This invention discloses a double-layer clamp for aircraft piping with nonlinear vibration reduction function. The device includes an inner clamp, an outer clamp, clamp gaskets, fastening bolts, and fastening nuts. A certain constraint gap exists between the inner and outer clamps. Both the inner and outer clamps are assembled to the aircraft body using fastening bolts and nuts. The inner clamp consists of an inner clamp metal band and an inner clamp bushing; the outer clamp also consists of an outer clamp metal band and an outer clamp bushing. Both the inner and outer clamp bushings are made of nitrile rubber-organic small molecule hybrid composite material, exhibiting excellent damping performance. This invention utilizes the outer clamp to provide nonlinear constraint stiffness and nonlinear constraint damping to achieve nonlinear vibration reduction, enabling wide-frequency vibration reduction and effectively improving the vibration reduction performance of traditional single-layer clamps. This device is easy to manufacture and install, employs a nonlinear passive vibration control strategy, and achieves high efficiency at low cost.

The present invention discloses a frame system with switchable connection modes between a frame and a front axle, including a frame, wherein the lower part of the front end of the frame is connected to the front axle via a leaf spring; the frame comprises two longitudinal beams arranged in parallel, and a group of switching components are respectively arranged at the left and right front ends of the two longitudinal beams, and the switching components are used to switch the connection mode between the frame and the front axle between an elastic connection and a rigid connection. The present invention also discloses a method for switching the connection mode between the frame and the front axle. The frame of the present invention has two connection modes, namely a rigid connection and an elastic connection, and the elastic connection is used when the industrial vehicle is traveling at high speed, and has a good vibration reduction function. The industrial vehicle switches to a rigid connection when it reaches the working area, and the industrial vehicle has good impact resistance. The frame system with switchable connection modes between the frame and the front axle of the present invention saves an additional transport vehicle for transporting engineering vehicles, and saves costs.
