Dynamic Modeling and Characteristic Analysis of Inertial Capacity Hydropneumatic Suspension with Fractional-order Terms
In order to improve the accuracy of the inertial hydraulic suspension model for a wheeled armored vehicle,the damping force generated by moving parts in the inertial hydraulic suspension was considered,and the dynamic modeling of the inertial hydraulic suspension was carried out to verify the correctness of the model.Additionally,fractional-order operators were introduced to build a simplified suspension model with fractional-order terms for simulation using MATLAB/Simulink software.To find the optimal fractional-order of the simulation model,a comprehensive performance evaluation index function was established to determine the optimal order.By organizing and analyzing the simulation results,it is concluded that the fractional-order model has higher simulation accuracy compared to traditional integer-order models,providing a reference for improving the accuracy of simulation research on inertial hydraulic suspension.
