Representative work: This study proposes a novel viscoelastic bio-inspired multi-dimensional vibration isolation device (VBM-VI). The viscoelastic (VE) damper and the limb-like-structure (LLS) are first installed into the vibration device to make it simultaneously reveal excellent vibration isolation performance at three directions. First, the dynamic equations of the proposed device are established, and the significant coupling nonlinear characteristics caused by material and geometric factor together are discussed. Then, the harmonic balance method (HBM) is used to solve the nonlinear dynamic equation, and the geometrical parameters of the VE damper and LLS device are studied to assess the influence of couplin The nonlinear characteristic of vibration control systems has attracted increasing attention for its advantage in improving structural performance. In this paper, a new type of viscoelastic damping limb-like-structure (VE-LLS) device is proposed by combing the viscoelastic (VE) damper and limb-like-structure (LLS) together, which possesses coupling nonlinearity characteristic caused by geometric and material factors, as well as a remarkable advantage in improving the control performance. First, to explore the nonlinear geometrical effects on the static stiffness of the VE-LLS device, a formula is derived from static stiffness, and the results are discussed. Second, dynamic analysis is perfor
