braking force

Influence of operating factors on the efficiency of the vehicle brake system

The main system responsible for the safety of the car is its braking system. The efficiency of the braking system is assessed by several parameters, the main of which is the maximum braking force, which is generated in the braking mechanisms, usually it is disc or drum types of brakes. The analysis of peculiarities of designs of existing types of brakes of cars is carried out, advantages and disadvantages of each of them, characteristics of application and maintenance are substantiated.

Research of longitudinal compressive force in heterogeneous train when braking in curved track section

The article is aimed to determination of necessary condition of wheel rolling onto the rail head for heterogeneous train made up of empty and loaded cars using a simplified algorithm for computing the longitudinal compressive forces. It was investigated the distribution of the maximal compressive forces in the train sections during emergency and service braking. To determine the dynamic longitudinal compressive force the differential equations of the mass center movement of the fore and tail parts of the train are formulated.
