Abstract

In order to solve the problem of performance deterioration and ensure structural reliability of the electromechanical suspension of high-speed tracked vehicles in high-frequency zone

the stiffness characteristics of the electromechanical suspension based on the torsion bar are analyzed

the complex motion relationship of the suspension rod system is solved

the equivalent inertia mass of the electric actuator is calculated

and a two-degree-of-freedom electromechanical suspension model considering inertia mass and load wheel damping is established. We quantitatively analyze the adverse impact of inertia mass on suspension performance

and obtain the frequency domain distribution interval and power spectral density distribution interval of inertia force affecting suspension's ride comfort and component reliability. According to the frequency domain distribution of suspens

ion inertia force and the amplitude frequency characteristics of the suspension's dynamic deflection

the measures of vibration filtering and buffering are put forward

and a suspension model with the vibration filtering buffer is established. The simulation and test results show that vibration filtering and buffering can effectively reduce the influence of inertial mass. Under the driving condition of 40km/h on class D Road

the root mean square value of the original inertial force is reduced from 2143N to 175N

and the root mean square value of sprung mass acceleration is reduced from 3.5108m/s

to 1.2682m/s

. The bench test shows that the gear ring stress is greatly attenuated after the vibration filtering and buffering measures are adopted

and the maximum value is reduced from 519.9MPa to 110.1MPa. Through simulation and test

it is verified that the measures of vibration filtering and buffering can improve the performance of the electromechanical suspension and help to solve the problem of performance deterioration in the high frequency zone caused by inertial mass.

A model reference multi-mode switch controller is designed to improve the adaptability of parallel composite electromagnetic suspension to different road conditions， in which the characteristics of different working modes are considered， and the switching index， threshold value and corresponding control parameters are determined for the purpose of improving ride comfort. A multi-mode switching control system is designed based on Stateflow for the discrete character of switching instruction and the continuous character of state change of suspension system. The performance of model reference multi-mode switch controller are simulated and tested. The results show that the model reference multi-mode switch controller can be used to effectively implement the switching between working modes of parallel composite electromagnetic suspension， which improves its adaptability to different road conditions， and effectively balances the contradiction between vibration reduction and energy-regeneration.
