The internal cushioning systems of hydraulic linear actuators avoid mechanical shocks at the end their stroke. design where piston with perimeter grooves regulates flow by standing in front outlet port has been investigated. First, a bond graph dynamic model developed, including throughout cushion design, characterized detail computational fluid-dynamic simulation. Following this, radial moveme...

BACKGROUND Evaluating shoes during sport-related movements may provide a better assessment of plantar loads associated with repetitive injury and provide more specific data for comparing shoe cushioning characteristics. HYPOTHESIS Accelerating, cutting, and jumping pressures will be higher than in straight running, differentiating regional shoe cushioning performance in sport-specific movemen...

Long-distance running is known to induce joint overloading and elevate cytokine levels, which are the hallmarks for a variety of running-related injuries. To address this, footwear systems incorporate cushioning midsoles to mitigate injurious mechanical loading. The aim of this study was to evaluate the effect of athlete body mass on the cushioning capacity of technical footwear. An artificial ...

Cereal Chem. 72(1):38-41 Physical properties of two biological cushioning materials made from dates were significantly higher than those of the wheat starch extrudates. wheat and corn starch extrudates were compared with those of commercial Both biological cushioning materials showed similar water absorption plastic foam cushioning material. Characteristics measured included isotherms at three ...

INTRODUCTION Repetitive loading of the musculoskeletal system is suggested to be involved in the underlying mechanism of the majority of running-related injuries (RRIs). Accordingly, heavier runners are assumed to be at a higher risk of RRI. The cushioning system of modern running shoes is expected to protect runners again high impact forces, and therefore, RRI. However, the role of shoe cushio...
