Resilient rail fastening
|
A fastening that provides a degree of elasticity between the sleeper and rail with the aim of avoiding the loosening of the fastening due to vibration, as well as enhancing the ability of the fastening system to resist longitudinal creep forces and buckling forces associated with continuously welded rail (cwr).

Elasticity, английский
- Usually used to explain consumer demand in response to changes in prices. demand for basic goods such as bread is thought to be inelastic since the amount of bread bought changes little with price. if the price goes up, people have little choice but to pay it, but if it goes down they are unlikely to eat more bread. by comparison, luxury goods are price elastic. if the price of chauffeur-driven trips to work becomes too expensive, executives may switch to black cabs, or even the train.
- Упругость
- The property of a body that causes it to tend to return to its original shape after deformation (as stretching, compression, or torsion).
- The ability to expand and be compressed and to return to the former shape
- Способность к быстрой адаптации
- Упругость, эластичность bulk ~ объёмная упругость
- The ability of a strained material to recover its original size and shape immediately after removal of the stress that causes deformation.
- Responsiveness; the degree to which one variable (e.g., quantity demanded) is responsive to a change in another (e.g., price).
- The capability of a material to regain its original shape or
- Эластичность (цен, спроса, предложения)
- That property of a material by virtue of which it tends to recover its original size and shape after deformation. electrical noise
- Ability of a material to resume its former shape after deformation.
- Ability of a material to resume its former shape after deformation.1
- Ability of a material to regain its former shape after removal of applied stress. see also ductility.
Longitudinal, английский
- Generally parallel to the direction of the wood fibres.
- Продольный
- Generally, parallel to the direction of the wood fibers.
- Продольный, относящийся к долготе, стрингер
- [1] extending in the lengthwise direction, as distinguished from transverse. [2] said of any fore-and-aft structural member, such as a frame or bulkhead.
- Running lengthwise.
- Along the length of a structure.
- Direction parallel to the long axis of an object and perpendicular to its radius — for example, down the length of a cylinder. compare circumferential; radial; transverse. lot tolerance percent defective (ltpd): the poorest quality, in percent defective, individual lot that is acceptable in a sampling plan. ltpd is the percent defective that will be accepted by the sampling plan at most 10 percent of the time. with such a plan, the producer agrees to supply just enough nonconforming product such the consumer will accept the lot using the agreed to sampling plan and acceptable quality level. compare acceptable quality level. lumen (lm): si photometric unit of luminous flux, weighted according to the photopic vision response. one lumen equals the light emitted by one candela (cd) point source into one steradian (sr) solid angle (1 lm = 1 cd/sr).
Associated, английский
- Соответствующий; связанный; присоединенный
- Experiencing through your own senses (seeing through your own eyes, hearing with your own ears, feeling with your own feelings.)
Continuously, английский
Continuous, английский
- Непрерывный
- Непрерывный; длительный; продолжающийся
- A продолженный, дли- тельный, непрерванный form, future, past, present contoid n контоид
- Непрерывный, неразрывный, сплошной, неразрезной (об элементах конструкции)

Asbestos, английский
- A fibrous form of mineral silicates belonging to the serpentine and amphibole groups of rock forming minerals, including actinolite, amosite (brown asbestos), crocidolite (blue asbestos), chrysolite (white asbestos), tremolite, or any mixture containing one or more of these.
- Г. асбестос (пров. квебек, канада)
- Асбест
- Асбест. общее название класса природных волокнистых силикатов, которые широко используются для тепло-и электроизоляции, производства строительных материалов, тормозных колодок и многих других целей. существует два основных типа асбеста: хризотил (белый асбест), который наиболее широко распространен, и амфиболы, наиболее важными из которых являются крокидолит (голубой асбест), антофиллит и амозит. вдыхание асбестовой пыли может вызывать асбестоз (фиброзные разрастания легких) и повышение риска заболевания раком легких, причем степень риска зависит от многих факторов, в том числе от интенсивности и продолжительности воздействия, типа асбеста и длины волокон (длинные и тонкие волокна обусловливают более высокий риск). по данным, опубликованным международным агентством по изучению рака, болезнь может развиться спустя длительное время после воздействия (30 лет и более).
- A nonmetallic mineral fiber, which is nonflammable. the fiber is woven into fabrics and used for theater curtains and industrial uses where flame-resistant materials are needed.
Springspike, английский
A fastener used to attach sleeper plates to sleepers on clip fastened track. the spike comprises two leaves from one piece of spring steel, folded to produce a square shank and an eye.
