Abstract With its complex nonlinear dynamic behavior, the tristable system has shown excellent performance in areas such as energy harvesting and vibration suppression, attracted a lot of attention. In this paper, an asymmetric design is proposed to improve suppression efficiency sinks (NESs) for first time. The NES (ATNES) composed pair oblique springs vertical spring. Then, three stable states, symmetric asymmetric, can be achieved by adjustment distance stiffness asymmetry springs. governing equations linear oscillator (LO) coupled with ATNES are derived. approximate analytical solution obtained harmonic balance method (HBM) verified numerically. types compared. results show that reduction through comparing chaotic motion between steady states. addition, compared symmetrical (TNES), effectively control smaller structural vibrations. other words, solve threshold problem TNES failure weak excitation. Therefore, paper reveals mechanism ATNES, provides pathway expand effective excitation amplitude range NES.
