How material, manufacturing process and design influence vibrational performance?5 answersMaterial properties, manufacturing processes, and design choices significantly impact vibrational performance. For instance, composite materials like PA66GF35 exhibit anisotropic behavior due to the orientation of reinforcing fibers during injection molding, affecting vibration modes and mechanical properties. Vibration treatment efficiency is influenced by factors such as abrasive granule characteristics, processed part hardness, and surface shape, highlighting the importance of material interactions in vibration processing. In aerospace industries, advanced engineering materials with superior properties pose challenges in traditional machining due to high wear resistance and low thermal conductivity, leading to the adoption of nontraditional methods like vibration-assisted machining to enhance material removal processes and improve product quality. Additionally, additive manufacturing techniques incorporating fully encapsulated cavities filled with powder aim to enhance damping properties without compromising component performance. Introducing mechanical vibration during additive manufacturing processes refines grain structures, reduces defects, and minimizes residual stresses, ultimately improving the performance of manufactured parts.
What are the effect of Whole body vibration on calf muscle?5 answersWhole body vibration (WBV) has been shown to have positive effects on calf muscles. WBV training programs have been reported to improve knee extensor muscle (KE) strength, including the calf muscles. WBV at specific frequencies and postures can lead to increased muscle contraction in the calf muscles, such as the Gastrocnemius Lateralis (GL), Soleus (SOL), and Tibialis Anterior (TA). WBV training can also increase isometric plantar flexor strength at multiple joint angles, including the calf muscles. Additionally, WBV exposure has been found to significantly increase muscle activity in the calf muscles, such as the Vastus Lateralis (VL), Biceps Femoris (BF), and Gastrocnemius (GS). Therefore, WBV can have positive effects on calf muscle strength, activation, and neuromuscular response.
How does humidity affect on human performence?4 answersHumidity has been found to have an impact on human performance. In hot and humid conditions, the cognitive performance of individuals working in such environments can be affected. The electrocardiogram (ECG) data analysis showed that the temporal index pNN50 of HRV time domain indices can act as a biomarker for cognitive performance. Additionally, when exercising or working under severe heat stress, the absolute humidity (water content in air) is more important than air temperature alone. Elevated humidity, along with high air temperature, increases physiological and perceptual strain, impairs endurance exercise performance, and causes higher heart rate, sweat rate, and thermal perceptions. Furthermore, in hot and humid conditions, both elite para-athletes and able-bodied athletes demonstrated similar performance decrements during exercise, while para-athletes had lower elevations in gastrointestinal temperature compared to able-bodied athletes. These findings suggest that personalized heat mitigation plans should be developed based on individual thermal testing for both para-athletes and able-bodied athletes.
How does vibration affect on performence?3 answersVibration can have various effects on performance. In the context of mechanical systems, excessive vibration can reduce the smoothness and service life of components, affect system stability, and produce noise. In the context of athletic performance, vibration exercise has been used for athletic development, injury rehabilitation, and improving explosive power and flexibility. However, its effects on strength measures, sprinting, and as a recovery strategy are less convincing. In the context of cognitive performance, exposure to vehicle vibration has been found to disrupt sustained attention and information processing speed. In the context of non-athletic individuals, vibration training has been shown to improve strength, speed, agility, and testosterone hormone levels, potentially through increased muscle contraction speed and activation of motor neurons. Overall, the effects of vibration on performance depend on the specific context and individual factors.
Does vibration of the soleus muscle at 150Hz lead to increased muscle strength?5 answersVibration of the soleus muscle at 150Hz does not lead to increased muscle strength. The studies found that prolonged vibratory stimulation did not result in changes in the EMG of the short-latency stretch reflexes (SLR) of the soleus muscle. However, applying vibration with parameters of frequency: 100Hz and amplitude: 1.6mm did enhance the positive slope and threshold of the H-reflex recruitment curve, leading to increased recruitment of fast and slow motor neurons. Another study showed that vibration intervention during immobilization did not attenuate the negative adaptations induced by immobilization, as there were no changes in the maximal M-wave (Mmax) and H-reflex (Hmax) responses of the soleus muscle. Therefore, while vibration therapy may have some effects on motor neuron recruitment, it does not appear to directly increase muscle strength at a frequency of 150Hz.
How are insects affected by vibration?5 answersInsects can be affected by vibrations in various ways. Some insects, such as aphids, can be repelled by non-specific substrate-borne vibrations, causing them to leave the plant. Other insects, like those in the order Coleoptera, demonstrate immobility in response to vibrations, which can serve as a defense mechanism against predators or conspecifics. Insects have specialized receptor organs, such as scolopidial sensory organs, that allow them to detect and process vibratory signals. Vibrations play a significant role in insect communication, with many insects using vibrations for mate finding and other forms of communication. Overall, vibrations can have both positive and negative effects on insects, influencing their behavior, communication, and interactions with their environment.
