摘要
将车架作为线性系统处理,计算出输入激励为余弦波形时,车架在不同频率下的位移和应力响应,并绘制结构动态响应与频率的关系曲线;根据分析结果可预测结构的持续动力特性,避免系统发生共振、疲劳及其他由受迫振动产生的有害影响。
The frame is approximated as a linear system. When input excitation is cosine waveform, displacement and stress response of the frame in different frequency are calculated, and the curve of the structural dynamic response versus frequency is drawn. According to the results obtained, continuing dynamic characteristics of the structure can be predicted, which will be beneficial for avoiding the system resonance, fatigue, and other harmful effects produced by forced vibration.
