SHOCK INDEX CLASSIFICATION FOR HIGHWAY VEHICLES

A PROGRAM, JOINTLY SPONSORED AND PROMOTED BY THE ARMY, NAVY, AIR FORCE, AND MARINE CORPS, HAS PRODUCED A SHOCK INDEX CLASSIFICATION FOR HIGHWAY VEHICLES. THE INDEX IS AN EMPIRICAL RELATION AMONG THE STATIC MECHANICAL CHARACTERISTICS OF THE VEHICLE AND THE LOW FREQUENCY SHOCKS TRANSMITTED TO THE CARGO. IT IS RELATIVELY SIMPLE AND INTENDED TO BE A USER GUIDE FOR SHOCK TRANSMITTED TO THE CARGO DURING TRANSPORTATION. THIS PAPER GIVES THE FORMULAS AND METHODOLOGY FOR OBTAINING THE INDEX. THE FIRST PLANNED USE IS FOR TRAFFIC MANAGERS TO EFFECT A ROUGH BALANCE IN SERVICE BETWEEN THE VEHICLE CUSHIONING AND CARGO FRAGILITY. CARGOES WHOSE LOSS COSTS ARE SMALL COMPARED TO ADDED VEHICLE-CUSHIONING COSTS WILL ALSO BE BALANCED FOR OPTIMUM ECONOMICS WHEN THE INDEX RATINGS ARE KNOWN. A COMPREHENSIVE PROGRAM WILL EXTEND THE SAME CONCEPT TO ALL MODES. ALSO, SHOCK INDEXES OR SIMILAR EMPIRICAL FACTORS WILL BE DEVELOPED FOR CLASSIFYING HIGHWAY PAVEMENTS WITH REGARD TO SHOCKS TRANSMITTED BY VARIOUS HIGHWAY PAVEMENTS.
