This article presents a comprehensive, multidisciplinary overview of the development powertrain technologies for energy-efficient heavy-duty earthmoving machines. The equipment industry has been among biggest contributors to emissions globally. However, due high power demand and structures, improving energy efficiency mobile machines pressing challenging task in industry. To cope with this chal...

in this paper, a complete model of an electro hydraulic driven dry clutch along with its performance evaluation has elucidated. through precision modeling, a complete nonlinear physical and full order sketch of clutch has drawn. ultimate nonlinearities existent in the system prohibits it from being controlled by conventional linear control algorithms and to compensate the behavior of the system...

In mobile hydraulic machines, like excavators, backhoe loaders, wheel loaders, and forklift trucks, haptic human-machine interfaces are not in use. Today, the machines are operated with mechanical-hydraulic joysticks. Each joystick axis controls a single hydraulic actuator. This leads to not very easy to use operational concepts. Since electrohydraulic systems with electronic joysticks are avai...

  Introduction: The Republic of Korea has developed a national standard based on which diagnostic X-ray equipment must be tested every 3 years. Accordingly, the performance of X-ray equipment used in all hospitals is evaluated by national certification bodies in compliance with the safety management regulations for X-ray equipment. However, if the equipment i...

Introduction The main goal of this study was to perform quality control test on all radiography units operating in Golestan province of IRAN. Materials and Methods Forty-four X-ray units were examined based on general accepted programs for quality control. Eight parameters including kVp accuracy, kVp reproducibility, mA-time reciprocity, exposure linearity, exposure reproducibility, timer accur...

Modern methods of recycling scrap tungsten pseudo-alloys are considered. The improvement the method electroerosive dispersion conductive granules by strengthening its electrohydraulic action for effective disintegration into micro-components is discussed.
