  • Patent number: 12146179
    Abstract: Disclosed is a method for producing special oil OPO by way of microbial fermentation. The method comprises the following steps: inoculating microorganisms to an activating culture medium for shake cultivation treatment to obtain an activated culture; adding an organic matter into a minimal medium to obtain an optimized culture medium; inoculating the culture into the optimized culture medium for shake cultivation treatment to obtain a culture solution; carrying out centrifugal treatment on the culture solution, taking a precipitate, washing the precipitate and freeze-drying the precipitate, adding a hydrochloric acid solution to obtain a mixture; and adding an organic solvent into the mixture for extraction, and removing the solvent to obtain the OPO, wherein the microorganisms are Rhodococcus opacus PD630.

  • Publication number: 20240208289
    Abstract: The present invention discloses an active suspension vehicle and a control method controlling the same. Each wheel of the vehicle is equipped with a telescopically adjustable active actuator. The control method begins by constructing a load and deformation joint control matrix of the vehicle and measuring the current vehicle parameters; then determining vertical displacement excitation of wheels at a next moment, and pre-calculating passive responses of vehicle height, attitude, and wheel loads at the said next moment; determining the vehicle height, attitude, and feasible wheel load expectations at the said next moment, and inverse-calculating adjustment strokes of the suspension; finally, performing active suspension adjustment to chase the vehicle height, attitude, and feasible wheel load expectations in real-time.
