This study proposes a new design concerning a parallel compliant vibrating mechanism for high precision production lines and enforces dynamic simulating analysis. The conventional mechanism for separating fine particles has based on advantages of spring to make vibrating motion to separate out various particles with radius ranges from 7 mm to 20 mm. But it also has a few defects such as additional weights of the springs, the wear between the kinematic joints. To overcome these limitations, this paper applies the conception of compliant mechanism to design novel model. First, using the principle of compliant mechanism, a parallel compliant vibrating mechanism is developed. The use of ANSYS, finite element analysis (FEA) is performed to explore the results of dynamic analysis concerning both angular velocity of mechanism and both angular acceleration and both equivalent stress and total deformation of compliant segments. The results show that a proposed mechanism can be used in high precision manipulators, actuators, and production line chain. Future work will conclude an investigation into the vibration frequency.
