Numerical Simulation of High-performance Lip Seal for Ultra Large Offshore Wind Power Equipment
摘要
Abstract
Taking the high performance and long lifespan lip sealing interface of offshore wind power gearbox as the research object,combined with its application conditions and its own structure,the static eccentricity caused by assembly errors and component tolerances of the sealing system is considered.A numerical simulation analysis model is established which comprehensively considers the coupling of multiple physical fields such as interface fluid mechanics,macroscopic solid mechanics and surface microscopic contact mechanics under the actual service condition of the sealing system.The rationality of the finite element simulation model is verified by using a radial force tester.The leakage rate of dangerous cross section and friction torque are taken as evaluation indexes.The influence of static eccentricity of the wind-electric"main drive chain"on the performance of rotary oil seal under bad sea conditions is studied.The results show that the static eccentricity can change the contact state of the lip,which has a great impact on the sealing performance.The study has a guiding significance for the sealing and anti-leakage design and application of ultra-large offshore wind power equipment.关键词
