A batch mixer is considered. The feasibility of developing a new type of mixers is presented. A literary review of domestic and foreign authors on this subject is made. The author's kinematic scheme of the mixer is presented. It describes the effect on the material mixed in the mixing chamber with respect to two mutually perpendicular horizontal axes. Movement features of material in the mixer suggest the presence of elements of the gyroscopic effect. Rotation of the mixing chamber is carried out by means of belt, chain and conical transmission. The resulting complex spatial motion of the material particles can be controlled by a frequency converter and the selection of appropriate gears. An algorithm for modeling the conical transmission for a mixer with a bi-directional rotational effect on the material is presented. Bevel gear is set on the carrier. Preliminary experimental studies have been conducted. A three-dimensional model of the bevel gear is presented. Adjustment of the installation dimensions is shown. A three-dimensional model of a bevel gear transmission, using the NX software product, is supplemented with a table for its calculation and an initial stocking model. The practical implementation of bevel gears in metal is shown. conclusions on modeling are made.

Periodical mixers are considered. The expediency of developing a new type of mixer is presented. Features of the material movement in the mixer allow to speak about the presence of elements of a gyroscopic effect. The mixing chamber is rotated by means of belt, chain and conical transmission. The resulting complex spatial movement of material particles can be controlled by a frequency Converter and the selection of appropriate gears or using a belt drive. An algorithm for modeling the drive unit of a mixer with a bidirectional rotational effect on the material is presented. The features of the drive unit and its components are considered. The task is to build a model of deformation of the drive unit of the mixer. The finite element method (FEM) for the drive unit of the mixer is used. Machine experiments are performed that implement fatigue calculations of the drive unit with a study in the SolidWorks Simulation environment. The results of static analysis of the drive unit operation in determining the deformation, static analysis of the drive unit operation in determining the voltage with varying torque are obtained. A variant of static analysis is presented when using a belt drive instead of a gear drive. The practical implementation of the mixer drive unit in metal is shown. Conclusions on modeling are made.

Noncircular bevel gear can achieve variable transmission between intersecting axes. This article proposes the design method of high-order noncircular bevel gear with concave pitch curve. The parametric equations for driving and driven gear, addendum and dedendum surface under given transmission ratio and axis angle are established in a spherical polar coordinate system. The tooth profile equation of noncircular bevel gear is derived according to the generation method by using bevel gear cutter. The three-dimensional model for noncircular bevel gear is developed to verify the correctness of the design method.

Extensive experimental studies on axial compressor bleed-flow systems have been carried out on a three dimensional model of a generic bleed-flow configuration typical for aero engines. The compressor flow is modeled as a clean annular flow. One row of stator vanes is used to impart a constant swirl upstream of the bleed system. The rig is designed modularly in order to allow for inexpensive changes in all of its components and therefore to enlarge the variability of the model. The research is focused onto the generation of an experimental data base, which can be used to derive correlations for the calculation of effective areas and pressure losses. Those data are gained using steady pneumatic measurement technique. In addition, the highly complex flow field in the manifold, which has an important effect onto the bleed-flow, is analyzed using Doppler-Global-Velocimetry (DGV). These measurements were conducted in collaboration with DLR Cologne, who have developed the DGV technique. In this paper the flow field in the manifold is analyzed in detail for two different configurations featuring two and four bleed ducts, respectively. Furthermore the use of a flush design of the slot is compared with a lip design. These data are compared to results from the literature achieved using 2-dimensional configurations.

Oval bevel gear is a kind of noncircular bevel gear which can achieve variable transmission between intersecting axes. We design the pitch curve by spherics cosine theorem in spatial polar coordinate because the pitch curve of oval bevel gear is not the planar curve. The bevel gear cutter is introduced, and we get the Three-dimensional model of oval bevel gear through extended development of UG. This method can make the calculation accurately, easily and get a wide variation of transmission ratio.

This article describes the development of a new three-dimensional model of the British building stock, called ‘3DStock’. The model differs from other 3D urban and stock models, in that it represents explicitly and in detail the spatial relationships between ‘premises’ and ‘buildings’. It also represents the pattern of activities on different floors within buildings. The geometrical/geographical structure of the model is assembled automatically from two existing national data sets. Additional data from other sources including figures for electricity and gas consumption are then attached. Some sample results are given for energy use intensities. The first purpose of the model is in the analysis of energy use in the building stock. With actual energy data for very large numbers of premises, it is possible to take a completely new type of statistical approach, in which consumption can be related to a range of characteristics including activity, built form, construction and materials. Models have been built to date of the London Borough of Camden and the cities of Leicester, Tamworth and Swindon. Work is in progress to extend the modelling to other parts of Britain. Because of the coverage of the data, this will be limited however to England and Wales.
