Electrohydraulic Stewart platform is a multi-input and multi-output mechanical-hydraulic coupling system, which has the advantages of large power-to-weight ratio high accuracy. It been widely used in construction machinery, aerospace, other fields. In actual working process, especially high-speed motion, movement process will produce impact vibration then affect stability, accuracy, service lif...

In this study, solutions for machinery layout with the aim of reducing transportation costs will be discussed. To do this, imperialist competitive algorithm (ICA), which is a very complicated and effective meta-heuristic algorithm is introduced. In the offered algorithm, different kinds of machinery layout are considered in single-row as country and then the best possible layout is developed ba...

Sediment abrasion may cause the removal of material and efficiency loss to hydraulic machinery (hydro-turbine, pump, etc.), which worsen internal flow endanger safe operation machines. As is caused by impact sediment on solid surface, movement particles determines wear intensity. To understand mechanism machinery, motion characteristics asymmetric solid–liquid two-phase in a sediment-laden arou...

Abstract Because of complex and strong coupling system, the precision adaptability underground robots are greatly restricted. Based on newly developed intelligent heavy-load robot which is still a gap to fill in current coal mine machinery, this paper proposes new dynamic cooperative optimization control algorithm. Firstly, strongly coupled Multi-disciplinary Design Optimization system decouple...

Abstract Purpose Sustainable crop production could contribute to feed and fuel for the ever-increasing global population. The use of heavy agricultural machinery has improved efficiency farming operations increased food since 1950s. But their negative impact on soil includes changing structure resulting in deteriorating productivity environmental quality is being noticed several decades. purpos...
