With the aim to find out the reason for rupture and inefficiency of Pelton turbine runner, a 3-D model for the runner and nozzle of Pelton turbine was established by UG software. The stress analysis of the running single bucket was conducted on by ANSYS software, and stress distribution and maximum stress value point were determined. The natural frequency and oscillation shape of the runner and nozzle of Pelton turbine were obtained by model analysis. The results provide references for the bucket strength design and the nozzle oscillation research of multi-nozzle and multi-bucket turbine runner.
