Article Synopsis
- Before introducing a new engine in civil aviation, it must meet strict safety regulations, especially concerning potential damage from engine part ingestion, like a tooth fragment, which can lead to severe failures in the gear rim.
- The paper outlines a method for modeling the behavior of case-hardened spur gears, utilizing the Johnson-Cook material model to analyze plastic behavior, fracture characteristics, and the effects of the surface-hardened layer.
- To validate the findings, the researchers used a specialized gearbox test rig for controlled fragment ingestion and conducted a simplified experiment to examine the risk of tooth flank cracks.
Introduction: Following lockdown periods and restricting public health measures in response to the COVID-19 pandemic, respiratory tract infections (RTIs) rose significantly worldwide. This led to an increased burden on children's hospitals compromising medical care of acutely and chronically ill children. We characterized changes in the epidemiological pattern of circulating respiratory viral infections.
View Article and Find Full Text PDFTorsion adapters in lower limb prostheses aim to increase comfort, mobility and health of users by allowing rotation in the transversal plane. A preliminary study with two transtibial amputees indicated correlations between torsional stiffness and foot alignment to increase comfort and stability of the user depending on the gait situation and velocity. This paper presents the design and proof-of-concept of an active, bio-inspired prosthetic shank adapter and a novel approach to create a user-specific human-machine interaction through adapting the device's properties.

The measurement of these movements, particularly in dynamic gait situations, poses a challenging task. This paper presents the realization of a measurement concept based on multiple optical 2D-motion sensors.
View Article and Find Full Text PDFA sensor system for measuring the relative movement between prosthetic socket and residual limb based on a 2D-motion sensor is introduced and thoroughly tested experimentally. The quantitative analysis of test rig evaluation is used to identify advantageous sensor settings and liner configurations. Considering these favorable settings, sensor functionality is quantified to errrel=0.
