Patent ID: 8321177

Claim:
A method for logging the performance of a vehicle suspension system by testing dynamic performance of at least one vehicle suspension system component, the method including the steps of: a. measuring the dynamic excursion of mass of an impulsive load with an electronic weighing system in response to a unit impulsive load, wherein the electronic weighing system is mounted onboard the vehicle and monitors the at least one vehicle suspension system component, and b. measuring an oscillation frequency of said at least one vehicle suspension system component in response to said unit impulsive load, and c. determining the damping ratio of the at least one vehicle suspension system component using the dynamic excursion of mass for each at least one vehicle suspension system component, and the maximum oscillation frequency of the at least one vehicle suspension system component wherein the electronic weighing system mounted on board the vehicle includes at least one load measuring element associated with one or more vehicle suspension system components, an electronic data log to receive information from all load measuring elements on the vehicle, the performance of the vehicle suspension system being logged over a known road section and comparing the dynamic excursion of mass of an impulsive load from each load measuring element.
