A NEW computer-controlled inertia dynamometer which tests cv braking systems and friction materials has been installed by the Research and Development Division of Cape Friction International Ltd.
The new machine, which has one of the most advanced control systems ever used in an inertia dynamometer, has been designed to meet all future brake-testing requirements for front and rear brakes of every type of cv.
Weighing 20 tonnes, the dyna
mometer is controlled by a Digital Equipment Incorporation LS1 11 microprocessor minicomputer coupled to two visual display units, a line printer, and graph plotter.
A vehicle manufacturer's test program can be fed into the computer and run through automatically.
Test results are fed on to cassettes or discs, and the computer's memory allows data processing work to be carried out at the same time as the machine is in operation so producing results almost as soon as tests are completed.
Don International Ltd is at Hendham Vale, Manchester M9 1SX.
