In downhole drilling systems. self-excited torsional vibrations caused by the bit-rock interactions can affect the drilling process and lead to the premature failure of components. Especially self-excited oscillations of higher-order modes lead to critical dynamic loads. The slim drill string design and the naturally limited drilled borehole diameter limit the installation space. https://safeersappliancers.shop/product-category/aeg-dvk6980hb-wall-mounted-hood/
