In India, we know only few things about the brake performance of commercial motor vehicles. The main reason behind collision of vehicles is due to faulty brakes and cost of brakes is more expensive for the trucking companies. Also force and wear of break are of great interest to the transportation community. We developed this project to check the performance of brakes in contrast with the existing method of visual inspection. For retrieving the break force and break wear over the life of new brakes in vehicles, scientists installed the Performance Based Brake Tester (PBBT) at Green County Weigh Station in Tennessee.
This project will calculate the braking force of each wheel end by using in-ground roller dynamo meters. The break force which is corresponding to Artificial Axle Loading (AAL) and vehicle weight will give the constant loads for data analysis. In this project, AAL will maximize each axle load to 80% Gross Axle Weight Rating (GAWR) by using hydraulically operated hook. In order to find where over break life, aftermarket brake drums and shoes will be provided to four industry partners who maintain fleets of class-8 vehicles. For supplying data in each category this project will check the Tankers, dry-box vans, dump trucks, and motor coaches. Each vehicle will be checked on a Performance-Based Brake Tester (PBBT) over the brake life, which may range from 8 to 18 months, at regular interval of time, which will differ from weekly to monthly dependent on the type of truck or vehicle.
The real-world data like weight of vehicle, brake force, brake-line air pressure, AAL and eccentricity of brake drums will be collected by the PBBT. The researcher measures thickness of brake pads with a caliper and collects registration number, mileage of vehicle. It monitors the test and ovality of brake drums with a digital indicator before and after the testing period to determine performance as a function of wear. I wrote test plan for the experiment, merging the information about the partners, the test procedure for the PBBT and device used to measure the eccentricity. By this experiment, we will get information about break performance in various industries and it plays an important role in utilizing the PBBT as a diagnostic tool for faulty brakes in future.
It explains the meaning of functional and data requirements of the application. The proposed system is client-oriented and gives complete review. It also provides disadvantages, assumptions and dependencies of the application. The developer of proposed system should meet the requirements of client. The developers’ technical view about client’s expectation of the application is included in the proposed system. It meets the main requirements and performance of the application and it gives correct meaning of the interface. (Up to here)
