Plus-sizing, or the fitting of larger diameter rims and lower profile tires to vehicles, continues to be a significant commercial force in the tire marketplace. When offering plus-size fitments to customers, many sellers simply offer “what fits” on a given vehicle. However, the various choices made by the seller, such as wheel width, wheel offset, inflation pressure, and so on, have the potenti...

tillage and press wheel weight play an important role in seedling emergence, crop establishment and growth. an optimal combination of tillage implements and suitable press wheel weights should increase grain yield. this study investigated the effect of tillage systems and press wheel weights on dry land wheat (triticum aestivum l.) seedling emergence and grain yields in izeh, khuzestan province...

Desiccant wheels are widely used in buildings to control humidity and reduce energy consumption. A model is presented based on transient coupled heat and mass transfer, to model, design and analyze the effects of geometrical characteristics of a honeycombed rotary desiccant wheel and its performance. Governing equations are solved numerically using finite volume method and the model is validate...

in this study, the effect of furrow firming rollers were investigated to improve furrow irrigation parameters such as: advance time, runoff, deep percolation and irrigation efficiency (application efficiency) in the roller treatments, nonroller treatments (traditional) and treatment of including compacted with tractor wheel in the miandab agriculctural station in west azerbaijan during 2001-200...

plicated processes on the wheel surf ace along the wheel width. In order to make these processes clear, the experimental analysis of traverse grinding was conducted by widely changing the speed ratio, Kv, the setting depth of wheel, ‡TMT, and the number of total steps, m, (the ratio of the wheel width over the traverse feed per one revolution of the workpiece). The following results were obtain...

With the development of space science and technology, some countries have launched unmanned planetary exploration programs. Because planet surfaces are rough and formidable, planetary exploration rovers were used as a versatile and safe alternative to manned space missions to explore the planets. In recent years, many types of planetary rovers were developed including tracked type, legged type,...

In this paper, multi-objective optimization of railway wheel web profile using bidirectional evolutionary structural optimization (BESO) algorithm is investigated. Using a finite element software, static analysis of the wheel based on a standard load case, and its modal analysis for finding the fundamental natural frequency is performed. The von Mises stress and critical frequency as the proble...

The roll center is one of the key parameters for designing a suspension. Several driving characteristics are affected significantly by the migration of the roll center during the suspension’s motion. The strut/SLA (strut/short-long-arm) suspension, which is widely used in production cars, combines the space-saving characteristics of a MacPherson strut suspension with some of the preferred handl...
