The design of the working body planner slopes for liner-tamping-finishing machine VPO-3000. Based on the analysis of existing designs of planners ball-fin track machines (VPO-3000,SZP-600R,PB-01,SS-3,ELB-3MK,ELB-4K),finding to operate on a network of West-Siberian Railway selected under the most-walked analogue - plow machine SZP-600r.The proposed project design of all structural elements of the plow SZP-600R has been changed in view of the desired trajectories scheduler slopes and its geometrical layout on the machine VPO-3000,as well as taking into account the requirements of the design and of top-Story-of way,in particular gravel ballast,after work on her cleaning ballast cleaner MF-600. The selection of geometric parameters and the calculation of design elements scheduler slopes are made using APM WinMashin programs according to the real conditionscess of the load operation and,in particular: arrow with the plow is in working position and performs cutting and Zdzvizhkou crude ballast for support of contact network; arrow disclosed at the maximum angle ?; plows are not disclosed and are located along the axis of the boom. The developed design planner slopes allows removal of contaminated ballast portion of the railway line,as well as other operators,radio planning prism slopes. The proposed project will improve the machine VPO-3000 allows the excluded-tained from the technological process of modernization of railroad tracks Add-tional machine to remove the contaminated site ballast,which reduces the cost of performing the work.

The authors propose a model of justification of the duration of the operation liner-tamping-straightening and construction machinery. Using this model, we can evaluate the efficiency and reliability of machines on any object. This allows you to most reliably predict the timing of production of certain types of works and their cost at the design stage. The article presents the indicators of full-scale tests and the estimation of reliability of manufacturing operations. One of the main factors of reliability of work of construction machines is the utilization of their time. All normative documents are obsolete data on the utilization of machines during the working time, which need updating, as the machines are constantly improving. To assess the reliability of working machines, the authors developed a database of the results of field tests liner-tamping-straightening machines, cranes, excavators, bulldozers, pipe layers, drilling rigs and dredges. To prove the validity of database values according to the results of full-scale tests were carried out two stages of verification: logical and mathematical. After sampling in accordance with GOST R 8.736-2011 was verified that it belongs to the law of normal distribution using the criterion of Pearson agreement. It was further calculated the reliability and risk of the planned volume of work in scheduled period of time. When it was considered the utilization ratio of machines time and the risk of deviation from the mean. The proposed approach to the assessment of duration of liner-tamping-straightening and construction machinery can be extended to any type of equipment and will allow to obtain numerical values for evaluating the reliability of production work in the scheduled time, which is very important in the construction, repair and maintenance.

The algorithm of constructing the confidence interval of the model estimating the reliability of liner-tamping-straightening machines. The basis for assessing the reliability of transport-technological process initiated the concept of reliability, as the probability of reaching a liner-tamping-straightening machines ultimate goal in the manufacture of track work. One of the main factors reliability of track machines is the utilization of their time and availability to work. The guidelines are outdated factor data used during the working time that must be updated, as the machines are constantly being improved. According to the results of field testing of the liner-tamping-straightening machines was established database of values of the coefficients of availability and utilization over time. The data base values were recorded, the last two stages of verification: logical and mathematical. In the article the example of constructing a confidence interval values of the coefficient of use of time depending on the complex index of reliability: availability. To create the model formed the sample values from the database. After sampling in accordance with GOST R 8.736-2011 State system for ensuring the uniformity of measurements. The direct measurement repeated. Methods of processing the results of measurements were tested for their adherence to the law of normal distribution using the goodness of fit Pearson. Then built a model of the utilization of time depending on the availability liner-tamping-straightening machines (regression equation) and the confidence interval of the model. The proposed model works liner-tamping-straightening machines allow us to predict the main complex organizational and technological performance of a specific machine at the design stage of technological processes of track work. This method is versatile and can be used to assess the technical reliability of any machine systems, complete sets and individual cars.

The models of complex organizational and technological parameters of operation of liner-straightening machines cyclic action on the example of the VPR-02 and VPRS-02 using a probabilistic assessment of the reliability of their work. For her study conducted two etapa checks: logical and mathematical. After sampling in accordance with GOST 8.207-76 inspect it belongs-rise normal distribution using Pearson's chi-squared test. Next calculated reliability and risk completion of the planned scope of work machine systems, complexes, components and individual machines in the planned period of time. The models are based on actual field tests of databases, technical and economic indicators of machines, components and systems in real operating conditions. This model optimizes track works with a given reliability at stave-builder, all kinds of repair and current maintenance of railway track. And also give the opportunity to the WHO-define more rational modes of operation of track machines for you, edits, tamping and straightening the railway line, thereby increasing pa O-workings of these machines. They enable organizations operating these machines more reasonably expect the required number of cars processes track works, their cost and labor. The proposed method models quantify the technical reliability of the liner-straightening machines; allow predicting the main complex organizational and technological performance of a particular machine at the design stage of technological processes track works. This method is versatile and can be used to evaluate the technical reliability of any machine systems, components and separate machines.
