| 针对国产带锯床设计中，普遍存在的锯架设计不合理导致锯条寿命短、锯切精度及效率不迭标、制造成本高等问
题，建立了带锯床锯架力学模型；以某型号锯床为实例，根据锯架力学模型对锯条进行了应力循环分析，建立了锯条的疲
劳分析模型；并以疲劳分析结果作为锯架改进设计的基础，得出了改进后详细的锯架设计参数。结果表明：改进后，带锯
条受力满足疲劳强度要求，很大程度上提高了锯条寿命及锯切精度。文中所建立的锯架力学模型适用广泛，具有较高的
实际应用价值。 |
| 英文摘要: |
| Aiming at the problem of the unreasonable design of saw frame causing the low service life, the substandard
cutting precision and efficiency, high manufacturing cost, the mechanical model of saw frame was proposed. According
to the mechanical model, the analysis of stress cycle was carried out, and the analysis model of blade fatigue was created
about a type of band sawing machine. The improved design of saw frame was based on the fatigue analysis results, and
the detailed design parameters about saw frame were given. The results indicated that after the improved design, the saw
blade force meets the fatigue strength requirements, the service life of saw blade and the cutting precision increased. The
mechanical model obtains higher value of application, and it can be applied to all kinds of band sawing machine. |
