    Abstract
  • In order to reasonably match the pre-charge pressure, maximum working pressure and volume of accumulator for active suspension without external energy supply based on LQG(linear quadratic Gaussian) control, twice standard deviation of ideal control force was proposed as the maximum force output of active suspension to meet 95.4% of work demand, and the parameters of reclaiming energy/active cylinder were taken into account to ascertain the ideal working pressure of accumulator. To make the pressure fluctuation in accumulator less than 5%, the pre-charge pressure and maximum working pressure of accumulator were matched. The energy flow equations between active suspension and accumulator were deduced. Under 2 kW load, the varying volume's dynamic simulation of accumulator was carried out. Computation result shows that the ideal working pressure of accumulator is 23.008 MPa, and the quadratic performance index of the suspension increases 5.21% compared with the ideal state. Accumulator's pre-charge pressure, maximum working pressure and volume are 11.108 MPa, 23.583 MPa and 2.5 L respectively, and the maximum pressure fluctuation in accumulator is 1.03% when the active suspension without external energy supply based on LQG control works steadily. So the demand with low manufacture cost, good suspension performance and high energy reclaiming efficiency for the active suspension is achieved.
