To further reveal the road performance and noise reduction of open-graded friction course (OGFC), crumb rubber prepared by adding waste tires were considered, requirements material put forward. avoid influence particle swelling on aggregate, special gradation mix proportion OGFC mixture designed, size 4.75 mm was proposed as control size. The test results show that aggregate forms a good embedd...

Manipulation of deformable objects will be discussed. Manipulation of deformable objects is de ned as controlling deformation of objects as well as their positions and orientations. The manipulation is a fundamental and important task in many industrial elds. In fact, there exist many operations of deformable objects such as textile fabrics, rubber parts, paper sheets, strings, and foods. In or...

The ingredients required for computationally e cient large-scale 3D FE contact analyses of automobile tires are presented. A hybrid nite element is employed for describing the nearly incompressible behaviour of rubber. The reinforcing cords are represented numerically by means of rebar elements. Strategies for reducing the amount of CPU time and disk space are reported including an iterative so...

A teletaction system uses a tactile display to present the user with information about texture, local shape, and/or local compliance. Current tactile displays are at and rigid, and require precise machining and assembly of many parts. This paper describes the fabrication and performance of a one-piece pneumaticallyactuated tactile display molded from silicone rubber. Tactor spacing is 2.5 mm wi...

The rubber-producing tree, Ficus elastica (the Indian rubber tree), requires the same substrates for rubber production as other rubber-producing plants, such as Hevea brasiliensis (the Brazilian or Para rubber tree), the major source of commercial natural rubber in the world, and Parthenium argentatum (guayule), a widely studied alternative for natural rubber production currently under commerci...

An artificial elastic finger for grasping an object, which we call an “artificial finger skin” is designed. Characteristics of the artificial finger skin are as follows: First, it has ridges at the surface and tactile sensors distributed underneath the ridges same as finger of human. Second, it has a curved surface in broad perspective. Third, it is made of an elastic silicone rubber so as to t...

Recently, several three-axial MEMS-based force sensors have been developed. This kind of force micro sensor is also called tactile sensor in literature for its similarities in size and sensitivity with human mechanoreceptors. Therefore, we believe these three-axial force sensors being able to analyse textures properties while sliding on a surface, as would do a person with his finger. In this p...

Unlike traditional pressure sensitive adhesives, the natural setal arrays of gecko lizards achieve dry adhesion with stiff, keratinous material. This remarkable property has inspired a new class of adhesive and high friction microstructures composed of stiff materials that, like natural setae, have an elastic modulus greater than 1 GPa. In contrast to softer materials, such as rubber and low mo...

This paper reports on the use of Zr-based (Zr53Cu33Al9Ta5) thin film metallic glass (TFMG) for the coating of syringe needles and compares the results with those obtained using titanium nitride and pure titanium coatings. TFMG coatings were shown to reduce insertion forces by ∼66% and retraction forces by ∼72%, when tested using polyurethane rubber block. The benefits of TFMG-coated needles wer...
