How to generate finite element mesh for folded airbags
نویسنده
چکیده
This work presents a novel algorithm for generating a geometric mesh of an airbag after a series of folds are defined on it, for use in crash simulations. The process of airbag folding is simulated as a series of geometric transformations to the airbag mesh, which is modeled as a stack of connected planar layers. Along with these transformations, optimization techniques are used to minimise change in the geometry and the area of the airbag post inflation. The results from this approach are compared with other commercial airbag folding software, and it is observed that the algorithm is effective in ensuring minimum change in the area and geometry of the airbag during the folding process. The current paper is a sequel to [3] which shows some initial results of the folding process.

A periodic folded piezoelectric beam for efficient vibration energy harvesting
Periodic piezoelectric beams have been used for broadband vibration energy harvesting in recent years. In this paper, a periodic folded piezoelectric beam (PFPB) is introduced. The PFPB has special features that distinguish it from other periodic piezoelectric beams. The Adomian decomposition method (ADM) is used to calculate the first two band gaps andtwelve natural frequencies of the PF...

متن کاملFast Finite Element Method Using Multi-Step Mesh Process
This paper introduces a new method for accelerating current sluggish FEM and improving memory demand in FEM problems with high node resolution or bulky structures. Like most of the numerical methods, FEM results to a matrix equation which normally has huge dimension. Breaking the main matrix equation into several smaller size matrices, the solving procedure can be accelerated. For implementing ...
