Abstract:

The macroscale simulation methods are commonly used to study the wear of reciprocating seals to analyze macroscopic effects on the seal wear. There is a lack of numerical method for analyzing the wear of reciprocating seal under mixed lubricating conditions. According to experimental studies, some microscopic factors, including lubrication characteristics and surface roughness, are important for wear of reciprocating seal. Hence, in the presented research, a numerical model is proposed to analyze the effects of microscopic factors on reciprocating rod stepseal wear. O-ring of the stepseal is c

Abstract:

With the development of rolling linear guide manufacturing, improvements of performance and reliability of rolling linear guide products have become the critical technical challenge. One of the key-points lies in the analysis of wear process, in which the crucial step depends on the computation of the wear coefficient. However, little attention has been devoted to the wear coefficient of rolling linear guide. Therefore, in this article, to reflect the actual working condition of rolling linear guide, a novel calculation model for the wear coefficient of rolling linear guide is established firs

The article is devoted to improving the method of testing the wear resistance of “block-on-ring” friction pairs.

The effect of load on linear reciprocating sliding friction and wear behavior in a Zr55Cu30Ni5Al10 bulk metallic glass was investigated.

The larger the load is, the more serious the wear extent exhibits. Under smaller loads, the wear mechanism inclines to a combined result of slight bite or bite welding and continuous wear.

The results show that textured surface shows less wear rate on comparing with non-textured surface even during high temperature and high load conditions.

Tooth wear is a multifactorial condition leading to the irreversible loss of dental hard tissues. Although tooth wear is mainly a physiological process, it can become pathological if the wear process is accelerated for various reasons. Since this process is not linear, but can sometimes be inactive and sometimes active, a careful monitoring policy is necessary. The possible monitoring tools are described in this article, and a proposal is made with regard to the frequency of the systematic and periodic collection of information.

The local linear embedding algorithm makes high dimensional information down to low dimension feature space through commutation, and thus to compress the data for highlighting signal features. This algorithm well compensates for the weakness of linear dimension reduction failing to find datasets nonlinear structure. In this paper, acoustic emission signal is firstly made by phase space reconstruction.

The thermoplastic materials studied are biphasic. They consist of a polymer mass and a short glass fiber, the percentage being between 10 and 30%. We have shown, both analytically and graphically, the evolution of wear occurring on the steel surface in contact with glass fiber-reinforced polymers. The evolution in time of this process depends on the evolution of the friction coefficient in the process of the dry linear contact between different polymers and different types of steels. We have made a connection between the theoretical case and the experimental results. The experimental method us

Abstract:

Results of comparative research of wear resistance of polytetrafluoroethylene (PTFE), polyetheretherketone (PEEK), ultrahigh molecular weight polyethylene (UHMWPE) and polyamide 6 (PA6) in friction pairs with 18Kh2N4МА, 08Kh18N10Т and 40Kh13 are presented. Self-lubricating ability of polymers was determined by the contact pressure value corresponding to the upper border of the diapason, in which the effect of stabilization of linear wear intensity values and by the length of this diapason along the axis of loads is shown. Carbon steel 45 was used as a base steel in the comparison. PEEK, UHMWPE

Abstract:

Background: The occurrence of multi-directional sliding motion between total knee replacement bearing surfaces is theorized to be a primary wear and failure mechanism of ultra-high molecular weight poly(ethylene) (UHMWPE). To better quantify the tribologic mechanisms of this cross-shear wear, the MAX-Shear wear-testing system was developed to evaluate candidate biomaterials under controlled conditions of cross-shear wear. Method of approach: A computer controlled traveling x-y stage under a 3 degree-of-freedom statically loaded pin is used to implement the complex multi-directional motion path

Abstract:

The wear resistance of electroplated nanostructured and amorphous nickel phosphorus alloy coatings was studied using pin-on-disc dry sliding wear testing. The wear rate was measured using volume loss as determined by different calculation methods, worn track, and mass loss. Unexpectedly, a linear relationship between hardness and wear resistance was not observed.

Abstract:

This article presents a novel linear actuated chain test rig, which is capable of accelerated test speeds and continuous wear measurements. The ability to measure chain wear in situ saves time and expense compared to a conventional sprocket driven rig because the traditional rig requires the chain to be dismantled in order to monitor wear. In situ chain measurement reduces errors significantly. The novel test rig does not have a traditional set up of rotary driven sprocket and chain but uses a pneumatic linear actuator to articulate a short section of chain, which is preloaded between two cant

Abstract:

An on-line system for drill wear detection has been developed by using a sensor fusion strategy. Both acceleration and thrust signals were analyzed. Flank wear area was used to evaluate drill wear states. The drill wear area was measured by a vision system and classified into two groups: usable and worn-out. The wear prediction model was obtained by a two-category linear classifier. On-line detection tests indicate that the prediction model has over a 90 percent success rate.

Abstract:

Mechanistic cutting force model has the potential for monitoring micro-milling tool wear. However, the existing studies mainly consider the linear cutting force model, and they are incompetent to monitor the micro-milling tool wear which has a significant nonlinear effect on the cutting force due to the cutting-edge radius size effect. In this study, a nonlinear mechanistic cutting force model considering the comprehensive effect of cutting-edge radius and tool wear on the micro-milling force is constructed for micro-milling tool wear monitoring.

Given this basis, it does not only assist the selection of reasonable cutting tool but also enable the detection of the patterns in the cutti

SUMMARY A laboratory study was conducted to examine the wear of resin composite materials using a generalized wear simulation model. Ten specimens each of five resin composites (Esthet•X [EX], Filtek Supreme Plus [SP], Filtek Z250 [Z2], Tetric EvoCeram [EC], and Z100 Restorative [Z1]) were subjected to wear challenges of 100,000, 400,000, 800,000, and 1,200,000 cycles. The materials were placed in cylinder-shaped stainless-steel fixtures, and wear was generated using a flat stainless-steel antagonist in a slurry of polymethylmethacrylate beads.

The Reynolds equations governing the flow of lubricant in the clearance space of a hydrodynamic journal bearing system with varying wear depth has been numerically solved using Galerkin’s FEM. The regime is assumed to be isothermal. The positive pressure zone is established using Reynolds boundary condition through iteratively. The vario

Abstract:

We consider fretting wear due to superimposed normal and tangential oscillations of two contacting bodies, one of which is an elastomer with a linear rheology. Similarly to the contact of elastic bodies, at small oscillation amplitudes, the wear occurs only in a circular slip zone at the border of the contact area and the wear profile tends to a limiting form, in which no further wear occurs. It is shown that under assumption of a constant coefficient of friction at the contact interface, the limiting form of the wear profile does depend neither on the particular wear criterion nor on the rheo
