Abstract

The invention provides a packing box suspension shock absorber and a packing box utilizing the same. A product is connected with one point of a stiffening bar through a suspension rope, one end of the stiffening bar is connected with one side wall of a packing box where the product is packed, and the other end of the stiffening bar is connected with a top plate 6 of the packing box through suspension springs. When the packing box is impacted in horizontal direction or disturbed by an external vibration source, the disturbance energy is converted into gravitational potential energy through the suspension rope; when the frequency of the disturbance source is consistent with the natural frequency of the structure, the effective length of the suspension rope can be adjusted adaptively so that the natural frequency of the shock absorber is changed. When the packing box is disturbed or impacted in a vertical direction, the suspension springs have shock absorbing effect; when in resonance in the vertical direction, the length of the suspension springs change while the direction changes, the vertical component of the stiffness of the suspension springs changes, and the natural frequency of the system is changed, so that resonance is avoided, and displacement amplitude is limited.

Description

technical field [0001] The invention relates to the technical field of shock absorber devices, in particular to a packing box suspension shock absorber and its packing box, which are used for equipment or devices that have high vibration reduction requirements and cannot be squeezed at the same time, especially high-precision devices such as satellites. Instrument packing box design. Background technique [0002] At present, the general vibration reduction method is to install a linear spring between the equipment or the disturbance source as a vibration reduction device, but the linear spring damper has resonance in the low frequency band, and it cannot avoid the resonance area. At the same time, in order to avoid large displacement caused by the low frequency band, the spring stiffness is relatively large and the vibration damping effect is reduced; if a nonlinear damper is installed, due to the uncertainty of the nonlinear damping effect, and the nonlinear characteristics...
