TRUCK DESIGN OPTIMIZATION (TDOP), PHASE II ANALYSIS PLAN

The purpose of this document is to set forth the Analysis Plan which will be followed in the Truck Design Optimization Project (TDOP) Phase II. The Analysis Plan defines the means by which Type I (standard) and Type II (premium) freight car trucks will be characterized and compared. The specific objectives of the analysis task are: (1) to define the requirements for test data and simulation results which will establish performance specifications; (2) to determine the extent to which field test data can be extrapolated; and (3) to develop criteria for validating analytical models. The evaluation of Type I and Type II trucks addresses four important aspects of performance relating to railroad safety or effectiveness. The four are: lateral stability, trackability, curve negotiation, and ride quality. The Analysis Plan is divided into sections relating to each of the four performance regimes. Each section contains a discussion of performance indices, analysis requirements, model utilization, test data utilization, special considerations for Type II trucks, and summary.
