气垫盘是薄气垫装置的关键性元件,我们在试验研究中需要了解气垫盘在工作时气垫胶囊的受力情况、承载能力以及它的变形规律,以便正确设计和选择气囊及有关元件。橡胶囊属于高弹性体,它的应力和变形的关系不适用于虎克定律(除应力很小时除外,见图1),即不能用古典弹性理论来研究气垫胶囊的载荷与变形的函数关系。比较简便的方法是通过试验进行实际的观测。 Air cushion is a key component of the thin air cushion device. In the experimental study, we need to understand the force, the carrying capacity and the deformation law of the air cushion capsule when working, so that the airbag and related components can be correctly designed and selected. The rubber capsule belongs to highly elastic body. The relationship between stress and deformation is not suitable for Hooke’s law (except when the stress is very small, see Figure 1). That is to say, the classical elastic theory can not be used to study the relationship between the load and the deformation of the air-cushion capsule. The simplest way is to experimentally conduct the actual observations.
