AI Technical Summary
Existing dynamic vibration absorbers lack robustness in both the frequency and force domains, especially purely nonlinear vibration absorbers, which exhibit unsatisfactory robustness in the force domain, thus limiting their application in engineering.
A passive dynamic vibration absorber with composite nonlinear characteristics was designed. Through the parallel arrangement of the base and top cover, vertical column and guide rail, combined with mass components, multi-layer springs and elastic limiting ropes, it can achieve vibration absorption capability with wide frequency band and wide force range and prevent collision between mass components.
While maintaining frequency domain robustness, the effective force domain of the vibration absorber is significantly broadened, improving its stability and vibration absorption effect under external excitation.
