LIMITING PERFORMANCE OF SHOCK ABSORBERS IN FREIGHT CARS
The problem of determining the limiting performance of a freight car shock absorber (cushion) in protecting ladings under crash considitions is considered. This work differs from the usual approach in that rather than analyzing (optimizing) a specific absorber configuration, e.g., prescribed set of springs and dashpots, the absolute optimum absorber behavior is computed regardless of configuration. For the problem treated in detail here, performance is measured in terms of peak force transmitted to the lading for a specified bound on cushion travel distance. The limiting performance problem is formulated as a linear programming problem. Numerical examples are included.
