“…The wear is usually reported in terms of weight loss of the pad and thickness loss for the drum. A comparison of Chase Machine data for several material combinations with that from an inertial dynamometer was reported by Tsang et al (1985). The test results from the two machines were inconsistent.…”

PrefaceThis report was prepared as an information resource for the development of advanced brake materials for heavy vehicles. This research is sponsored by the U.S. Department of Energy, Office of Transportation Technologies. It is part of an initiative aimed at reducing the running resistance while improving the safety of on-highway heavy trucks. Selected information on aircraft brake materials was included for comparison purposes. Data in this report have been compiled from a variety of commercial and non-commercial sources. The validity of the data in this compilation is the responsibility of the originators, and information contained herein should be used mainly as a guide and for the sake of comparison. Normally, IS0 units are used in ORNL reports, but in this case, the units have been ,reported in the measurement systems that were used in the original references. They reflect the diversity in current preferences for units of measure in the commercial brakes industry.

“…The inertial dynamometer is used to evaluate full sized brakes but this is a very time consuming and expensive process. In contrast, the CHASE dynamometer uses a small amount of friction material rubbing against a drum and it requires a shorter testing time than the inertial dynamometer [5].…”

The thermal behaviour of a disc brake is a critical factor that needs to be considered at the design phase. Most researchers utilise a full size brake dynamometer or a simple pin-on-disc rig to experimentally evaluate the performance of a friction pair (disc and pad). In the current paper, a scaling methodology is proposed to evaluate the thermal performance of a disc brake at a reduced scale. The resulting small scale disc brake has the advantage of low cost and reduced development time. The proposed scaling methodology was validated by comparing the results for the full and small scale discs using a conventional brake dynamometer. In addition, a two dimensional axisymmetric transient thermal finite element model was developed using Abaqus software to assist in the validation of the scaling methodology. The numerical simulations confirmed the equivalence between the full and small scale disc thermal performance using the proposed scaling methodology and also gave good agreement with the experimental results. It is concluded that the scaling methodology is an important tool with which to evaluate the thermal performance of disc brakes in the early design phase.Keywords: Disc brake, thermal performance, dynamometer, small scale.The ratio of heat flux into the pad to the total heat flux M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT

“…Inertia dynamometer is used to evaluate a full size brake lining material or brake system by simulating vehicles braking process but it is time consuming and more expensive. On a smaller scale, CHASE dynamometer features low capital expenditure and shorter test time (Tsang, 1985). Chase machine uses a small sample of friction material with a size of 1 inch x 1 inch x 0.25 inch.…”
