Multi-point Layout Optimization of Tracked Vehicle Active Suspension
In order to achieve the optimization of active suspension between suspension performance and energy consumption for tracked vehicles,the multi-point layout optimization design of the active suspension based on the orthogonal test method is carried out.Firstly,a dynamic model of the tracked vehicle suspension system is established,and its rationality of the model is validated through road simulation test.Then,the orthogonal test of the suspension system is carried out,and the sensitivity of each sub-suspension on the suspension system per-formance under four typical road surfaces are analyzed.Finally,six layout schemes for active suspension actua-tors are devised.With the linear quadratic regulator(LQR)control,the dynamic model of active suspension is formulated.The influence law of each layout scheme on the suspension system's performance and the change law of energy consumption on typical road surface are analyzed.The results show that the balance between sus-pension performance and energy consumption can be achieved by optimizing the arrangement of active suspen-sion actuators for tracked vehicles.
