ANSYS in Marine

Problem

Simulate coupling bolts on a marine shafting system from an engine to a propeller

Solution

ANSYS is used to show fretting trends through micro-slip of the relevant surfaces of the bolt.

Result

Designs are optimized for fatigue lifetime and ease of bolt extraction.

ANSYS analyzes a flanged shrink fit bolts stress under torque and thrust during operation of a Marine propeller shaft. This is particularly useful during dry-dock operations and inspections during shaft withdraws.
