Designing Bonded Cylindrical Joints for Automotive Applications

Anaerobic adhesives are now being used in more demanding load bearing cylindrical joint applications. The key to the success of such applications is to combine the adhesive with a reduced interference fit and still achieve high static and dynamic torsional strength. To develop such applications required a strength prediction method to aid in the design process. An empirically based PC software package was developed and has enabled assessment of the feasibility of a proposed joint design before the prototype testing stage. This approach is demonstrated through the development of several recent automotive applications including driveline gear bonding.
