    Abstract: According to the design plan of the camshaft for a 6-cylinder marine diesel engine, the torque of the camshaft assembly is verified. With CAE software, the assembling state of the camshaft assembly is simulated and analyzed to find out the weak design that appears in the thrust shaft. A related manufacturing techniques and measures are used to improve the camshaft for safe rotation.
