Portable Dynamic Brake Testing Apparatus for Mobile Underground Mine Equipment

摘要

A novel instrumentation system was developed that enables simple, quick, and accurate measurement of vehicular dynamics within low-speed ranges. The system, consisting of a microwave transceiver and microprocessor data acquisition and reduction system, measures the deceleration dynamics of low-speed mining and construction equipment. It makes the basic measurement; calculates key parameters such as average deceleration, initial velocity, stopping distance, and brake system delay time; and produces autoscaled graphs of velocity, acceleration, and displacement versus time.
