Investigating the Effect of Inclination Angle and the Influence of Scan Parameters on the Appearance and Thermal and Mechanical Properties of Filigree Tension Rods of LPBF‐Manufactured NiTi Shape‐Memory Alloys

Advanced Engineering Materials, EarlyView.
This article investigates the dependence of the properties on the manufacturing orientation in the form of the inclination angle to the build plate of LPBF‐fabricated NiTi rods with a diameter of 150–220 µm. Metallographic, chemical, thermal, and mechanical characterization show behavior under identical manufacturing conditions that ranges from ...

Programmable Soft Actuator with Multi‐Responsiveness Based on Conductive MOF‐Liquid Crystal Polymer Composite

Advanced Functional Materials, EarlyView.
A sequential dual‐alignment strategy independently programs the orientation of conductive metal‐organic framework (c‐MOF) microrods and liquid crystals within a composite film. This approach creates an asymmetric bilayer structure that enables precise, multi‐responsive actuation.

Calibration of industrial robots with pneumatic gravity compensators [PDF]

2017 IEEE International Conference on Advanced Intelligent Mechatronics (AIM), 2017
The paper is devoted to the stiffness modeling of heavy industrial robots with pneumatic gravity compensators. The main attention is paid to the identification of elastostatic parameters and calibration accuracy. To identify the desired set of parameters two-step identification procedure is developed. To reduce impact of the measurement errors, the set
