Dynamic Analysis of Electrically Assisted Turbocharger Rotor Considering Contact Effects in Nut Structures

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The rotor system of an electrically assisted turbocharger (EAT) is composed of multiple shaft components; The nonlinear connection and contact effects make it difficult to determine the system dynamic characteristics. To improve the modeling accuracy of EAT rotor system and evaluate the influence of contact between multi‐axis components and ...

Design and Multibody Dynamics Modeling of a Novel High‐Static‐Low‐Dynamic‐Stiffness Vibration Isolation Mechanism Based on Euler Buckling Characteristics

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Vibration isolation has long been a critical area of research, with the design of isolators based on the mechanical properties of Euler buckling beams representing one of the primary approaches. Traditionally, the focus has been on utilizing the negative stiffness characteristics of a post‐buckled Euler beam in parallel with positive stiffness

Proximity to wind turbines altered plant–pollinator dynamics in prairie and sagebrush ecosystems in Wyoming, USA

Nordic Journal of Botany, EarlyView.
Wind turbines influence several abiotic conditions in the environments they are sited in and may influence the behavior and movement of insect pollinators. It is unknown how operating turbines influence plant–pollinator interactions. To investigate if pollination dynamics could be affected by the presence of wind turbines, we recorded videos of ...
