Rotaxanes. In their Research Article (e202303341), Toshikazu Takata et al. investigate the effect of axle end structure and number through-space bonds on properties rotaxane crosslinked polymers.

One of the ways to increase maneuverability wheeled vehicles National Guard Ukraine is use a four-axle chassis with two turntables, which will allow machine turn smallest radius, move crab, sideways and around its own vertical axis. The creation such associated large amount various experiments tests finished sample. development computer technology technologies has led software applications for ...

The use of axle counters makes it possible to automate the processes station car model formation and renewal. existing approaches define installation sites for at necks, fixed by regulatory documentation, are in location counting points next all insulating joints track chains that leads equipment redundancy. At same time, application qua only control device freedom faces a number obstacles amon...

In order to calculate the vehicle load model of Baijianhe Bridge, based on data health monitoring system, type, weight, wheelbase, and other information were counted processed diagraphed obtain probability density distribution. At same time, automobile parameters relative national current code finite element method are calculated. The results show that 2-axle 6-axle vehicles main types, account...

A recursive non-linear model was developed for the prediction of pavement performance as a function of traffic characteristics, pavement structural properties and environmental conditions. The model highlights some of the advantages of relaxing the linear restriction that is usually placed on the specification form of pavement performance models. First, a functional form that better represents ...

Tractor overturning remains a serious problem in agricultural activities. A detailed analysis of problems and causes leading to a tractor overturn have revealed that by improving tractor’s static stability we can positively infl uence the safety as early as during the concept phase. We designed a mathematical model and a numerical simulation of the static stability of a tractor with an oscillat...

Whole body vibration (WBV) exposure is recognised as a risk factor to the high prevalence of spinal musculoskeletal disorders (MSDs) experienced by farmers. The purpose of this study was to identify self-reported predictors that could be used to develop statistical models for WBV exposure (expressed as A8rms and VDV) in farmers operating agricultural quad bikes. Data were collected in the field...

Railways, like a lot of industries are becoming increasingly reliant on programmable technology for safety. The development of railway technology is however largely driven through market forces and, given the complexity and cost of developing and certifying safety-related systems, rail industry suppliers tend to accede to the needs of their bigger customers. Consequently the in-built functional...
