Opis:
The extortions that result in the vibrations of a hull of the combat vehicle have an impact on the tracked combat vehicle during the off-road driving. They may have a negative impact on the crew, internal equipment, shooting accuracy. A level of the hull loads depends on quality of the suspension system, which main responsibility consists in minimising an amplitude of the vibrations. Therefore, it is necessary both to improve a structure of the suspension system, and its components, as well as their optimisation. The tests of the driving smoothness of the vehicle and quality of the suspension elements can be realised both within a frame of the model tests and while driving in the real conditions. The assessment criteria of the driving smoothness are directly related to the negative influence of the vibrations to the human body. The suspension quality should be assumed both upon an execution of the vehicle prototype, and during the design or modernisation phase. It results both in reducing the time, and minimisation of the costs and risk related to the structure development. The model tests enable to evaluate the driving smoothness and comfort prior to an execution of the prototype. The tests on the test tracks in the final phase of the development are carried out in order to evaluate the driving smoothness.

Opis:
The paper deals with problems of the tram vehicle control in accordance with the criterion of the minimum electrical energy consumption. In this elaboration, the energy-saving control of the tram driving electric motors takes also into consideration the influence of cross-roads light signalling disturbing the smoothness of the vehicle traffic. In general, the light change during the tram running is here treated as the ride perturbation. Relations describing the tram traffic contain nonlinearities as a result of properties of motion resistances and owing to the magnetic circuit saturation in the motors. Determination of the run algorithm ensuring minimization of the electric energy consumption has been realized by application of the numerical method of differential equations solving and by using the optimization procedure. Calculation process takes many constraints into account, for example the adhesion effect connected with existence of a limiting force acting in the wheel circumference. Within perturbations caused by light signalling, computations of the tram energy-saving run were connected with the algorithm of the delay liquidation. In the case of greater time lags of the traffic, the ride delay must be liquidated during the run between some succeeding stops. Also here the best control strategy can ensure the electrical energy saving.
