The consultant encounters major differences in language, economics, and culture. He finds smaller markets, more intrusive governments, and more masters to serve. Research on the country's history, political system, economics, culture, industry and agriculture is essential preparation. Probably the biggest unique requirement is empathy for people of other cultures. Restructuring the Agricultural Machinery Industry in Hungary originally involved primarily new machine tools. As a result of a World Bank study team, it shifted its emphasis somewhat to include a rationalized product line, less materials handling, and more training. Farm Equipment Manufacturing Technology Centers in India started with a concentration on additional machine tools in a design institute. The design team's study placed more emphasis on training and on improving the interaction between designers, manufacturers, and farmers.

This research compares the responses of a vehicle modeled in the 3D vehicle simulation program SIMON in the HVE simulation operating system against instrumented responses of a 3-axle tractor, 2-axle semi-trailer combination. The instrumented tests were previously described in SAE 2001-01-0139 and SAE 2003-01-1324 as part of a continuous research effort in the area of vehicle dynamics undertaken at the Vehicle Research and Test Center (VRTC). The vehicle inertial and mechanical parameters were measured at the University of Michigan Transportation Research Institute (UMTRI). The tire data was provided by Smithers Scientific Services, Inc. and UMTRI. The series of tests discussed herein compares the modeled and instrumented vehicle responses during quasi-steady state, steady state and transient handling maneuvers, producing lateral accelerations ranging nominally from 0.05 to 0.5 G's.
