Modeling of hydraulic support system for large structures
Nihon Kikai Gakkai ronbunshu, 2021 In the control of a large structure, hydraulic equipment is often used because it requires a large output. In this study, we focus on the telescope as an example of a large structure, and model its hydraulic support system and analyze its characteristics

Experimental validation of hydraulic support system for large structures
Nihon Kikai Gakkai ronbunshu, 2021 In the control of a large structure, hydraulic equipment is often used because it requires a large output. In this study, we focus on a telescope as an example of a large structure, and experimentally verify the basic characteristics of the hydraulic ...

Quantum Field Theory Under the Influence of External Conditions (QFEXT09), 2010 We consider semitransparent pistons in the presence of extra dimensions. It is shown that the piston is always attracted to the closest wall irrespective of details of the geometry and topology of the extra dimensions and of the cross section of the piston. Furthermore, we evaluate the zeta regularized determinant for this configuration.

The influence of coolant scale deposit inside the internal combustion engine on the piston and cylinder deformations [PDF]
Transport, 2005 This paper presents the analysis of the influence of engine coolant scale deposits on the deformations in the piston †cylinder pair. The results of carried out calculations enable to make more precise evaluation of cylinder repair dimensions.

A new model of fluid flow to determine pressure balance characteristics [PDF]
, 2013 Some projects such as the EUROMET project 463 have underlined the lack of agreement between experimental measurements and calculations by the finite element method (FEM), used to determine the piston fall rate of a high-pressure balance used in primary ...
