Abstract:

The article provides an overview of the methods of restoration and repair of various parts of the equipment: shafts, couplings, splined and keyed joints. Recommendations on the choice of methods, equipment and tools are given. In case of wear, the keyway is repaired by welding the face with subsequent milling. At the same time, the keyway size set by the standard is maintained. Such repairs are also possible: the keyway is expanded and deepened, completely eliminating the traces of wear, after which a stepped key is made to it. However, with such repairs, a high-quality connection is not provi

Abstract:

Experiments were performed to study vortex shedding behind a linearly tapered cylinder. Four cylinders were used, with taper ratios varying from 50:1 to 100:1. The cylinders were each run at four different velocities, adjusted to cover the range of laminar vortex shedding for a non-tapered cylinder. The flow was confirmed to consist of discrete shedding cells, each with a constant frequency. For a centrespan Reynolds number greater than 100, the dimensionless mean cell length was found to be a constant. Individual cell size was found to be roughly self-similar. New shedding cells were created

Abstract:

Interpolated cubic splines were used to estimate diameters and partial or total volumes for 285 trees from Pinustaeda L. plantations in southern Brazil. A range of 4 to 13 interpolated points was tested in an attempt to determine how many points are necessary to adequately represent stem taper. The various number of combinations with 13 or fewer points for interpolation were compared with a full spline of 16 points, which according to pertinent literature, estimates volume similarly to the traditional volume formulas (Newton, Huber, Smalian). The results showed that 10 well-placed points are n

Abstract:

The paper deals with representation of individual stem profiles of beech and oak in White Carpathian Mountains, Czech Republic. Due to complicacy and irregularity of stem profiles of most trees common taper functions are not applicable for individual stem profile description. Selected spline functions were used to model the irregular stem profiles. To fit complicated stem profiles with a spline more input points are needed than for regular stems. The splines were computed using four fixed input points representing diameters in four conventional heights (base diameter, stump diameter, DBH and t

A new model for the free transverse vibration of axially functionally graded (FG) tapered Euler-Bernoulli beams is developed through the spline finite point method (SFPM) by investigating the effects of the variation of cross-sectional and material properties along the longitudinal directions. In the proposed method, the beam is discretized with a set of uniformly scattered spline nodes along the beam axis instead of meshes, and the displacement field is approximated by the particularly constructed cubic B-spline interpolation functions with good adaptability for various boundary conditions.

Abstract:

Many structural failures in precast concrete buildings are initiated by connection failures. To avoid such failures, the connections should have enough strength to join the reinforcement bars between precast concrete panels. This paper presents the structural performance and behaviour of a proposed splice sleeve connection using generic steel pipe. The connection consisted of steel bars with tapered nuts confined in grouted steel pipes. The connections were subjected to increasing axial tension until failure. The results show that the use of smaller pipes gives better confinement effects and p

The collocation method is the method for the numerical solution of integral equations and partial and ordinary diﬀerential equations. The main idea of this method is to choose a number of points in the domain and a ﬁnite-dimensional space of candidate solutions.

The current paper involves developing, and a comprehensive, step-by step procedure for applying the collocation method to the numerical solution of free vibration of tapered Euler-Bernoulli beam.

Abstract The use of mechanical splices to connect steel bars is an important solution in many infrastructure projects worldwide. In Brazil, this system is rarely used.

It was found that the maximum power detected by a small taper angle probe was only -34.22dBm.

AbstractA novel Michelson interferometric hydrogen sulphide sensor coated with copper/reduced graphene oxide (Cu/rGO) composite membrane is proposed and fabricated. A section of endlessly photonic crystal fibre (EPCF) was sandwiched in two single-mode fibres (SMFs). One SMF was spliced and tapered with EPCF; the other SMF was connected with the Faraday rotator mirror to construct the Michelson structure. The cladding of the EPCF was coated by the Cu/rGO-sensing membrane, which was prepared by the dip-coating method. The obtained Cu/rGO-sensing film has a length of 25.0 mm. The fabricated sensi

Abstract:

Lack of generalized equations has prevailed in Brazil, because it is assumed that localized or climate-specific equations are needed. This study aimed to develop generalized stem taper and volume equations applicable to 11 eucalyptus clones and evaluate if climate variation impacts the accuracy of the estimates. A total of 693 trees evenly distributed across 11 clones at 21 sites were used for model fittings and predictive validation. The penalized mixed spline (PMS) approach was developed for predicting stem taper and volume along the stem profile. The Schumacher and Hall (1933) equation was

Abstract:

Harmonic drive has widespread applications for its compact size and high reduction ratios. It is often favored for electro-mechanical systems with space and weight limitation. In order to minimize the volume and improve its transmission capacity, more and more aborative design technologies are adopted. For structural analyses in assembly state and in transmission stage, Finite Element Analysis (FEA) can be widely applied to get proper parameters and performance. Flexspline usually endures large deformation under assembly force from wave generator. In transmission state, driving force leads to

Abstract:

Lateral extrusion, sometimes called injection upsetting, offers a product with central boss section having complete or segmented protrusions. Collar flanges, spur gear forms, spline or taper with shaft are examples of the products of produce by lateral extrusion. The aim of this study is to investigate the lateral extrusion of gear-like spline form in terms of forming load and load die filling ratio and comparison the results with those results obtained from a commercially FEM based programme named DEFORM-3D. A series of experiment has been carried out using solid lead billets with two differe

Chaotic global analysis of the RR-intervals from the electrocardiogram and preprocessing adjustments were undertaken. The effect of varying two parameters to adjust the Multi-Taper Method (MTM) power spectrum were evaluated. Then, cubic spline interpolations from 1Hz to 13Hz were applied whilst the spectral parameters were fixed. Precisely 1000 RR-intervals of data were recorded. Results. CFP1 and CFP3 are
