摘　　要：本文针对顶衬侧气袁爆破仿真,为了充分体现顶衬饰板在爆破过程中飭力学传递作用,在考虑顶衬饰件材料构成及各层力学性能特点的基础上,建立了基于各层实际力学性能的仿真结构模型,对各层材料参数模型选用适合的材抖本构模型进行表达。并进一步介绍了相关本构模型中失效参数的标定方法,从而形成了适用于侧乞丈爆破仿真的顶衬材料完整准确表达。最后通过仿真试验对标验证了方法的可行性与有效性。Aimed at interior trim fracture issue during airbag system deployment,based on material constitution and laminated mechanical properties of soft trim,a structure model for system simulation is set forth on parameter processing,and apply material constitutive model to each layer of material parameters.The approach of calibration is introduced of failure mode corresponding to constitutive model,an accurate module of laminatcd soft trim for curtain airbag deployment simulation is established,and correlation is then con ducted by way of simulation to ensure the effectiveness of the method.
