Double slip turnout is common in heavy haul railway and due to its complex structure, its maintenance is difficult as well as important. Focusing on No.12 double slip turnout (75 kg/m rail), this study analyzed the intensity of the different slotted rubber pad under iron plate and track stiffness of turnout zone based on the finite element method with a purpose of improving the performance of t...

535] A new and unique building vibration isolation pad has been developed utilizing alternating layers of elastomer and carbon fiber mesh. The carbon mesh reinforcement provides several distinct advantages over traditional steel plate reinforcement. Lower natural frequencies and/or smaller operating heights can be obtained for a given load. In addition, the carbon mesh forms both chemical and m...

We present a new haptic augmented reality system that modulates the perceived stiffness of a real object by changing the perceived material with vibratory subtraction and addition. Our system consists of a stick with a vibrotactile actuator and a pad with an elastic sheet. When a user taps the pad, the innate vibration resulting from the tapping is absorbed by the elastic surface. Simultaneousl...

Abstract Due to the change from mass production personalized and resulting intrinsic product flexibility, automotive industry, among others, is looking for cost-efficient resource-saving methods combining global just-in-time production. In addition geometric manufacturing additive offers a application rapid prototyping small series in predevelopment. this study, FDM process utilized manufacture...

Flexible forming is a sheet metal forming process with the application of soft material tooling. In this study, flexible (silicone rubber, SR, and styrene butadiene rubber, SBR) and semi-rigid (polyamide 66, PA) polymeric materials were adopted to make several upper dies which were used in combination with aluminium lower dies. Stamping operations were performed on a thin aluminium alloy sheet ...

We propose a new method for estimating the contact state of objects with varying shapes on a vision‐ based fluid‐type tactile sensor, which touch pad is an elastic transparent membrane of silicon rubber with dotted pattern printed on its inner side. The membrane is filled with translucent red colored water. The proposed method leads to better understanding of the...

Due to geographic and climatic conditions in mountainous northwest area, Roads in these areas are often covered with snow, ice and mud. Hence Transportation of equipment and soldiers encounter hardship and difficulties in rural area and specially outposts. To solve these problems, it is needed to fabricate portable roadway or traction mats. These high strength mats cover surface of roads and ar...

Reconfigurable multipoint forming is a flexible sheet technique aimed at customised metal products. However, one drawback of the cost and time needed to set up align upper lower pin matrices. This study introduces an optimisation novel hole-type rubber punch replacing top matrix incremental forming, aiming reduce pins setting alignment complexity time. Finite element modelling design experiment...
