Aiming to study the effect of silicone oil viscosity on the properties of silicone oil based magnetorheological fluids (MRF), exper iment materials, preparation process and test methods are elaborated, and f ive kinds of MRF samples with different silicone oil viscosity are prepared T he microstructures of both carbonyl iron particles and coated carbonyl iron particles are observed by s canning electron microscope (SEM). Moreover, test experiments are carried out and the effect of silicone oil viscosity on sedimentation stability, zero field viscosity and shear yield stress is discussed. Experimental results show that the silicone oil vis cosity has a significant influence on sedimentation stability and zero field viscosity of MRF, but little impact on shear yield stress of MRF. Furthermore, the MRF with silicone oil viscosity 350cst and 500cst is best for the requirement of engineering app lications..

In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
