airbag. It is important that the airbag can only provide adequate protection with a seat belt together for a passenger. 4 Occupant safety simulation 4.1 Finiteelementmethod in general and the necessary components FiniteElementMethod (FEM) simulations
The main effect of lightning is the induced surge voltage within power networks. The paper deals with the assessment of electric potential generated during lightning. A time domain simulation using Finite Element Method was done, considering that the lightning current flows within a discharge channel with variable lengths (15–91 m) and impedances, having various peaks (2.5–40 kA). Both 8/20 μs and 5/320 μs lightning current wave shapes have been considered. The surge voltage waveforms were determined for each lightning current. The assessment of electric potential generated during lightning through phase wire, in soil and near underground power cable was done.
finite element technology was used in thermal calculation for the fluid in the storage tanks widely; however, the traditional finiteelementmethod might come into being numerical oscillation or distortion during the process of solving the big gradient
elasticity and plasticity.

With the knowledge of the advantageous characteristics of the cylindrical worm gear drives having arched profile in axial section and the conical worm gear drives having linear profile in axial section, a new geometric type conical worm gear drive has been designed and then manufactured, that is the conical worm gear drive having arched profile in axial section. Under same load and boundary conditions in case of the same geometric spiroid worm gear drives having arched profile and having linear profile in axial section we have done comparative finite element method analysis for evaluating the strains, deformations and stresses of this gear drives.
