ABSTRACT:
A method of designing a hard disk drive suspension swage hub geometry for an actuator arm having upper and lower suspensions attached thereto, includes using a finite element analysis model to simulate the effects of swaging the suspensions to the actuator arm, identifying relevant geometric parameters of the suspensions, for each suspensions performing a linear regression to fit an equation containing the geometric parameters to a normal force of the suspension to the actuator arm after swaging according to the fine element analysis, identifying a desired range of differences between the normal forces, using the desired difference range, and solving for values of geometric parameters to produce a set of target design parameters for the suspension swage hubs.
