Design and Optimization of 200 Ton H- Type Hydraulic Press [PDF]

open access: yesE3S Web of Conferences, 2021
A hydraulic press is a machine using a hydraulic cylinder to generate a compressive force. The hydraulic press works on Pascal’s principle, which states that the pressure throughout a closed system is constant.

Relationship between the reciprocity of transfer functions for mechanical vibration systems and optimal design formulas of dynamic vibration absorbers

open access: yesMechanical Engineering Journal, 2022
Transfer functions are often employed to evaluate the vibration characteristics of mechanical and electrical systems. Within a group of transfer functions, some particular ones have the property that swapping the coefficients of the two terms in the ...

Simple exact solutions for designing an optimal mechanical dynamic vibration absorber combined with a piezoelectric LR circuit based on the H∞, H2, or stability criterion

open access: yesMechanical Engineering Journal, 2021
Multiplexing dynamic vibration absorbers (DVAs) provide better vibration control compared to that obtained with single-mass DVAs; however, their structure is more complicated and they are thus difficult to apply in practice.

Solidity Optimization for an H-Darrieus Wind Turbine

open access: yesDüzce Üniversitesi Bilim ve Teknoloji Dergisi, 2021
Solidity is one of the main factors that influence the performance of a wind turbine. The solidity of an H-Darrieus wind turbine is optimized in terms of blade number, chord length, and rotor radius to get the maximum power coefficient using Taguchi L16 (
