Genetic algorithm (GA) was used to solve the multi-objective non-linear optimization design of a hydro-pneumatic spring. To develop the genetic algorithm of the optimization of hydro-pneumatic spring, a weighted sum was used to normalize the four objectives of ride comfort, suspension stroke, road holding and road friendliness with fixed weight, linear fitness scaling was used to enhance the global...
In this paper, 6 degrees of freedom vibration model of hoist cage excited by steelwork faults was established first. Then horizontal and vertical vibration characteristics under local faults and whole faults were simulated through MATLAB, based on which a wavelet singularity method was proposed to process the vibration to determine the position and seriousness of the steelwork faults. Finally, simulation...
The paper introduces the treatment of recirculating water from refinery plant with grid filtration to remove suspended solid to decrease the turbidity in the water. The emphasis is on the determination of grid filtration quantity, the design of grid filtration, the determination of back washing. With the operation of grid filtration, the water quality of outlet is improved a lot, which shows that...
