摘　　要：提出了一种新型杠杆型并联非线性能量阱的振动控制方法。基于谐波平衡法和伪弧长延伸法得到系统的幅频响应曲线。分析了杠杆型并联非线性能量阱的质量、非线性刚度以及悬挂位置对系统幅频响应的影响。对比研究了在孤立的环状共振响应消失后,杠杆型并联非线性能量阱与杠杆型单个非线性能量阱的吸振性能变化。仿真结果表明,在相同附加质量条件下,杠杆型并联非线性能量阱的吸振性能要优于杠杆型单个非线性能量阱。Here,a new vibration control method for lever-type parallel nonlinear energy trap was proposed.Firstly,the amplitude-frequency response curve of the system was obtained based on the harmonic balance method and pseudo-arc length extension method.Secondly,Effects of mass,nonlinear stiffness and suspension position of the trap on the amplitude-frequency response of the system were analyzed.Finally,vibration absorption performances of the lever-type parallel nonlinear energy trap and the lever-type single nonlinear energy trap were compared after the isolated ring resonance response disappears.The simulation results showed that the vibration absorption performance of lever-type parallel nonlinear energy trap is better than that of lever-type single nonlinear energy trap under the condition of the same added mass.
