EFFECT OF PRELOAD OF ANGULAR CONTACT BALL BEARINGS ON LIFE OF BEARINGS [PDF]
Scientific Journal of Silesian University of Technology. Series Transport, 2014 Angular contact ball bearings are commonly used in such situations when you need to reach high bearing stiffness. However, a significant stiffness increase can be achieved only through the introduction of preload to the angular contact bearings.

A Soft Robotic Fish With a Dielectric Elastomer Actuator Body and Negative Stiffness Spine
Advanced Robotics Research, EarlyView.This work introduces a bio‐mimetic soft robotic fish driven by fiber‐reinforced dielectric elastomer actuators integrated as its body. By prestretching this active skin against a flexible spine, a negative stiffness system is created, enabling large‐amplitude bending.

Advanced Science, EarlyView.This study presents a novel 4D bioprinting platform for engineering biomimetic musculoskeletal grafts. By tuning the mechanical properties of support baths, we enhance tissue fusion, collagen alignment, and cell differentiation. Using this strategy, we successfully fabricate scaled‐up, anisotropic tissues such as meniscus, articular cartilage, and ...
