Thedevelopment of Unmanned Air Vehicles (UAVs) for both military and civilian applicationslead the opportunites for the development of advanced technologies to improve their operational performance. Due to various mission requirements UAVs will carry different types of payloads which change the total all-up weight. The landing gears of the UAVs should be optimized to the changing weights and va...

In an automotive system, the vehicle suspension usually contributes to the vehicle's handling and braking for good active safety and driving pleasure and keeps the vehicle occupants comfortable and reasonably well isolated from road noise, bumps and vibrations. The design of vehicle suspension systems is an active research field in automotive industry (Du and Zhang, 2007; Guglielmino, et al., 2...

Magnetorheological (MR) fluids are promising in controllable damping based on regulated apparent viscosity under magnetic field control, and they employed various devices such as automotive dampers energy absorbers for artillery or landing gears by medium substitution with structural adaptations. In this study, we designed fabricated a magnetorheological absorber (MREA) disc springs recoiling p...

The aggregation of magnetic particles in the presence of a magnetic field is the basic phenomenon which underlies all the physics of magnetorheological (MR) fluids. Although these interactions are well understood when the suspending fluid is a simple liquid, new MR fluids based on dispersion of magnetic microparticles in a ferrofluid or MR elastomers based on dispersion of magnetic particles in...

The dynamic response of railway bridges is important to consider, as the high velocity loading from trains increases risk resonance. Increasing train speeds and loads result in a need for adaptable properties bridges. One solution install magnetorheological dampers, structure originating moving could be controlled by alternating input current damper. However, complexity such devices results dif...

Increasing current vehicle development trends for small, light, front wheel drive vehicles with low idle speeds have been forced automotive industries to use hydraulic engine mounts for further improvement in vibration, noise and harshness (NVH) performance of the vehicles. However, with the development of modern vehicle designs such as hybrid vehicles and variable engine management systems whi...

In this study, the stability and rheological properties of a suspension of carbonyl iron microparticles (CIMs) in silicone oil were investigated within a temperature range of 10 to 85 °C. The effect of adding two hydrophobic (stearic and palmitic) acids on the stability and magnetorheological effect of a suspension of CIMs in silicone oil was studied. According to the results, for preparing a s...
