    摘要： Proposed is a rubber bush type vibration damping device for a vehicle, which solves the problem of vibration increase which may occur in the natural frequency of the vibration damping device by changing the shapes of an inner coupling part or an outer coupling part and by using difference in the lengths of rubber insulators due to the changing of the shapes thereof. The vibration damping device includes an inner coupling part, an outer coupling part, and a plurality of rubber insulators having have different natural frequency.

    摘要： The present invention of damping segmental ring structure for subway tunnels built in grim environments of deformable ground can mitigate the stress-concentration of the tunnel lining structures. The deformable ground can be caused by differential settlement or high-intensity earthquakes. Embodiments of the invention have self-adjustment features and forms for deformation and rotation, which comprise one adapter in the middle, two transitional grooved segmental structures, and an internal steel tube. All three forms comprised 3 or 4 pieces with the same features so they can be easily installed, transported and erected on sites and bolts are used to bolt them together to form an integrity structure with damping characteristics. The damper placed in the middle comprises two loading plates that form the shell of the damper, the internal core of the damper which includes interbedded installed rubber pads and steel plates within the loading plates and spring systems that compress the internal core. The springs are locked to the loading plates using locking clamps and the loading plates are bolted to the transitional grooved segmental ring structures, and the transitional grooved segmental ring structures are bolted themselves in the circumferential direction to form a ring structure and bolted with the regular segmental ring structures in the longitudinal direction. The internal steel tube is concentric with the damper but has a smaller diameter so it can support the damper by fastening the counter-reaction bolts installed in the bent-up flanges of each piece. Waterproof anti-slippery rubber pads are placed in all interfaces between the damper, and the transitional segmental ring structure, the regular segmental ring structure and the internal steel tube. The invention of the damping segmental ring structure has self-adjustment capabilities for deformation and rotation whereas the stiffness remains sufficient to resist soil and groundwater pressure. The invented damping segmental ring structure can be manufactured in factories that manufacture the regular segmental ring structure and can be shipped to and installed on-site using the same equipment that installs the regular segmental ring structure. The internal steel tube provides double-safety for the stiffness of the damper and the supports can be adjusted during tunnel operations.

    摘要： A liquid composite spring for vehicles includes: a core shaft; an outer sleeve arranged on an upper portion of the core shaft, the upper portion of the core shaft being located inside the outer sleeve while the lower portion of the core shaft being located outside the outer sleeve; an upper liquid chamber formed in an upper portion of the outer sleeve, a lower end of the upper liquid chamber being connected to a top of the core shaft; and a lower liquid chamber formed in a lower portion of outer sleeve, the lower liquid chamber and the upper liquid chamber being connected with each other through a metal-rubber main spring. At least one flow channel body is provided in the metal-rubber main spring, so that liquid in the upper liquid chamber and liquid in the lower liquid chamber are communicated with each other through the flow channel body.

    摘要： A shock-absorbing or vibration-absorbing assembly includes a metal base and an elastic shock-absorbing or vibration-absorbing material secured to the metal base. A top surface of the metal base has at least one orifice extending from the top surface to at least one hollow chamber beneath the top surface. The hollow chamber occupies a planar area of the metal base parallel to the top surface that is larger than a planar area of the metal base that is occupied by the orifice at the top surface. The elastic material is secured to the metal base by the elastic material filling the orifice and the hollow chamber of the metal base and the elastic material filling a region above the top surface of the metal base that has a cross-sectional area parallel to the top surface of the metal base that is larger than the planar area of the metal base that is occupied by the orifice at the top surface of the metal base. The elastic material is secured to the metal base by placing the metal base against a mold having a hollow space to be filled with the elastic material. The elastic material is injected into the hollow chamber and orifice of the metal base and into the hollow space of the mold. The mold is removed from the metal base, so that the elastic material is secured to the metal base by the elastic material filling the orifice and the hollow chamber of the metal base and the elastic material filling a region above the top surface of the metal base that corresponds to the hollow space of the mold.
