| Abstract: | Basic principles of Test modal analysis are outlined, and discreted mathematical model for diesel cylinder extablished. Dynamic damped response of cylinder block under actual operating condition is calculated on mode supperposition principle. Based on above analysis, the cylinder is modified with satisfactory results obtained. |
