| 研究了含分数阶项的二自由度悬架系统，利用改进的平均法、拉氏变换法、谐波平衡法和复频域法得到了简谐激励下系统响应的解析解，比较了解析解和数值解，二者逼近的精度很高，证明了解析解的准确性。分析了分数阶参数对悬架系统的动力学行为的影响，发现含分数阶微分悬架系统响应稳态幅值能够大幅降低，其动力学性能得到极大提高。 |
| 英文摘要: |
| The passive suspension system with fractional order derivative is studied. Analytic solutions of system under harmonic excitation eventually are obtained by improved averaging method, laplace transform method, harmonic balance method and complex frequency domain method. The analytic solutions prove to be accurate compared with numerical solutions. Effect of fractional order parameters on dynamical behavior is analyzed. The research indicates that, the steady state amplitude of passive suspension system with fractional order derivative could be significantly reduced and dynamical behavior can be greatly improved. |
