FREIGHT CAR CUSHIONING WITH VARIABLE ORIFICE HYDRAULIC SHOCK ABSORBERS

Cushioned freight car impact tests and test data are often misinterpreted. By combining experience obtained during several years of impact testing with a theoretical analysis of the physics of impact and performance of a variable orifice hydraulic cushion device, reasons for this misinterpretation are developed. The effect of not providing a safety factor in the optimization of the hydraulic cushioning design is discussed.
