On the influence of temperature on the cushioning ability of the hydraulic cylinders

Résumé

This paper presents some aspects related to the way the cushioning capacity of hydraulic cylinder is affected by the temperature variations of the hydraulic fluid. We have analysed the case of the hydraulic cylinders with cushioning systems, which act translational moving objects. The modification of the systems behavior is due to the significant variation of the hydraulic resistance with the viscosity of fluid. This leads to the modification of the hydraulic resistance of the cushioning system, responsible for braking the moving parts.
