| Abstract [eng] |
This work examined the case of the trailer aerodynamics, as a compound, consisting of a vehicle and the trailer. In the first part of the car and carried out their maximum aerodynamics testing. In this section the different trailers carried out analysis, analysis of different cars, in the case described the influence of the trailer car. In the second part shall be selected on the proper method of experimental tests to barter. Experimental trials to determine the strength of the resistance of the trailer coupling is required, which will be able to capture at the time operating the trailer air resistance produced by coupling the trailer must meet the following requirement: change the location of the original hook, without losing any of the distance between the trailer and the car, that shouldn't affect the results obtained. The third part of the test results from the experimental estimated the force acting on the trailer, and the resistance of the calculated theoretical results obtained compared to the resistance of the trailer. In the fourth paragraph to make the economic calculations. From the experimental results of the test set to the resistance of the trailer was influenced by different fuel consumption cars. And the estimated quantity of fuel consumed as much as an additional full car eye-catching trailer. In accordance with the objectives described in the conclusions of the work. |
