huankun Wang, Paul LeaneyHybrid pump-controlled asymmetric cylinder drive systems are implemented for energy saving
purposes in applications that do not require fast responses. Under low-velocity and low-pressure
conditions, the friction influence in the hybrid pump-controlled system is evident. Researchers
have developed various models to describe friction. These friction models are implemented based
on the relative motion of the contact surfaces, and they can be categorized into static friction and
dynamic friction models. For example, dynamic friction models are suitable for simulating the friction in hydraulic cylinder seals under lubrication conditions. Among the dynamic models, the
LuGre model can capture almost all static and dynamic friction behaviors at the macroscopic level;
for example, stiction, the Stribeck effect, and hysteresis. Thus, the LuGre model is suitable for
describing the friction in hydraulic cylinders. Because the friction force in the hydraulic cylinder is
mainly from the cylinder seal and seal deformation occurs under pressure due to its flexibility, the
friction in a hybrid pump-controlled hydraulic system is affected by the relative motion of the contact surfaces. Therefore, to investigate factors that affect the friction other than the relative motion
of the contact surfaces, the friction behaviors of a hybrid pump-controlled hydraulic system are
studied. Pressure difference and acceleration terms are introduced in the LuGre friction model,
and the simulated friction results of the updated LuGre model are compared with the measured
experimental results to validate the new friction model.
