摘要
固有频率是摩托车车架的重要动态特性之一。通过模拟实际情况对车架模型进行了简化,同时施加了约束。通过对理论模态和实验模态分析结果进行对比,说明理论分析时对车架进行适当简化是合理的,约束是有效的。
Nature frequency is one of the most important dynamic characteristics of motorcycle frame,which can be acquired by using experimental modal analysis and mathematical modal analysis.According to the real situation,a simplified model was developed and constrains were loaded,and the theoretical values were obtained.With the aided of computer,a group of experimental nature frequencies and vibration modes were acquired.Comparison between two groups of results indicates that the simplified method in this paper is correct and constrains are effective.
