| Abstract:The design and check of tie rod on a new low‐speed marine diesel engine was carried out.The initial design of the tie rod was completed according to the performance parameters of the diesel engine and the dimensional parameters of cylinder components，and the static strength stress and dynamic fatigue strength of the tie rod were evaluated through the static strength check and dynamic fatigue analysis respectively，so as to check the safety margin of the tie rod design，thus provide a basis for the design of the tie rod of the low‐speed engine. |
| Key words: low speed diesel engine tie rod dynamic load fatigue strength |
