Present cable trolley brakes used in material transfer or overhead trolley transport systems uses twin shoe caliper brakes operated by solenoid. These brakes are not fail safe, means that slip occurs between cable and brake caliper. Sometimes overloading leads to wear of brake shoe material. The failure of brake system may increase the chances to loss of life of occupant. These conventional cal...

For the safety problem of heavy duty vehicles running on long downhill sections, a model was built for the application of engine brake and service brake combination based on test results. And a model of brake temperature rise for heavy duty vehicles running on long downhill sections was also established. For different braking modes, gear positions, speed and downhill slopes, brake temperature r...

In this paper, we first establish the Bott-type iteration formulas and some abstract precise iteration formulas of the Maslov-type index theory associated with a Lagrangian subspace for symplectic paths. As an application, we prove that there exist at least [ n 2 ] + 1 geometrically distinct brake orbits on every C compact convex symmetric hypersurface Σ in R satisfying the reversible condition...

We developed a passive haptic technique, using the brake of a DC motor, to create a greater perception of impulse force. We found that when using the brake of a DC motor, delivering two short pulses immediately prior to the main brake significantly increases the operator’s perception of impulse force. This finding was verified during our empirical assessment. In the experiment, all five partici...

A Functional Virtual Prototyping full vehicle model for a tri-axial heavy-duty truck is built, and the nonlinearity of suspension dampers and tires is also considered. With the trajectory of full vehicle gravity center, longitudinal tire force of front wheel, longitudinal acceleration, lateral acceleration, yaw rate and pitch angle as the evaluation indexes of brake property, the influences of ...

Ghana in recent years has seen dramatic increase in vehicular growth. Vehicular transport in Ghana is growing with increased socio economic activities. With so many cars on our roads, the rate of vehicular accident has also increased with many people died or sustained serious injuries in traffic accidents. This study reports on the brake failure and its effect on road traffic accident in the Ku...

The purpose of this work is to present a study of the thermomechanical behavior of the automotive disc brake during the braking phase. The first analysis is performed on the disc-pad model without the presence of thermal properties. Structural performance of the disc-pad model such as deformation and Von-Mises stress is predicted. The case of thermoelasticity on the same model with the inclusio...

We have previously demonstrated an abnormally delayed mean brake response time and an increased frequency of abnormally delayed brake responses in a group of neuropathic diabetic drivers compared with a control group of drivers with neither diabetes nor lower extremity neuropathy. The objective of the present case-control study was to compare the mean brake response time between neuropathic dia...

A Magneto-Rheological (MR) fluid brake is a device to transmit torque by the shear force of an MR fluid. An MR rotary brake has the property that its braking torque changes quickly in response to an external magnetic field strength. In this paper, the design method of the cylindrical MR fluid brake is investigated theoretically. The mechanical part is modeled using Bingham’s equation, an approa...
