The ability of current modeling and simulation tools to accurately predict a building fire of practical size and duration is at issue. Modeling is challenged by computational cost, fidelity of assumed physics, and correct knowledge of initial and boundary conditions. A series of simulations has been conducted to compare with experiments for a fuel fire in a facility. The purpose of the study was to understand the importance of simulation parameters. The test geometry is sufficiently large and the fire of long enough duration to present a challenge to model in detail. Several computational parameters have been varied at magnitudes consistent with the uncertainty in the parameter to determine the parametric sensitivities. The predicted heat flux inside the facility was sensitive to varying degrees to the parameters selected for the study, with those related to the fuel source being the most important physical parameters.

D Model

The mechanical design of computerized glove machine was traditional. It was not only lack of theoretical analysis of key institutions, but running stability needed to be improved. We analyzed the impact of the needle and cams which was based on the computerized glove machine’s knitting theory and key process points. On the basis of SolidWorks, 3-D model of computerized glove machine’s knitting element was created; We imported the 3-D model to ANSYS/LS-DYNA system and realized the motion simulation of needle and cams. As a result, we got the curves of needle’s displacement, velocity and acceleration. According to the simulation parameters of needle’s movement, the knitting element was optimized design. The result reveals that acceleration reaches a maximum of 0.63×105m/s2 when knitting time is 0.052ms. It reduces nearly 16% compare to the result before design optimization of knitting element. The smooth of computerized glove machine is being improved significantly.
