Metal rubber laminated vibration isolator and method of manufacturing the same
By designing alternating layers of rubber with varying thickness and metal plates in the metal-rubber laminated vibration isolator, the pressure near the free surface and the central area of the rubber layer is basically the same, which solves the problem of uneven stress and improves the load-bearing capacity and durability of the vibration isolator.

AI Technical Summary
The existing metal-laminated rubber vibration isolators have the highest stress in the central area and uneven internal stress distribution, which makes the rubber layer prone to fatigue, thermal aging, and performance failure under long-term vibration.
A metal-rubber laminated vibration isolator is designed, wherein the thickness of the rubber layer in the central region is less than that in the edge region before molding. The rubber layers are alternately laminated and fixedly connected to a metal plate to form a flat plate structure. The metal plate is vulcanized by applying pressure to an arc surface mold and then welded to ensure that the pressure near the free surface of the rubber layer and the central region are basically the same.
This method achieves uniform stress distribution within the metal-laminated rubber vibration isolator, fully utilizes the compressive strength of the rubber layer, improves load-bearing capacity, and avoids fatigue and thermal aging issues in the central area.
