Abstract
The necessity to understand the real world suspension loads in ground based vehicles has led to the creation of an electronic strain gage instrumentation system. A method developed to dynamically record the normal loads delivered by the tires of an open-wheel racecar were tested on track and discussed. The forces transmitted by each of the vehicle’s four tires were recorded during a series of forward acceleration, braking, and skidpad exercises to determine the highest instantaneous lateral and longitudinal suspension loading. This data was used to verify the calculations and assumptions of a physics based analytical model that was concerned with the effects of lateral and longitudinal vehicular load transfer under acceleration.
