This is a study for the deformation and contact pressure of the squeezing roller used in the sizing processing industry. The deformation(roller bending) of a squeezing roller will affect the fiber property, the squeezing roller design insuring uniform contact pressure is very important. The improved squeezing roller model was obtained by changing the roller diameter, coating rubber thickness, sizing roller length and sizing roller support plate gap. As a result, the design parameters at which the deformation(roller bending) of roller was nearly uniform was found.

Since the knuckle, a core component for automobile suspension, directly supports the wheel, it needs strength and durability. Studies for improving durability of the knuckle have been done but most of them are focusing on knuckle for hollow type shape. The durability test has been conducted under a driving condition of lateral force mode, braking torque mode and steering input mode by using hydraulic actuator for spindle type steering knuckle of independent suspension applied for commercial vehicles. We’ve also carried out structural analysis and fatigue analysis by utilizing MSC.Patran, MSC.Nastran and MSC.Fatigue in order to compensate for weak parts of the knuckle upon the result of the test.
