Modern mechanical design method is introduced to ensure the reliability, ease of use and economy of product design. Take the product function request as the design criterion, take the realization green energy conservation as the design goal, the beginning of autumn innovation, improves the product market competitiveness unceasingly.
Reliability analysis includes:
Strength and stiffness analysis of main components of steam turbine
Simulation and analysis of steam flow state of valve assembly and through-flow part
The intensity of blade
The finite element analysis of blades was carried out by using CAE software to verify the tensile strength, fatigue strength and blade root strength of blades, so as to ensure the safe operation of equipment.
Examples of dynamic blade root strength analysis
The strength and stiffness of the chassis directly affect the vibration characteristics of the unit. Sufficient stiffness can ensure the vibration value of the unit within the design range.
Critical speed analysis
The multi-order critical speed of rotor can be obtained by the multi-order frequency analysis of rotor assembly model, which provides theoretical reference for high-speed dynamic balance test of rotor.
Main valve strength analysis and flow simulation
Main valve shell is one of the important components of steam turbine, which is the key to the safe and stable operation of the unit. This analysis guarantees the design safety of main valve housing and adequate steam flow capacity.
