Monorail Truss Structure Selection Based on Modal Analysis

摘要：

　　The monorail truss structure natural vibration characteristics affect the performance of monorail in the work, this paper apply finite element method to carry out monorail truss natural vibration characteristics research.Considering the engineering practice, research and development two groups of monorail truss structure, calculated strength for two kinds of structural, two groups of truss structure strength meet the requirements, then used Guyan reduction theory to carry out modal analysis for the two trusses.From the modal analysis result can be found that the two groups of truss each order natural vibration period are not significant, structure natural frequency is intensive distribution, truss 2 dynamic rigidity is better, so was selected as the final structure scheme.The design ideas and methods provide a useful reference.
