Assembly Variation Analysis of Incompletely Positioned Macpherson Suspension Systems Considering Vehicle Load Change

The assembly precision of wheel alignment parameters is vital to vehicle handling stability. Due to the vertical wheel displacement and compliant components in suspension systems, it is difficult to assemble qualified vehicles with proper wheel alignment parameters. In the assembly shop of the automobile factory, the adjustment of wheel alignment parameters is the most time-consuming process because it relies on trial and error. In order to provide a theoretical guidance to the precision control of wheel alignment parameters, this paper extends the theory of equilibrium equations of incremental forces (EEIF) to 3D compliant mechanisms. Constraint equations of kinematic joints are adopted to express the spatial relationships of different parts. A couple of fixed and floating joint coordinate systems (CSs) are used together to represent deviations of compliant components. The impacts of suspension part deviations on vertical wheel displacement and assembly deformations are well illustrated by such approach. Accuracy of the proposed method is verified by comparing with ADAMS simulation. The results show that the error rates of the 3D EEIF method are less than 5%. Furthermore, statistical assembly variation analysis of a Macpherson suspension is accomplished by using the proposed method and an optimized process strategy is put forward.

The Soviet Auto Giant

This chapter examines how the Soviet Union strove to acquire American mass production technology in order to create their own version of Fordism in the 1930s. It traces the origin and operation of one of the prestigious objects of the First Five-Year Plan: the automobile factory at Nizhnii Novgorod. After 1933, when the city changed names in honor of its scion Maxim Gorky, the Soviet River Rouge went by the official name of Gaz (Gor'kovskii Avtomobil'nyi Zavod); but to the Soviet press, it was known simply as the “Auto Giant.” The chapter then follows four men who helped the Auto Giant awaken and rise. Economist Nikolai Osinskii pushed through an ambitious agenda for Soviet motorization that culminated in the foreign technical assistance contract with the Ford Motor Company of May 1929. In fulfillment of this agreement, Stepan Dybets traveled to Detroit and led a group of Soviet engineers who were in charge of transferring Ford technology and know-how from the Midwest to central Russia during the years of the First Five-Year Plan. Meanwhile, as director of Gaz between 1932 and 1938, Sergei D'iakonov oversaw the uneven and troubled implementation of Fordism during the Second Five-Year Plan. Finally, Ivan Loskutov ascended to the helm of Gaz after Stalin's purges, and presided over the factory's redoubled embrace of Fordism in the late 1930s and World War II.

MODAL AND STRUCTURAL ANALYSIS STUDIES OF THE TRANSFER LINE CARRIER CONSTRUCTION

In this study, the analysis studies carried out to assist the design stages of the part transfer line to be used in an automobile factory and the experiences gained from these analysis studies are emphasized. These experiences are very important in similar product developments in industrial design. Design and analysis studies carried out prior to manufacturing ensure that production can be carried out without any problems. For this reason, special importance should be given to the design stages in the process and alternative solutions should be created by revising the design in every aspect. Analysis studies should be carried out to select the best design among these solutions. The finite element approach, which is the approach used by today's special analysis software, was preferred in this study. Many analyses were carried out on the model whose boundary conditions were determined and the real-life behaviour of the design was foreseen. In the analysis studies, modal analyses and structural displacements were carried out in order to understand the dynamic behaviours and the stresses will not exceed certain limits. A finite element based simulation software was used in the analysis studies. Here, the importance of design experiences based on past experiences has emerged in the optimization of the design. The design steps to be presented in the paper and the analysis results obtained through the design were also very useful in the prototype manufacturing phase and the transfer line was safely demonstrated. As a result of the trials, the transfer line was delivered to the customer and still fulfils its duty safely.

Documentation of party organization of the Moscow Automobile Factory named after I. A. Likhachev as a source on history of the company

The subject of this research is the documentation of party organization of the Moscow Automobile Factory named after I. A. Likhachev (known fully as the Public Joint-Stock Company – Likhachov Plant ZIL, Moscow Automobile Society AMO ZIL) as a source on history of the enterprise. The goal of this research consists  in determination of information capacity and possibilities of using documentary materials accumulated as a result of work of the primary party organizations of industrial enterprises of the Soviet period, namely with regards to the least studied aspects: social conditions, socio-psychological, and socio-cultural. The analysis of sources demonstrates that the materials of factory party organizations, particularly Moscow Automobile Factory named after I. A. Likhachev, represent one of the most valuable groups of sources in studying the history of a single company and industrial enterprise. They feature high information capacity on the key aspects of the company, including social. It is underlined that the party documentation was used by the Soviet researchers fragmentary and at times not objectively for multiple reasons; therefore, one of the tasks for the historians lies in comprehensive reconstruction of reliable scientific history of enterprises overall, and their party organizations in particular.

Impact of an Energy Monitoring System on the Energy Efficiency of an Automobile Factory: A Case Study

Energy-saving strategies cannot be implemented without having detailed and regular power consumption data of a facility. The installation of an energy monitoring and data logging system can help in planning energy efficiency improvement policies by providing daily, monthly, and yearly energy consumption reports and graphs. The purpose of this study was to demonstrate the impact of an energy monitoring and management system on the improvement of energy efficiency in the industrial sector of developing countries. This study introduced an energy monitoring and data logging system installed in an automobile factory in Pakistan. Energy consumption data, which also included power quality data, were collected with the help of energy analyzers and transmitted to a centralized supervisory control and data acquisition (SCADA) software for data logging and monitoring purposes. This system was developed by combining Modbus with industrial Ethernet to communicate real-time energy consumption data of the factory to multiple local and remote locations. Monitoring and logging the real-time energy consumption data helped the user to find the significant energy losses inside the factory and to implement various energy conservation policies inside the facility, resulting in energy efficiency improvement. The energy consumption results indicate that the proposed system can help achieve an approximately 8% improvement in energy efficiency.

History of formation and development of traumatological and orthopedic patients rehabilitation in Nizhny Novgorod region

Medical rehabilitation in our country is under reformation currently and new rehabilitation system model is being created. In this regard, it is particularly important to study path of our predecessors and pioneers of this scientific direction. The article analyzes the experience of organization and establishment of industrial rehabilitation system for patients and disabled persons, created on the basis of Nizhny Novgorod research Institute of traumatology and orthopedics and medical-sanitary unit of Gorky automobile factory in the 70-s of the previous century. The article focused on both medical and socio-economic efficiency issues of the established system, which has been a school of excellence in Russian Federation for many years. Knowledge of this experience could be of great value for current specialists, because, as our compatriot A.M. Gorky said, "Without knowing the past, it is impossible to understand the true meaning of the present and the goals of the future."
