Validation of a 1-D Elastohydrodynamic lubrication model [PDF]
MATEC Web of Conferences, 2019 The sealing performance of a hydraulic cylinder depends on the characteristics of three essential elements: the rod, the seal and the fluid. To predict the behaviour of a hydraulic seal, including the friction force and leakage rate, a series of ...

Optimal Design of the Sealing Structure of a Hydraulic Cylinder on the Basis of a Surrogate Model
Advances in Materials Science and Engineering, 2020 In this study, a finite-element simulation model was established for a two-dimensional hydraulic cylinder seal structure with highly nonlinear materials and contacts for achieving the optimal sealing effect with the structure. The effects of gaps as well

Chaotic rotation of a towed elliptical cylinder [PDF]
, 2014 In this paper I consider the self-excited rotation of an elliptical cylinder towed in a viscous fluid as a canonical model of nonlinear fluid–structure interactions with possible applications in the design of sensors and energy extraction devices. First,
