    Human factors problems in the design of vibration isolation systems: a contribution to the evaluation problem of passenger car suspension systems
    (College of Aeronautics, 1968-02) Fox, J. G.; Whitehead, G. D.
    1.0 Introduction In Appendix 1 of this report general procedures for the design and evaluation of vibration isolation, systems. are reviewed. It is shown that in general., a: vibration isolation system is adequate only when it enables a human operator to meet the objectives of some system by performing a task well enough and for long enough. If the vibration intrudes too far upon the operator's performance and endurance the system of which he is a part will not meet its objectives. There still remain examples today where inadequate vibration isolators limit the performance of a system. The agricultural tractor is one of these. It is not uncommon to see a tractor driver supplementing the tractor tyre spring by using his own vibration isolators - his legs.

    A review of data analysis systems
    (College of Aeronautics, 1965-09) Whitehead, G. D.
    This review gives an appraisal of 8 Automatic Time history reocrd analysis systems. The appraisal indicates the analytical capabilities, analysis flexibility and the cost involved in performing the analysis. It is suggested that in choosing such a system for an educational institution, some analysis speed and automation should be sacrificed for computational flexibility and operational adaptability. The review does not indicate that a specific machine be considered, but rather that an analysis system be built from a number of manufacturing sources.
