Designing ZV and ZVD Input Shapers Using the Designed Fixed Output Response Method to Suppress Residual Vibration of Overhead Crane Systems With Trolley Traveling and Payload Hoisting

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Classical Zero Vibration (ZV) and Zero Vibration and Derivative (ZVD) input shapers are designed around a fixed nominal natural frequency and cannot accommodate the time‐varying dynamics introduced when an overhead crane simultaneously travels and hoists a payload.

Mechanical and Impact Response of Adhesively Bonded ASA/PA12 Sandwich Structures Produced by Fused Filament Fabrication

open access: yesPolymer Engineering &Science, EarlyView.
Adhesively bonded ASA/PA12 FFF sandwich structures reveal that interfacial compliance governs mechanical performance. Cyanoacrylate enhances strength but induces brittle failure, while polyurethane improves ductility and impact resistance, demonstrating that adhesive properties and stacking sequence are critical design parameters for optimizing multi ...

The iPP Printing Paradox: Interlayer Adhesion Through Crystallization

open access: yesPolymer Engineering &Science, EarlyView.
In fused filament fabrication of isotactic polypropylene, high molecular weight and a high print speed increase the shear during deposition. This shear promotes the formation of the ductile β‐phase at the interphase, which improves interlayer adhesion, as shown by an eightfold increase in fracture energy measured via a T‐peel test on two printed ...

Friction‐Corrected In‐Situ Viscosity Measurement in Material Extrusion: A Force‐Based Method Validated Against Capillary Rheometry Using Identical Nozzle Geometry

open access: yesPolymer Engineering &Science, EarlyView.
In the filament force measurement (FFM), the friction of the solid filament, determined in an open‐bore reference, is subtracted from the measured extrusion force to obtain the capillary force. The resulting apparent viscosity is compared with high‐pressure capillary rheometry (HPCR) using the identical printer nozzle in both instruments.
