Based on the analysis of the bus system dynamics, the five degrees of freedom bus system dynamics equation has been established, using vehicle speed and front wheel angle as input, and sideslip angle, yaw rate, the sprung mass roll angle, the sprung mass roll angular speed, lateral load transfer capacity front axle and rear lateral load transfer capacity as output. According to the linear control...
The two-stage integral sorption data for water vapour in a glassy poly(2-hydroxyethyl methacrylate) (PHEMA) membrane are analysed by the variable-surface concentration model, the diffusion-relaxation model, and the diffusion-reaction model. Satisfactory fitting of the data and similar kinetic and equilibrium parameters are obtained using these models. The diffusion coefficient for water is about...
The sorption and desorption of water vapour into and from a hydrophilic poly(2-hydroxyethyl methacrylate) (PHEMA) membrane were examined with the gravimetric method in an integral manner at 37 o C. The sorption isotherm of water in PHEMA at 37 o C followed Henry's law at lower activities and Flory-Huggins type sorption at higher activities. The water content which leads to a glass-rubber...
Novel temperature-sensitive membranes have been synthesized by grafting poly(N-isopropyacrylamide) (poly(NIPAAm)) onto a poly(vinyl alcohol) (PVA) backbone using hydrogen peroxide-ferrous ion as initiator. Due to the grafting of poly(NIPAAm), the hydrophilic/hydrophobic balance and the polarity of the pendent groups within the membranes are modified. Significant temperature sensitivity of the grafted...
