TARIFNAME BIR DINAMIK TITRESIM SÖNÜMLEYICI VE KULLANILDIGI ÇAMASIR MAKINESI Bu bulus, tahrik grubunda olusan yüksek genlikli titresimlerde çamasir makinesini dengeleyen bir dinamik titresim sönümleyiciye ve dinamik titresim sönümleyicinin kullanildigi bir çamasir makinesine iliskindir. Çamasir makinesi ve alt elemanlari üzerinde meydana gelen titresimler sakinilmasi gereken durumlarin basinda gelmektedir. Çamasir makinesi çalisir durumdayken tahrik grubu içeresinde meydana gelen rastlantisal dinamik yük dagilimlarina bagli olarak olusan titresim yüksek seviyelere ulasabilmektedir. DESCRIPTION A DYNAMIC VIBRATORY AND USED WASHING MACHINE This invention makes the washing machine at high amplitude vibrations occurring in the drive group. dynamic vibration damper and dynamic vibration pertains to a washing machine in which a damper is used. Vibrations on the washing machine and its sub-elements It is one of the situations that should be calmed down. The washing machine works random dynamic load occurring in the drive unit when in The vibration, which occurs depending on their distribution, can reach high levels.
Dolayisiyla, çamasir makinesi içerisindeki dengesizligin giderilmesi veya dengesizlik sebebi ile olusan yüksek genlikli titresimlerin sönümlenerek kontrol altina alinmasi gerekmektedir. Bu tip isten meyen titresimlerin uygun limitler dâhilinde tutulmasi gürültü ve kullanim ömrü parametrelerini dogrudan etkiledigi gibi çamasir makinesinin müsteri üzerindeki algisini olusturmaktadir. Therefore, removing the imbalance inside the washing machine or control by damping high amplitude vibrations caused by imbalance. must be underlined. Suitable limits for such undesirable vibrations keeping it within the scope directly affects the noise and lifetime parameters. It creates the perception of the washing machine on the customer.
Dinamik titresim sönümleyicileri, titresen mekanik yapilarin titresim genliklerini düsürerek kontrol altina almaya yarayan ve ana titresim sistemine monte edilerek kullanilan ikincil mekanik titresim sistemleridir. Bu sistemler basitçe, kütle, yay ve/Veya sönüm elemanindan olusurlar. Asil sistemin rezonans durumundan kaçinilmasi için çok uygundurlar. Tek serbestlik dereceli bir sisteme baglandiginda iki serbestlik dereceli bir sistem ortaya çikar. Tek serbestlik dereceli sistemin bir, olusan yeni sistemin iki tane dogal frekansi bulunmaktadir.Dynamic vibration dampers measure the vibration amplitudes of vibrating mechanical structures. It is used to control it by lowering it and it is mounted on the main vibration system. are the secondary mechanical vibration systems used. These systems are simply, mass, spring and/or damping element. From the resonance state of the principal system They are well suited to be avoided. A system with one degree of freedom When connected, a two-degree-of-freedom system emerges. one freedom The ordered system has one natural frequency and the new system has two natural frequencies.
Bu frekanslardan biri dinamik titresim sönümleyici kullanilmadan önceki sistemin dogal frekansindan daha büyük, digeri ise daha küçüktür. One of these frequencies is the system before the use of dynamic vibration damper. is greater than the natural frequency, and the other is smaller.
Dinamik titresim sönümleyicileri, dogal frekansa yakin bir tahrik ile uyarilan sistemlerdeki titresim problemlerinin çözülmesi için kullanilabilirler. Örnegin bir sisteme uygulanan tahrik frekansi, sistemin dogal frekanslarindan biri ile çakisiyorsa, bu çalisma frekansinda sistem rezonansa girer ve çok yüksek genlikli deplasmanlar gözlenir. Sisteme bir adet dinamik titresim sönümleyici eklendiginde ise; yüksek genlikli titresimler dinamik titresim sönümleyicide görülür. Böylelikle ana sistemin rezonansa girmesi önlenmis olur. Dynamic vibration dampers are excited by an excitation close to natural frequency. They can be used to solve vibration problems in systems. For example a the drive frequency applied to the system, with one of the natural frequencies of the system coincides, the system resonates at this operating frequency and causes very high amplitude displacements are observed. One dynamic vibration damper to the system when added; high amplitude vibrations in dynamic vibration damper is seen. Thus, resonance of the main system is prevented.
