THIS paper outlines the reasons why a continuous static testing program of a new body design should parallel development of the model until the first road car is produced.
First, major deficiencies can be eliminated from the design before the road car is constructed, resulting in a considerable saving of time and money.
Second, continuous static testing leads to a structurally satisfactory road car, leaving road tests free for the solution of problems involving suspension design, ride, and noise.
Third, static testing points the way to efficient design of all structural components, whereas road test results are necessarily determined by overall structure.
Static tests, founded on sound engineering principles, can lead to the development of optimum designs, rather than the acceptance of given designs.
The writer stresses the need for tests which simulate actual service conditions, as well as correct interpretation of test results, based on a proper understanding of the difference between strength and rigidity.
