MarshMellow Introduction, Construction and Function橡胶弹簧介绍、构造以及功能;What is a Marsh Mellow?? 橡胶弹簧是什么？ Rubber cylinder橡胶柱 Fabric reinforced纤维加固 Compression Spring压缩弹簧 Vibration Isolator隔振器;Developed in 1973开发于1973年 Looking for a “spring” with similar characteristics to an air spring, but without requiring air 需求是：性能类似于空气弹簧但是不需要压缩空气 Why the name MarshMellow? 为什么叫MarshMellow Developed by Firestone engineer, Jerry Marsh 开发者是凡士通工程师， Jerry Marsh ;Unique elements of design flexibility特殊的组成 Solid rubber core material 实心橡胶芯 Hollow center中空中心 End configuration 端面形状可选 Fabric reinforced plies 纤维增强层 ;Application dependent 基于应用 Vibration Isolation Compound (all catalog parts are this high efficiency compound)隔振器配方（手册中所有产品都是这种高效的配方） High efficiency高效 Provides little damping仅提供很小的阻尼 Shock Absorption Compound冲击吸收配方 Higher damping 高阻尼 Reduces “spring back” effect降低回弹效应 ;Variable of Load Capacity 可提供不同的载荷能力 Affects contact area 影响接触面积 Smaller ID carries larger load 中心直径越小，载荷能力越强 Aids in installation安装指南 “Installation” p. 24 – 26 in Catalog产品样本第24-26页 Mounting pins安装销 Center rod中心杆 Cable张紧带 ;Mounting Method安装方法;Mounting Method安装方法;No taper is the standard 标准形式是非锥面形状的。 Taper advantages 锥面形状端面的优势 Softer at low compression 低压缩时更软 Reduced stress in arc motions 弧形运动时可以降低应力 Improved fabric performance for tall, thin parts 用于又高又长的产品时，可以提高纤维层的性能 ;High tensile tire cord fabric 高强度轮胎纤维 Angled plies provide 层与层之间纤维成角度排列 Consistent cylindrical shape （被压缩时）保持圆柱形状 Load curve profile 载荷曲线 Stability 稳定性 Similar to an air spring与空气弹簧相似;;MarshMellow Operation 橡胶弹簧应用;When rubber is deformed, it flows to the path of least resistance like a fluid. 像流体一样，橡胶被压缩时会遵循最小阻力原则。 It forms a sphere with flat ends.那样会??成一个两端是平面的球形 The load is carried like a cylinder, pressure times area 载荷能力计算类似气缸，压力乘以面积 However, the area is only the size of the contact area of the rubber and metal ends 然而，面积只是橡胶与金属件的接触面积;As the height decreases in a MarshMellow, the cords pantograph, increasing diameter a
