This paper introduces nonlinearity into bilinear springs and proposes an efficient asymmetrical nonlinear frequency converter (NC) that has a non-reciprocal transmission, which cascades a nonlinear spring and a rope. To solve the vibration equations of both NC and the conventional NES, the Runge-Kutta method is utilized. A comparison is conducted between the amplitude attenuation rates of the NC and the conventional NES. The rate of energy dissipation is indicated by analyzing the remaining energy. According to numerical analysis results, NC has a better performance in suppressing vibration than the conventional NES within a certain range. The energy dissipation rate is higher under a wide initial condition. In addition, NC can cause energy to shift from low-frequency regions to high-frequency regions with wide frequency bands. NC has a broader frequency range and a wider range of applications. This research offers a new approach and strategy for exploring effective devices for damping vibrations.

具有本质上非线性转换器的非线性隔振器


本文将非线性引入双线性弹簧，并提出了一种具有非互易传动的高效非对称非线性变频器（NC），它级联了非线性弹簧和绳索。为了求解 NC 和传统 NES 的振动方程，采用了龙格-库塔方法。对 NC 和传统 NES 的振幅衰减率进行了比较。通过分析剩余能量来指示能量耗散率。根据数值分析结果，在一定范围内，NC比传统NES具有更好的抑制振动的性能。在较宽的初始条件下能量耗散率较高。此外，NC可以导致能量从低频区域转移到具有宽频带的高频区域。 NC的频率范围更广，应用范围更广。这项研究为探索有效的减振装置提供了一种新的方法和策略。
