摘要:
A diesel-electric locomotive includes an assembly including a diesel engine and a generator, to which a drive unit is connected. The diesel engine is connected to a cooling system holding fluid. The drive unit is electrically connected to a braking resistor. There is provision for the braking resistor to be arranged in the cooling system so as to give off heat to the fluid. For example, the braking resistor is connected to a separate heating voltage source which may be, for example, a voltage source in a second locomotive which is coupled to the locomotive in a traction grouping.

A diesel-electric locomotive includes an assembly including a diesel engine and a generator, a drive unit and a control device, connectable to control devices of other locomotives. Further, a traction grouping includes at least two such diesel-electric locomotives, the locomotives being connected to one another by a control connection. There is provision for a power line to be present with terminals for power lines of other locomotives. In the traction grouping, the locomotives are connected to one another by a power line.

A method and a device for simulating a body that is moved in a translational or rotational manner. The method includes detecting a force that acts on the body or a torque (MW), and assigning a reference mass or a reference moment of inertia (Jsoll) to the body. The force or the torque (Mw) and the reference mass or the reference moment of inertia (Jsoll) are used to determine a reference speed (ωsoll) for a speed control which controls an actual speed (ωist) using a control transmission function (G(s)), and the reference speed (ωsoll) is determined by means of a transmission element using a transmission function (P(s)) that is reciprocally proportional to the control transmission function (G(s)).

A diesel electric locomotive includes a main generator for a drive apparatus and an auxiliary generator for auxiliary appliances, connected to a diesel engine. The main generator is connected by a first rectifier to the direct current traction intermediate circuit of the drive apparatus. The auxiliary generator is connected via a second rectifier to a direct current auxiliary operation intermediate circuit of the auxiliary appliances. The main generator is likewise connected via the rectifier and a DC/DC converter to the direct current auxiliary operation intermediate circuit.
