Aerodynamic Load Experiment Setup

Abstract

This chapter introduces a series of model scale experiments undertaken at the TRAIN rig facility to assess aerodynamic forces subjected on an ISO container loaded onto a Class 66 hauled moving model container freight train in an open air and crosswind simulation. The TRAIN rig facility and crosswind generator, previously introduced in Sect. 2.1.1, are discussed in further detail in Sect. 5.1. Section 5.2 discusses adaptions to the moving model to include an on-board pressure monitoring system and data logger. Section 5.3 defines the coordinate system adopted for the aerodynamic load experiments and details of measuring positions. Trackside instrumentation, including measuring probes, position finders and ambient condition monitors are described in Sect. 5.3.2. The experiment methodology for the open air and crosswind sections, bringing together the experiment setup and instrumentation, is discussed in Sect. 5.4.
