Construction and Operation of Brake Testing Dynamometers 530237

FORMULATION of a standard test code covering the use of brake testing dynamometers has been completed, approved, and published in the 1953 SAE Handbook as a recommended practice. Increasing use of these brake testing machines has made it apparent that brake evaluation should be reduced to common terms in order to compare performance characteristics. The purpose of this paper is to facilitate use of the code by presenting additional explanatory information.
On the basis of both laboratory and field experience, the working committee has accumulated data covering design features of the dynamometer, dynamometer instrumentation, general features of the test code, and correlation of dynamometer and road tests.
The working committee which formulated the code - and wrote the report given here - includes the following members:
  • R. K. Super (chairman), Timken-Detroit Axle Co.; D. J. Bonawit, Marshall-Eclipse Axle Corp.; D. P. Dyer, Budd Co.; R. A. Goepfrich, Bendix Products Corp.; G. H. Hunt, Motor Wheel Corp.; J. F. Johnson, Raybestos-Manhattan, Inc.; A. E. Kimberly, Chrysler Corp.; G. K. McCann, Ford Motor Co.; E. O. Reynolds, American Brakeblok Co.; W. S. Rigby, Wagner Electric Corp.; and E. H. Wells, Jr., Johns-Manville Corp.
