摘要
制动盘在旋转时容易发生变形,易引起共振,应该对上述情况进行校核。使用有限元方法对某制动盘分别进行静力学和模态分析,分别得到了该制动盘在800/min时的变形量和应力,前4阶固有频率以及对应的临界转速。计算结果表明,该制动盘有较好的强度和刚度,额定转速远低于最小临界转速。
In order to verify the strength of brake disk shaft at high speed , static and modal analysis is carried out by using FEM. Displacement and stress are obtained from the analysis when the speed is 800r/min.the The free frequency and critical speed are also obtained. The conclusion is that brake disk has enough strength and stiffness, and the rated speed is much lower than the critical speed.
