Investigation of Transient Processes in Electromechanical Brake Units Taking into Account Armature Movement Behavior

The paper is concerned with transient processes taking place in electromechanical brake units depending on their control circuit. Laws of current and electromagnet flux linkage variation were considered in various operating modes taking into account armature movement behavior. The research group developed and analyzed a brake unit mathematical model in the form of a differential equation system taking into account its design features and operating modes. The mathematical model was used to develop brake unit simulation models in Simulink environment for various control circuits including the one with forced opening of the brake friction unit. The simulation models were used to investigate the transient processes in the brake unit depending on the change in its parameters and some recommendations were given on the choice of the most appropriate forcing schemes.
