| 中文摘要: |
| 采用ANSYS有限元分析软件，通过模态分析和谐响应分析，对1665型双模定型硫化机全焊接横梁的振动时效工艺关键参数（激振力、激振频率及激振点等）进行预测。由模态分析可知，横梁前10阶振动4个优选固有频率中318 Hz的波浪振型较为合理，并据此确定其激振点。通过谐响应分析获得一定激振频率、不同激振力时横梁所受最大动应力分布，并根据国家标准确定激振力取值范围为［300，690］ kN。 |
| 英文摘要: |
| The key parameters (exciting force,exciting frequency,and exciting point) of vibratory stress relief process for all-welded beam of 1665 dual-mould shaping press were predicted with modal and harmonic response analysis by ANSYS finite element analysis software.The modal analysis indicated that the wave vibration at 318 Hz was a typical mode in the four preferential natural frequencies among front ten steps,and the exciting point was determined by this vibration type.The distribution of maximum dynamic stress distribution was then obtained according to different exciting forces in certain exciting frequency by harmonic response analysis,and the range of exciting force was from 300 to 690 kN based on the national standard. |
