Abstract

The invention discloses a parallel self-resetting high-efficiency buffer braking machine, which comprises a connecting rod and two completely identical buffer braking mechanisms. The two buffer braking mechanisms are arranged symmetrically, and one end is connected through a connecting rod. The buffer brake mechanism includes the brake outer cylinder, the brake inner cylinder, the brake inner cylinder end cover seal ring ring seal, the first friction plate, two limit bolts, several disc springs and two second friction plates, etc. . The first friction plate and the two second friction plates are bolted together to achieve efficient energy dissipation through metal yielding, frictional heat generation, and viscous damping. The retreating inner cylinder and the retreating outer cylinder are nested together and filled with liquid, and the liquid flow hole formed by the gap plays the effect of hydraulic braking during retreating. Belleville springs provide restoring force to the device through elastic deformation of the material. The invention can be used to buffer huge impact loads and realize self-resetting, and has the advantages of good parallelism, smooth buffering and re-entry, stable retreating force, light weight, high buffering performance and large energy consumption.

Description

technical field [0001] The invention belongs to the field of buffer devices, in particular to a parallel self-resetting high-efficiency buffer brake. Background technique [0002] The parallel self-resetting high-efficiency buffer brake is a new type of buffer and shock absorbing device. This device can not only serve as the anti-recoil device of the current artillery, but also act as an earthquake buffer and anti-shock device. [0003] In the article "Seismic Analysis of Self-resetting Frictional Damping Steel Frame Buildings", Zhu Songye proposed a self-resetting frictional energy dissipator, which uses high-strength bolt connections and superelastic nickel-titanium alloys for frictional energy dissipation, but there is prestress The material memory alloy is expensive and the recovery force is greatly affected by temperature, the anchorage of the composite steel strand is relatively complicated, the stiffness degrades quickly after energy consumption, and the residual defo...
