Block Lanczos Method

Modal analysis of crankshaft for two-stroke marine diesel engine is carried out on the block lanczos method. The finite element models of crankshaft is created in ANSYS. The crankshaft first 13 natural frequencies and mode shapes are shown as the result and lay the foundation for optimal design of the crankshaft and dynamic response.

Structural Redesign

In order to understand the dynamic characteristics of 16V240 type diesel, established its solid model and finite element model. And conduct the modal analysis of 16V240 diesel with Lanczos method to get the natural frequencies and vibration mode. And then, find the weak points of 16V240 diesel for its structural redesign and improving.
