The constraint distribution in non-holonomic mechanics has a double role. On one hand, it is a kinematic constraint, that is, it is a restriction on the motion itself. On the other hand, it is also a restriction on the allowed variations when using D’Alembert’s Principle to derive the equations of motion. We will show that many systems of physical interest where D’Alembert’s Principle does not ...

While the heights and numbers of tires in the assembly line are changing, the traditional methods are difficult to identify the types of the tires, so an indirect tire identification method is proposed to identify the types of the tires, which uses the widths of the tires, the diameters and the shapes of the hubs to classify the tires. First, the tires are identified according to the widths and...

Event based sampling occurs when the time instants are measured everytime the amplitude passes certain pre-defined levels. This is in contrast with classical signal processing where the amplitude is measured at regular time intervals. The signal processing problem is to separate the signal component from noise in both amplitude and time domains. Event based sampling occurs in a variety of appli...

Between May 18 and December 4, 1986, 79 seagoing containers and their contents of 22,051 used tires were inspected for adult mosquitoes as well as eggs and larvae. Of the total inspected, 5,507 tires (25%) contained significant amounts of water. No adults or eggs were found. Fifteen tires contained mosquito larvae that were identified as Ae. albopictus, Ae. togoi, Culex pipiens complex, Tripter...

There was used example modern radial tires 360/70R24 Bel-89 18.4R34 F-11 agricultural tractor MTZ-1025.2. in modes non-nominal loading at nominal load changes tire pressure within range recommended field work. assess po...

Abstract The airless tires are developed to overcome a disadvantage of pneumatic tire which lost maneuverability caused flattening and blasting. finite element analysis (FEA) is an effective method for development have complex construction. material properties describe mechanical behavior each component very important yield accurate result. high order constitutive model usually obtains the accu...

Introduction . The most efficient machine for compacting road building materials in the construction of transport facilities, a roller with promising pneumatic tire that can effectively use vibration, is considered. Materials and methods results studies characterizing parameters imprint contact working body supporting surface, which significantly affect efficiency technological operation materi...
