Holistic Measurement of the Friction Behavior of Wet Clutches

Lubricants
The safe and efficient torque transmission of wet disk clutch systems requires high coefficients of friction. To achieve good controllability and high comfort, a positive slope of the coefficient of friction over sliding velocity is ensured by a ...

Characterization and Selection of Contractile Actuators for Soft Robotics Operating in the Quasistatic Regime

Advanced Intelligent Systems, EarlyView.
We developed methods to characterize soft contractile actuators using force–displacement measurements in the passive state and the total force in the active state and define the operational range of thermal, electrothermal, and pneumatic muscles. A graphical method enables the selection of an actuator based on the required mechanical force–displacement

A methodology for image-based measurement of plate movement in disengaged wet clutches

Scientific Reports
The drag loss behavior of a disengaged wet clutch is influenced, among other things, by the movement of the plates. Therefore, knowledge about the plate movement is essential for investigating and optimizing the drag loss behavior.

Efficiency of Bevel and Hypoid Gears—Test Rig Development and Experimental Investigations

Machines
The efficiency of bevel and hypoid gears is, alongside load capacity, one of their most important design criteria. To consider the efficiency of bevel and hypoid gears during the development and design process, validated calculation methods based on ...

Balancing Exploration and Exploitation Through a Sequential Hybrid of Roach Infestation and Mayfly Algorithms for Constrained Engineering Design Optimization

AI &Innovation, EarlyView.
ABSTRACT Maintaining an effective balance between exploration and exploitation is essential during optimization processes, from mathematical functions to more complex problems such as constrained engineering design optimization, particularly when addressing highly nonlinear issues with numerous local optima and strict feasibility requirements.

Influences of different parameters on selected properties of gears for robot-like systems

Frontiers in Robotics and AI
For a drive unit for axes of robots and robot-like systems (RLS) usually a motor-gearbox arrangement is chosen due to its high-power density. The combination of a high-ratio gearbox and a high-speed electric motor ensures a very compact and efficient ...

The rain feels different under the same umbrella: Experiences with poverty across LGBTQ subgroups

American Journal of Community Psychology, EarlyView.
Abstract Population‐based survey data have demonstrated that LGBTQ communities report varying rates of economic insecurity, yet very little research directly assesses how pathways into and experiences with poverty look different among subgroups at the intersections of sexual orientation and gender identity (SOGI).

Technical validation of the Predictive Optimal Water and Energy Irrigation (POWEIr) controller for solar-powered drip irrigation

Smart Agricultural Technology
To feed the growing population, agriculture production must be intensified using existing resources. Sustainable agriculture intensification is particularly important in low and middle income countries (LMICs), which disproportionately experience food ...

Australia's Migration Strategy: An Effective Response to Migrant Worker Exploitation?

Australian Journal of Social Issues, EarlyView.
ABSTRACT A series of publicised migrant worker injuries and deaths has drawn attention to the issue of migrant worker exploitation (MWE) in Australia. In response, the Australian Government has included ‘Tackling Worker Exploitation’ as a key area of its Migration Strategy which it introduced in 2023. However, it is unclear how effective the Strategy’s
