The paper presents the results of a study on the influence of seasonal conditions on the reliability of diesel and gas diesel vehicles. During the experiment were treated with statistical data on the failure of the two groups of trucks, methane-diesel and diesel operated under the same conditions. As a result of analysis found seasonal variations in the flow of failures between the two groups. Then the failures were divided into failures of components and assemblies cars such as engine, transmission gear and chassis of cars. This division has revealed the influence of seasonal conditions on the reliability of components and assemblies of diesel and gas diesel cars and their differences. Studies have shown the need for adjustment of norm in the planning of maintenance and procurement of spare parts for gas diesel vehicles.

The article presents a method of forming a rational structure of the truck fleet. This method allows to evaluate the effectiveness of means of transport for which there are no statistics on the operation under specified conditions. The same methodology takes into account the possibility of application gas-equipment on rolling stock and its impact on the change of technical and operating characteristics of the vehicle. The methodology used method of expert evaluations, taking into account the weight factors. In the first step introduced initial data on operating conditions, and a cargo nomenclature, technical and operational performance of the car and so on. Next it is determined whether there is information about the operation of the vehicle under specified conditions. In the absence of information, used the method of expert evaluations based on weighting factor. After filling out all the necessary information is made choice of truck that meet the specified requirements. Calculated the cost of transportation of cargo for selected vehicles on the basis of the performance of the vehicle and the cost of its operation.

Most important information about an environmental resistance (moisture, cyclic change of the temperature, ultraviolet radiation) of high strength composite material can be received at the compressive mechanical testing. The reinforcing fibers that are oriented along the specimens axis (or are oriented on the small angles relative to this axis) carry the main tencile loading. Conversely, at the compression the elastic and strength properties of the material, basically depend on the matrix properties. The specimens for mechanical testing are usually manufactured as relatively thin rectangular plates by winding or laying-up that corresponds to the ready composite parts. In order to eliminate buckling of the specimen at compressive test, its working length must be very shortened. So, this working part is unavalable for the extensometer instalaltion, and compressive strain of the specimen can be determined by the stroke of crosshead only. This stroke is a sum of very small contraction of the specimen and crosshead displacement due to elastic deformation of the testing machine. We determined the dependence of elastic deformation of the testing machine at the preliminary testing to exclude this deformation from the testing data. We present the features of the compressive testings and their numerical processing at the study of high strength GFRPs, and also the character of composite fracture studied by means of the scanning electron microscopy.
