ANALYSIS OF TRUCK BOLSTER CENTER PLATE RIM RESPONSE TO IMPACT LOADS

The impact of a moving freight car into a string of standing cars results in a large longitudinal load acting on the center plate rim of the truck bolster. The load is the result of the rapid deceleration of the truck. The dynamic characteristics of this load and its effects within the rim are discussed. Analytical procedures are described for processing strain gage data to determine the location on the rim where the load is applied.
