System Objective

The task of creating a method for constructing components and parts of a locomotive drive, allowing not only to simulate the physical properties of the latter but also to form and automate the recognition of technical solutions, is considered. A model of a traction drive, which is a system of sets of descriptions of real objects of the set which makes it possible to create mathematical models of the structure in the form of a set of related elements included in the libraries of well-known solutions, is proposed. In contrast to previously known methods based on the procedure of creating new solutions under which a prototype of the structure is made and then improved on the basis of an empirical analysis of its development (while the design task is to create new structures). In the proposed method the basis for the construction of the technical system objective model is the classification of technical systems. Solutions to eleminate jamming of the sleeves of the axes with the transverse movement of the engine are proposed. A patent for the invention and two patents for the utility models are obtained.

The issues of development of traction drives of locomotives are considered. It was found that with the existing limitations of the traction force and the speed of continuous operation, asynchronous traction motors do not have clear advantages over collector motors. The possibility of creating collector motors for electric locomotives with a power equal to the used asynchronous ones has been proved, new technical solutions have been proposed for units that ensure the reliability of the latter when using high-torque motors (elastic gearwheel with chevron teeth, two-layer rubber-metal hinge, rubber-cord clutch options), as an optimal solution for the drive with collector motors, it is proposed to use a drive with a support frame motor and an axial gearbox. The directions of research necessary for the practical implementation of drives with a high-torque traction motor are determined, it is proposed to conduct research on the feasibility of creating diesel locomotives with bogies, unified with electric locomotives. The proposed solutions received two patents for inventions, eight patents for utility models, two patent applications were filed.

Work objective is to develop a patentable design of locomotive traction drive mechanisms using the example of a suspension unit. Research methods: object modeling method, analytical methods for calculating dynamics of rolling stock. Research results and novelty: the design of the railway electric motor suspension unit, which will reduce costs in the course of maintenance and repair of a locomotive with a solid gear by increasing the reliability of the suspension unit parts, eliminating their wear, has been developed; a compensation coupling device has been devised. We will synthesize the object model of a technical system based on the identification of its typical structure by classifying technical systems. Conclusion: the application of the object modeling method together with the object model allows avoiding errors in the development of new designs of technical objects based on existing comparables and eliminates defects of the selected prototype. The use of the object modeling method makes it possible to synthesize patentable designs of the locomotive underframe mechanisms.

Definition Of

The paper reports the consideration of the problem in choice and use of the locomotive traction drive design procedure giving possibilities both in properties and parts modeling, and in the automated identification of design solutions of latter. The object model of a design solution as a structure including the totality of object descriptions allowing the synthesis of engineering solution models as a multitude of interrelated elements described in the libraries of well-known designs. The method differs from the earlier ones in which the creation of new solutions is stipulated by the definition of a prototype and then by its development in accordance with the tendencies revealed empirically. In the method developed the synthesis of a design object model is based on engineering system classifications. The integrated object model of a traction drive involves two parts: first, the multitude hierarchy of the traction drive description for different methods of an engineering solution schematization, secondly, a library which has descriptions of standard objects in the form of a hierarchal structure of functional interaction between elements (I-graph). The search of similar objects in the library takes place at the level of the definition of drive functional elements with the aid of the matrices of similarity measures. There are given offers for the increase of reliability and loading capacity of a rubber-cord clutch of a locomotive traction drive. There are obtained three patents for utility models and an invention patent on the solutions offered.

A number of computing systems devoted to the averaging of electron images of two-dimensional macromolecular crystalline arrays have facilitated the visualization of negatively-stained biological structures. Either by simulation of optical filtering techniques or, in more refined treatments, by cross-correlation averaging, an idealized representation of the repeating asymmetric structure unit is constructed, eliminating image distortions due to radiation damage, stain irregularities and, in the latter approach, imperfections and distortions in the unit cell repeat. In these analyses it is generally assumed that the electron scattering from the thin negativelystained object is well-approximated by a phase object model. Even when absorption effects are considered (i.e. “amplitude contrast“), the expansion of the transmission function, q(x,y)=exp (iσɸ (x,y)), does not exceed the first (kinematical) term. Furthermore, in reconstruction of electron images, kinematical phases are applied to diffraction amplitudes and obey the constraints of the plane group symmetry.

Macromolecular Systems

The most advanced macromolecular materials are found in plants and animals, and certainly the connective tissues in mammals are amongst the most advanced macromolecular composites known to mankind. The efficient use of collagen, a fibrous protein, in the design of both soft and hard connective tissues is worthy of comment. Very crudely, in bone collagen serves as a highly efficient binder for the inorganic hydroxyappatite which stiffens the structure. The interactions between the organic fiber of collagen and the inorganic material seem to occur at the nano (scale) level of organization. Epitatic crystallization of the inorganic phase on the fibers has been reported to give a highly anisotropic, stress responsive, structure. Soft connective tissues also have sophisticated oriented hierarchical structures. The collagen fibers are “glued” together by a highly hydrated gel-like proteoglycan matrix. One of the simplest structures of this type is tendon which functions primarily in uniaxial tension as a reinforced elastomeric cable between muscle and bone.

Quantitative recording of electron patterns and their rapid conversion into digital information is an outstanding goal which the photoplate fails to solve satisfactorily. For a long time, LLL-TV cameras have been used for EM adjustment but due to their inferior pixel number they were never a real alternative to the photoplate. This situation has changed with the availability of scientific grade slow-scan charged coupled devices (CCD) with pixel numbers exceeding 106, photometric accuracy and, by Peltier cooling, both excellent storage and noise figures previously inaccessible in image detection technology. Again the electron image is converted into a photon image fed to the CCD by some light optical transfer link. Subsequently, some technical solutions are discussed using the detection quantum efficiency (DQE), resolution, pixel number and exposure range as figures of merit.A key quantity is the number of electron-hole pairs released in the CCD sensor by a single primary electron (PE) which can be estimated from the energy deposit ΔE in the scintillator,
