Abstract

The invention discloses a low-rigidity high-mass suspension method. An Euler spring and an air bag type low-rigidity suspension device are connected in parallel to form a parallel structure. One end of the parallel structure is fixed, and the other end of the parallel structure horizontally suspends a carrying platform. Most of the mass of the carrying platform is borne by the Euler spring. The carrying platform is used for carrying weights. The mass of the weights is changed continuously. The dynamic changing mass of the weights and the other small part of the mass of the carrying platform are borne by the air bag type low-rigidity suspension device. Through the low-rigidity high-mass suspension method, the defect that the Euler spring can only work at constant load is overcome, and the problem that an existing air bag type low-rigidity suspension device cannot bear a high-mass carrying platform is solved. A new solution is provided for low-rigidity high-mass suspension.

Description

technical field [0001] The invention belongs to the field of vibration measuring instruments, in particular to a low-rigidity large-mass suspension method. Background technique [0002] When the Euler spring is in the critical state of Euler buckling, the axial stiffness decreases sharply, and it can bear a large load. This physical characteristic determines that the Euler spring can only carry a certain value. For the loading platform that is undergoing experimental operation, the mass will continue to change, and the Euler spring cannot cope with the loading platform whose mass changes dynamically, which requires a new low-stiffness large-mass suspension method to solve this problem. [0003] Airbag-type low-stiffness suspension has the advantages of high power-to-weight ratio, low stiffness, no pollution, and low cost, and is more suitable for applications in the fields of aerospace and precision testing instruments. The pressure inside the airbag in the airbag-type low...
