摘要
运用基于核函数变换的多元累加模型和偏最小二乘回归方法,建立了磁流变阻尼器在冲击载荷下的冲击力和冲击加速度的峰值关于冲击质量、冲击速度和输入电流三个影响因素的线性模型。模型的回归数据和预测数据与实验数据的比较结果证明,该动态模型不仅有较高的回归精度,而且有较好的稳健性。
Exerting multivariate additive model based on kernel function and partial least-squares regression, the linear model of dynamic response peak values, such as impact force and impact acceleration of magneto-rheological damper, subject to impact mass,impact velocity and input current was established. A comparison of regressive datum and predictive datum of established model with testing datum demonstrates the dynamic model possesses higher regression precision, and beares better robustness.
