A body mount design is provided for use of a microcellular polyurethane material in a body mount. The microcellular polyurethane material has a non-linear elasticity which is beneficial in a body mount design. The microcellular polyurethane material has relatively high elasticity under low loads for isolating small vibrations and has relatively low elasticity under high loads for translational movement of the vehicle body along with the vehicle frame. The design includes a first generally cylindrical member attached to a vehicle frame. A second generally cylindrical member is attached to the vehicle body. The second cylindrical member is disposed within the first cylindrical member and a first microcellular polyurethane member is disposed between the first and second cylindrical members.
Modèle d'un assemblage de carrosserie pour l'utilisation d'un matériau de polyuréthanne microcellulaire. Le matériau affiche une élasticité non-linéaire favorable à un modèle d assemblage. Le matériau présente une élasticité relativement élevée sous la pression exercée par de faibles charges pour isoler les vibrations légères, et comporte une faible élasticité sous des charges élevées pour un déplacement de translation de la carrosserie du véhicule le long du cadre. Le modèle inclut un premier et un deuxième éléments généralement cylindriques fixés respectivement au cadre et à la carrosserie du véhicule. Le deuxième élément cylindrique est placé à l'intérieur du premier élément, et un premier élément de polyuréthanne microcellulaire est placé entre les premier et deuxième éléments cylindriques.
