Extended-range electric vehicle is considered to be the ideal transition type for electric vehicle. The optimal operation curve control strategy was proposed for a 12 meter-long range extended electric bus. With exponential function inertia weight adjustment and local chaos substitution, an improved chaotic particle swarm optimization algorithm was applied to optimize the key parameters of energy management strategy. Based on MATLAB/Simulink, full vehicle model and corresponding control strategy were built. The simulation results with typical city driving cycles illustrate that, comparing with standard particle swarm optimization, the new algorithm can greatly improve the convergence speed and optimizing precision, and the optimal parameters can be obtained.

Hydrate based gas separation is a promising method for carbon dioxide capture. The purpose of thisstudy is to analyze hydrates formation and dissociation characters when gas mixture flows throughcooled silica gel. The additives mixture (THF/SDS) was used to saturate the silica gel partly, and gasmixture (CO2/H2) was injected into it to form hydrates. Magnetic resonance imaging (MRI) images wereobtained using fast spin echo multi-slice pulse sequence. Hydrates saturations were calculatedquantitatively using MRI data. The experimental results showed that the optimal initial solutionsaturation was 34.2% in this investigation. The gas component was analyzed to assess the separationefficiency. For hydrates dissociation processes at 1 atmospheric pressure, CO2 concentrations increasedobviously. Half of the six cycles showed that more than 85.00 mol% CO2 contained in the capture gas, andthe lowest CO2 concentration was 64.83 mol%. Hydrate blockages appeared frequently, which restrictedthe contact of gas and solution and caused the incomplete transformations of residual solution tohydrates. It was a key restricted factor for hydrate based CO2 capture.

The dynamic response and damage behavior of aluminum honeycomb sandwich panels (HC/SPs) subjected to hypervelocity impact by volcanic rock projectiles were investigated by hypervelocity impact tests and hydrocode simulations. The experiments were conducted using a two stage light gas gun and the results showed that the failure modes in HC/SPs subjected to hypervelocity impact by volcanic rock projectiles mainly took forms of front-face denting and circular perforation, honeycomb core collapsing and rapture, rear-face petalling and perforation etc. A 3D discrete configuration of the porous volcanic rock projectiles was set up. The hypervelocity impact behavior of the HC/SPs was investigated through hydrocode modeling, within a Lagrange-SPH coupling method in LS-DYNA solver. It was found that the dynamic response and failure modes in the HC/SPs were significantly influenced by the impact location and the impact velocity of the volcanic rock projectile.
