Gyro-Accelerometer Analysis of Riding-Quality 290001
This paper describes the construction, theory and some uses of the Gyro-Accelerometer, an instrument capable of recording angular velocity, angular acceleration and the total angle turned. The design and development of this instrument came as the result of research into the riding-qualities of automobiles conducted by the Department of Mechanical Engineering at the State University of Iowa. These investigations demonstrated the necessity of measuring angular motions under road conditions which was impossible with available equipment. The instrument furnishes an analysis of angular movements whereby the characteristics of the springs and shock-absorbers can be so matched as to give the body the lowest values of angular acceleration and therefore the best riding-quality.
The description of the Gyro-Accelerometer and some of its applications should serve as the basis for a better understanding and appreciation of the results of riding-qualities tests and personal-opinion curves which will be the subject of a paper to be presented by Professor Fox at the Summer Meeting, Saranac Lake, June 25 to 28.
