Study on the Application of Hydrophobic Microporous Materials in Vehicle Suspension Systems
In order to improve the ride comfort of automotive suspension,a suspension spring made of hydrophobic microporous material was proposed.Firstly,the preparation of hydrophobic microporous materials for low pressure molecular spring suspen-sions is introduced,and its working mechanism is explained using the Laplace capillary principle.Based on the principle of hy-drostatics,a stiffness model of the passive suspension is established,and the main resonance response of the nonlinear dynamic system is solved using the averaging method.The performance of the passive suspension is simulated using MATLAB Simulink,and its ride comfort is evaluated based on the weighted root mean square acceleration.The research results show that the natural frequency,suspension deflection,and weighted acceleration of the new suspension meet the design objectives.Finally,by build-ing a test platform,the effectiveness of the proposed suspension system is further verified,indicating that the new suspension has strong engineering application value.
