Abstract

Problemler: Basit bir yapım şekli olan ve tetikteme fonksiyonu ve başka fonksiyonlar da temin eden, hem negatif rijidite hem friksiyon azaltma fonksiyonları arzedebilen negatif rijidite tertibatının temin edilmesi. Problemlerin Çözülme Yolları: Negatif rijidite tertibatı aşağıdaki kısımları içermektedir: içbükey şekilde eğri yüzü olan bir kanala sahip olan üst eleman; eğriliği, üst elemanın içbükey şekilde eğri yüzü olan kanalının eğriliğinden daha küçük olan dışbükey şekilde eğri bir üst yüzeye sahip olan yarı-silindirik alt eleman; ve üst elemanın içbükey şekilde eğri yüzü olan kanalı ile aynı eğriliği olan dışbükey şekilde eğri bir üst yüzeye ve alt elemanın dışbükey şekilde eğri üst yüzeyi ile aynı eğriliği olan içbükey şekilde eğri bir alt yüzeye sahip olan kaydırma elemanı; burada, kaydırma elemanının dışbükey şekilde eğri üst yüzeyi üst elemanının içbükey şekilde eğri yüzü olan kanalı ile temas içinde olduğunda ve kaydırma elemanının içbükey şekilde eğri alt yüzeyi alt elemanının dışbükey şekilde eğri üst yüzeyi ile temas içinde olduğunda, kaydırma elemanı, üst eleman ile ilişkisi içinde dönerken alt elemanının üst yüzeyi üzerinde kaymakta, böylece, negatif rijidite tertibatı negatif rijidite ve friksiyon azaltma temin etmektedir. Negatif rijidite tertibatı ve eski haline getirme fonksiyonu olan lamine kauçuğun bir yapıya monte edilmesi, sismik yalıtım etkisi ayarlanabilen ve depremden, vs. uyarımdan sonra orjinal konumuna kolaylıkla geri dönen bir sismik yalıtım yapısını gerçekleştirmektedir.Problems: Providing negative rigidity device, which is of simple construction and can exhibit both negative rigidity and friction reduction functions, which also provides trigger function and other functions. Ways of Solving Problems: The negative rigidity assembly includes the following parts: the upper member having a concave curved face channel; semi-cylindrical lower element having a convexly curved upper surface, the curvature of which is less than the curvature of the concave-faced channel of the upper element; and the slide member having a convexly curved upper surface having the same curvature as the concavely curved channel of the upper member and a concavely curved lower surface having the same curvature as the convexly curved upper surface of the lower member; wherein the convexly curved upper surface of the slider element is in contact with the concavely curved groove of the upper element, and the concavely curved lower surface of the slider element is in contact with the convexly curved upper surface of the lower element, while the slider rotates in relation to the upper element. slides on the upper surface of its lower member, thereby providing negative rigidity and friction reduction. Installing the laminated rubber with negative rigidity device and restoring function in a structure, the seismic insulation effect can be adjusted and protected from earthquake, etc. It realizes a seismic isolation structure that easily returns to its original position after excitation.
