Abstract:

The tracking lag error of a single axis in non-circular grinding is hard to be reduced due to the big inertia of grinding carriage and the large acceleration of crankshaft. Thus, it’s unsatisfied to improve the contour precision of crankpin just by enhancing the tracking precision of a single axis. To obtain a more accurate contour, the cross-coupled control system is designed based on the approximation that the coupled motion between the rotation axis of crankshaft and the linear axis of grinding carriage is simplified as the coupled motion between two linear axes. And then the control strate

Abstract:

Hydraulic transportation of the piped carriage is a new energy-saving and environmentally-friendly transportation mode. There are two main states in the conveying process, stationary and moving. In the process of hydraulic transportation of the piped carriage, the study of the stress of the water flow act on the cylinder wall of the piped carriage can help to improve the design of the piped carriage structure and even the selection of piped carriage materials. The distribution of flow velocity around the stationary piped carriage and the stress distribution on the cylinder wall of the stationa

Abstract:

Multi-axis winding machine can realize automatic winding of composite elbow, but its mechanical structure and control system is complex, which restricts its industrial application. In this paper, two-axis FRP elbow winding machine applied teaching and playback method is designed, which accomplish the winding of elbow by controlling the rotation motion of the mandrel and the reciprocating motion of the carriage along a semicircular track. In teaching mode, the positions of spindle and carriage are collected and stored as teaching document when the spindle rotates a certain angle, while in playb

Abstract:

Wheel slip model is an important aspect of vehicle driving stability and safety control. However, in most of the carriage movement models friction forces and wheel slip effect are being neglected. This paper raises the problem of wheel slip in dangerous driving and autonomous vehicles under critical driving modes, then tasks the modeling of movement of an individual vehicle is considered. These are two tasks of nonholonomic mechanics: 1) the movement of a wheelset without wheel slip (two disks freely mounted on an axis) along an inclined plane in the field of gravity, and 2) the movement of a

Abstract:

In industrial fields, it is frequently necessary to measure surface roughness in confined spaces such as boreholes and grooves in workpieces. However, the surface roughness of a narrow borehole can be measured only up to a few millimeters from its end when using a small stylus. Alternatively, destructive measurements must be performed. We previously proposed a novel surface roughness measurement sensor. To make the sensor sufficiently small, we used a stylus with a cylindrical mirror and a lensed fiber instead of a conventional inductive pick-up. The proposed sensor converts the signal used fo

Abstract:

The aim of the article is to present the alternative to the very well known hub and spoken approach to intermodality when freight scale is small. When usually the blocked trains operate between two big intermodal hubs, here the concept of on‐line blocking of intermodal transport units (ILU) is presented. The article investigates functional interrelations between the carriage of on‐line blocked ILU and the structure of transport network. In order to forecast the flows of on‐line blocked ILU the indirect model has been chosen which enables us to evaluate two important aspects: the first one is t

Abstract:

Employing matched asymptotics, we extend the recent theory of Mei (1986) to study the phenomenon of upstream influence by a slender ship moving near the critical speed. For a special class of channel width and ship slenderness, it is shown that the response on the sea surface is essentially one-dimensional with the wave crests perpendicular to the ship's axis. In particular, solitons are radiated upstream. The hydrodynamic pressure on the ship, as well as the total sinkage force, wave resistance and trimming moment are calculated. These forces are functions of time despite the constant speed o

Abstract:

It is suggested that IL-23/IL-17 axis and single nucleotide polymorphisms (SNPs) of IL23R may have crucial role in pathogenesis of Crohn’s disease (CD). Thus, we sought to assess the IL23R SNPs contribution to susceptibility and phenotype of CD. We recruited 117 CD subjects and 117 controls from Poland and 30 CD subjects and 30 controls from Bosnia and Herzegovina (B&H). Two common IL23R SNPs: rs1004819, rs7517847 were genotyped using TaqMan SNP assays. In the Polish population it was found that allele rs1004819: A increases the risk of CD, while allele rs7517847: A is protective against d

Abstract:

ABSTRACTThis paper deals with the actuation system design of a full-scale morphing aileron for regional aircraft. The aileron is allowed to smoothly change its geometrical configuration and perform the in-flight transition from a baseline shape to a set of optimal morphed ones pre-defined on the basis of aerodynamic requirements. The design of such innovative aileron is aimed not only at substituting the conventional aileron installed on a real aircraft but also to provide additional functionality. The aileron is free to rotate around its main hinge axis and it is also allowed to smoothly modi

Abstract:

AbstractHealth outcomes associated with Blastocystis sp. and Dientamoeba fragilis are disparate and controversial, ranging from health benefits, to years of asymptomatic carriage, through to severe illness. Evidence that Blastocystis sp. and D. fragilis are commensal members of the gut microbiota is growing. Despite this, little to no research exists investigating the potential effect of these protozoa on psychological symptom expression. As such, the aim of this retrospective cross-sectional study was to be the first to investigate the effect of protozoan carriage on severity of Depressive, N

This diploma thesis deals with the design of a two-axis multi-spindle lathe carriage. In the first part, there is made a research, and its aim is to find possible variants of design solutions. After the best rated variant was selected, the thesis further continues with the necessary technical calculations of the main design nodes such as a synchronous servomotor, ball screw, linear guide and bearing. The design itself was carried out with regard to calculations and the resulting model was examined in terms of dynamic stability. The subject of examination was to find the natural frequencies of

Abstract:

Abstract Diagnostics and prognostics of rotating machinery ball bearings is quite mature with an abundance of available methods and algorithms. However, extending these algorithms to other ball bearing applications is challenging and may not yield usable results. This work used a linear axis to study the ability of an inertial measurement unit (IMU), along with nine signal features, to measure changes in geometric error motions due to induced faults on the recirculating ball bearings of two carriage trucks. The IMU data was analyzed with the nine features used for rotating machinery systems, i

The present paper aims at determining the effect of several design and manufacturing parameters on the frictional response of the underhead contact in a bolted joint comprising a socket-head M6 class 12.9 screw. The rationale of the research moves from the need to understand the frictional behavior of screw joints used in machine tools as a means to join roller monoguides with the moving carriages of three-axis tooling units. The experimentation takes into account different underhead materials (Steel, Cast Iron, Aluminum), different roughness levels (Ra = 0.8, 1.6, 3.2), different surface trea
