| Abstract: | On the base of current studies,some optimum criteria on deployment performance of airbags are proposed. Finite element models for airbags with different folding pattern are set up with LSCD*3]DYNA software. Combining with static deployment tests and video processing technologies,the deployment characteristics of a new type of airbag with a typical folding pattern are analyzed. Based on the results of simulation,a new folding pattern for enhancing the effectiveness of occupant protection is designed. The test result proves that the new folding pattern has a good deployment characteristic. |
