Research on compliance steers of strut type front suspension subject to lateral force and longitudinal force during cornering

Nihon Kikai Gakkai ronbunshu
In this paper, we conducted research on compliance steering with respect to lateral force and tire drag force (longitudinal force) in order to achieve good steering feel and smooth yaw motion, focusing on strut-type front suspensions widely used in front-

Granular Impact: A Grain-scale Approach

, 2015
This work summarizes a series of studies on two-dimensional granular impact, where an intruding object strikes a granular material at high speed. Many previous studies on granular impact have used a macroscopic force law, which is dominated by an ...

Mechanochromism of Glassy Polymers Enabled by a Loop‐Forming Supramolecular Mechanophore

Advanced Functional Materials, EarlyView.
The supramolecular mechanophore LOOP is covalently introduced into glassy polymers, capable of reporting force‐induced pre‐failure damage and local fracture events in polymer glasses. Under different mechanical deformation modes, including grinding, tensile stretching, and scratching, LOOP probes irreversible events in polymer glasses through a ...

Structural fatigue assessment of a fixed mono-pile platform

Advances in Mechanical Engineering, 2016
Fatigue assessment of fixed offshore platforms is essentially important to ensure their structural safety. Because of the small-scale leg diameter, these structures are often drag dominated, and linearized wave force is often utilized for the fatigue ...

Analysis of force and impulse of a hydrophobic rod rotating into water

Micro and Nano Systems Letters, 2019
This paper investigates the change of the relative magnitudes of force and impulse components generated by the rotational motion of a hydrophobic carbon rod moving into water from the water surface, by varying the rod length. Whereas added mass force and

Motion of a heavy impurity through a Bose-Einstein condensate

, 2004
We study motion of a point-like impurity in a Bose-Einstein condensate at T=0. By solving the Gross-Pitaevskii equation in a perturbative manner we calculate the induced mass of the impurity and the drag force on the impurity in 3D, 2D and 1D cases.

Tissue‐Stimulator Platform for Electrically Stimulating Pancreatic β‐Cells for Long‐Term Functional Regulation

Advanced Functional Materials, EarlyView.
We present a tissue‐stimulator platform for seamless electrode integration with pancreatic tissue, applying uniform electrical stimulation through optimized design with biohybrid 3D printing. Advantageous effects of electrical stimulation on β‐cell function were observed, including enhanced calcium signaling, islet morphology, and maturation.
