为了实现对惰性元件的控制，建立更符合实际的可控惰性元件模型，本文设计了一种可控惰性元件，并对其非线性因素进行了分析。分析了可控惰性发动机的理想模型、常规非线性模型和标定后的非线性模型，研究了流体的可压缩性。在试验台上对可控惰性发动机样机进行了试验，并对摩擦力进行了辨识。分析了气液混合和纯流体两种情况下可控惰性气体中流体的体积弹性系数。建立了具有非线性可控惯性系的悬架动力学模型。并对不同非线性模型的悬架性能进行了分析。结果表明，标定后的非线性模型能较好地反映惯性力矩。混合空气对悬架性能有严重的负面影响，非线性因素会对控制效果产生负面影响。
To realize the control of the inerter and establish a more realistic model of the controllable inerter, this paper designs a controllable inerter and analyzes its nonlinear factors. The ideal model, conventional nonlinear model, and calibrated nonlinear model of the controllable inerter are analyzed and the compressibility of fluid is studied. The prototype of a controllable inerter is tested on the bench and the friction force is identified. The bulk modulus of the fluid in controllable inerter in the fluid-air mixture condition and the pure fluid condition are analyzed. A suspension kinetics model with nonlinear controllable inerter is established. And the performances of the suspension with different nonlinear models are analyzed. The result shows that the inerter force can be reflected through the calibrated nonlinear model. The mixed air has a serious negative effect on the suspension performance and the nonlinear factors will take a negative effect on the control results.
