DEVELOPMENT OF LINEAR MOTOR SERVO VALVE
Proceedings of the JFPS International Symposium on Fluid Power, 1996 Primarily in use at present is the nozzle flapper type servo valve providing with a torque motor.It is not in all cases appropriate for construction machines requiring large flow, owing to small control flow of the nozzle flapper.To deal with this situation, the linear motor servo valve using a magnet for a proportional solenoid has been developed.By ...

Advanced Intelligent Systems, Volume 8, Issue 3, March 2026.Insect‐scale crawling robots can traverse confined environments; nevertheless, their functionalities are predominantly restricted to sensing because of challenges in integrating actuated degrees of freedom. Herein, a miniature rotary electrostatic clutch is presented by incorporating cutting patterns in the clutch layer.

Advanced Intelligent Systems, Volume 8, Issue 3, March 2026.Female desert locusts dig underground to lay their eggs. They displace soil, rather than removing it, to create a tunnel. We analyze burrowing dynamics and 3D kinematics and design a locust‐inspired hybrid soft–stiff robot that reproduces this mechanism. The results show the natural strategy minimizes energy, whereas alternative patterns raise costs up

Quick-response servo amplifies small hydraulic pressure differences [PDF]
, 1966 Hydraulic servo, which quickly diverts fluid to either of two actuators, controls the flow rates and pressures within a hydraulic system so that the output force of the servo system is independent of the velocity of the mechanism which the system ...

Failure Mechanism of Asymmetric Large Deformations Under Repeated Mining in Roadways
Energy Science &Engineering, Volume 14, Issue 3, Page 1195-1212, March 2026.Principal stress‐evolution diagram at different advance positions of 42205 working face. ABSTRACT To address the challenge of controlling severe asymmetrical deformation in roadways subjected to repeated mining, this study (i.e., based on the engineering context of the Buertai Coal Mine) investigated the characteristics of the regional stress field in ...

Dynamic Modelling of Critical Infrastructures for Improved Disaster Habitation Recovery
Systems Research and Behavioral Science, Volume 43, Issue 2, Page 810-825, March/April 2026.ABSTRACT Natural disasters damage infrastructure systems that support housing habitability, leading to population displacement. Recovery efforts speed up infrastructure capacity restoration and, thereby, rehabitation by displaced residents. Current recovery policy analysis methods focus on individual infrastructure systems or overall community recovery
