Research and Analysis on Nonlinear Statics Behavior of Vibration Isolator with Geometric Anti-Spring with Different Translational Compressions
摘要
In order to realize low-frequency vibration isolation, the nonlinear structure of the geometric anti-spring (GAS) is investigated in this chapter. A dynamic model of the GAS is established so that the system can be described by the second-order differential equation boundary value problem. The differential equations are solved numerically using the shooting method and the bvp4c function. The effects of different translational compression on the mechanical properties, stiffness, and angular frequency properties of the GAS are considered. Simulation of the blade is carried out, and the stress distributions and nonlinear properties of the blades are analyzed and compared with the theoretical results.
