Abstract High-end equipment always operate in low-speed and heavy-load working environments, highlighting the need for cam-lobe hydraulic motors with excellent speed stability (< 1 r/min) and ultrahigh-power rotary outpu...

Abstract With the development of fluid-power transmission and control technology, electro-hydraulic-driven technology can significantly improve the load-carrying capacity, stiffness, and control accuracy of stabilization...

The large-strain self-weight consolidation theory is widely used for the design of dredged material disposal sites and the treatment of hydraulically dredged slurries in the disposal sites. The self-weight consolidation ...

Abstract The current research mainly focuses on the flow control for the two-stage proportional valve with hydraulic position feedback which is named as Valvistor valve. Essentially, the Valvistor valve is a proportional...

Abstract Cam-lobe radial-piston hydraulic motors are widely used as rotation driving units for various marine machinery owing to their ultrahigh output torque (more than 100 kN m). A multi-row cam roller bearing (MCRB) i...

A liner system containing clay or bentonite-sand mixtures is installed on the bottom of a landfill to prevent contaminants from flowing into the surrounding ground. The influence of Ca2+ concentration and local settlemen...

As one of composition materials (asphalt, aggregate, mineral powder) for hydraulic asphalt concrete, the mineral powder has a messy process of manufacture. Comparatively, the cement is easily processed and available for ...

The case study of closely spaced twin tunnels excavated vertically beneath the adjacent Chaoyangmen station in Beijing, China is introduced. The existing subway station is part of the Beijing subway Line 2. The new recta...

The specimens of silty sand, standard sand and clay with different void ratios are prepared. By utilizing a multifunctional permeability test apparatus, a series of permeability tests are carried out under the conditions...

Tsunami-like waves pose a serious threat to coastal infrastructure, necessitating effective mitigation measures to reduce inundation and associated damage. This study uses a numerical wave tank (NWT) to investigate the h...

Abstract With the increasing demand to reduce emissions and save energy, hydraulic reservoirs require new architecture to optimize their weight, space, and volume. Conventional open reservoirs are large, heavy, and easil...

Abstract As electro-hydrostatic actuator (EHA) technology advances towards lightweight and integration, the demand for enhanced internal flow pathways in hydraulic valve blocks intensifies. However, owing to the constrai...

Abstract Hydroformed parts are widely used in industrial automotive parts because of their higher stiffness and fatigue strength and reduced weight relative to their corresponding cast and welded parts. This paper report...

In order to study disaster evolutionary process and failure characteristics of Yonglian tunnel of Ji'an-Lianhua highway under the effect of disturbance, taking F2 fault fracture zone as the research object, a large-scale...

Objective and MethodTo achieve rapid coalbed methane (CBM) extraction from broken-soft coal seams using surface horizontal wells, this study proposed a volume fracturing technology for coal seam roof using horizontal wel...

Culverts play a critical role in stormwater conveyance, roadway safety, and flood mitigation, particularly within low-lying urban communities vulnerable to extreme rainfall events. In Louisiana, increased rainfall intens...

Abstract The productivity decline of technological wells during in situ leaching (ISL) is primarily associated with clogging of well filters and the near-filter zone, leading to a significant increase in hydraulic resist...

Abstract The design of aircraft hydraulic pipeline system is limited by many factors, such as the integrity of aviation structure or narrow installation space, so the limited clamp support position should be considered. ...

This paper focuses on control systems for hybrid heat pumps that utilize the heat from return heat-ing water and outdoor air, designed to operate in district heating systems based on central heating plants. The aim of th...

Abstract When an output curve force is applied to a horizontal servo cylinder with a heavy load, the piston rod bears a dynamic partial load based on the installation and load characteristics, which significantly affects...
