Abstract The effective solution to avoid machinery damage caused by resonance has been perplexing the field of engineering as a core research direction since the resonance phenomenon was discovered by Euler in 1750. Numerous attempts have been performed to reduce the influence of resonance since the earlier of last century. by introducing a nonlinear structure or a closed-loop control... https://www.balboasurfandsstylers.shop/product-category/little-boys-fleece-shorts/
