NONLINEAR TYPE ELASTIC SUPPORTING BODY UTILIZING RUBBER SPHERE

摘要

PURPOSE:To greatly reduce the magnitude in the longitudinal direction by forming the present supporting body in the structure in which real spheres or semispheres are arranged in parallel on a surface and connected by thin flexible plates and forming a compression load-displacement diagram in the hardened stiffness nonlinear characteristic. CONSTITUTION:A sheet shaped flexible body consisting of one or a plurality of rubber balls (or the shape similar to sphere) arranged in parallel is used as elastic supporting body or shock absorbing body. When the used weight and the used space are provided, the hardness and Young's modulus (determined according to the weight ratio between natural rubber and cross linking agent such as sulfur), and the diameter of the sphere are determined by using a calculator such as a personal computer according to the theoretical equations.
