The Dynamic Testing of Elastomers
نویسنده
چکیده
Elastomers are finding wider and wider applications throughout industry. For example, the automotive industry is continually attempting to improve fuel efficiency. The resulting reduction in body and engine weights put increasing pressure on suspension and sound insulation designers to meet the car buyers demands for improved ride quality and quiet cars. Designers are no longer satisfied with simple static performance data but need data that assists the design of complex systems involving elastomeric components.

Damping Behavior of the Phenolic Based Composite Friction Materials Containing Thermoplastic Elastomers (TPEs)
Attempts have been made for the first time to produce a friction material with thermal sensitive modulus by the inclusion of combined plastic/rubber properties of thermoplastic elastomers (TPE) as viscoelastic polymeric materials into the formulation for the purpose of increasing the damping behavior. In order to evaluate the viscoelastic parameters such as loss factor (tan δ) and elastic m...
متن کاملInfluences of NCO/OH and triol/diol Ratios on the Mechanical Properties of Nitro-HTPB Based Polyurethane Elastomers
The present study describes the effect of NCO/OH and triol/diol ratios on the mechanical properties of Nitro functionalized Hydroxyl-terminated polybutadiene (Nitro-HTPB) elastomers. The progress of the cure reaction of Nitro-HTPB and toluene diisocyanate (TDI) is evaluated by following up the variations in the IR absorption bands of the NCO stretching and the CO ...
متن کاملEvaluation of Dynamic Probing Testing Effect in Hand Excavated Pit on Test Results Using Numerical Modeling
In Iran, using the hand excavated pits (wells) have been more common compared to other countries. As a matter of fact, recent years, utilizing the dynamic probing test (DPT) in these types of pits has been significantly developed in Iran. This is while the standard state of doing this test is from the ground level. In this work, the dynamic probing test is carried out in two similar wells with ...
متن کاملModeling of a new semi-active/passive magnetorheological elastomer isolator
This paper presents theoretical modeling of a new magnetorheological elastomer (MRE) base isolator and its performance for vibration control. The elastomeric element of the traditional steel–rubber base isolator is modified to a composite layer of passive elastomer and MRE which makes the isolator controllable with respect to its stiffness and damping. The proposed variable stiffness and dampin...
