Hydraulic system provides smooth control of large tracking and antenna drive systems at very low tracking rates [PDF]

open access: yes, 1967
Hydraulic system provides smooth control of large tracking and antenna drive systems at very low tracking rates. This configuration modifies a series connection of the drive motors with compensating orifices to offset the effects of drain line loss ...

On the Deformation Behavior of Metastable CrMnNi Steels Processed by Directed Energy Deposition in Different Temperature Regimes

open access: yesAdvanced Engineering Materials, EarlyView.
In the present study, metastable CrMnNi steels with varying chemical compositions and a concomitantly altered stacking fault energy are processed via directed energy deposition and afterwards tested via tensile tests at different temperatures. The present study shows the influence of the manufacturing process on the elemental deformation mechanisms for

Hydraulic drive boom lifting mechanism [PDF]

open access: goldIOP Conference Series: Materials Science and Engineering, 2019
The paper presents the calculation of the pressure of the hydraulic cylinder of the boom at the inlet to the throttle, which regulates the speed of lowering the boom with a load, which provides a non-cavitation operation mode of the hydraulic drive. The pressure calculation takes into account the change in the angular acceleration of the boom with a ...

The Structural Refinement of Commercial‐Purity Copper Processed by Equal Channel Angular Pressing with Low Strain Amplitude

open access: yesAdvanced Engineering Materials, EarlyView.
Equal channel angular pressing of commercial pure copper under low strain amplitude (≈0.48) induces concurrent continuous and localized discontinuous dynamic recrystallization, forming a duplex structure influenced by strain heterogeneity and recovery. Moderate hardening after 4–12 passes results from progressive high‐angle grain boundary formation via
