前言橡胶制品的有限元分析至少能在以下主要范围内提供精确的资料:1,刚度予测;2),应力分析;3),疲劳寿命予测;4,外力作用下材料的内部生热;5,硫化状态的分析。有限元分析过去已用于橡胶制品,从而大大节省了设计、试验和生产方面的时间和费用。但是,在所有的有限元分析中必须考虑到作为工程材料的橡胶所具有的特点。诸如1)通常是大变形;2)材料的应力—应变规律呈非线性;3)材料有粘弹性;4)泊松比近似为0.5;5)通常是三维受力。 Preface The finite element analysis of rubber products provides accurate data, at least in the following main areas: 1. Stiffness prediction; 2.) Stress analysis; 3.) Fatigue life prediction; 4. Internal heat generation of materials under external forces; 5, the analysis of the curing state. Finite element analysis has been used in rubber products in the past, saving significant time and expense in design, testing and production. However, the characteristics of rubber as an engineering material must be considered in all FEA analyzes. Such as 1) is usually a large deformation; 2) the stress-strain law of the material is nonlinear; 3) the material is viscoelastic; 4) the Poisson’s ratio is approximately 0.5;
