摘要 综框是重要的纺织机械专用基础件。以230 cm幅宽综框为依据,利用APDL语言设计开发了传统材质综框和复合材料形态综框的建模程序。在此基础上,计算、分析和比较了木质、铁质、铝合金综框与碳纤维复合材料综框的固有频率及振动模式,并通过谐振响应分析获得了 X、Y、Z 方向的幅频响应曲线,确定了对综框危害较大的谐振频率及响应方向。结果表明:碳纤维复合材料综框的连续安全频率区间(0~87 Hz)明显高于传统综框,具有更优的动力学特性。验证了新型复合材料综框在动力学层面的先进性,为综框专用件的实践选型和织机系统的减振降噪提供了重要参考。 Heald frame is an important basic component for textile machinery. Based on 230cm-wide heald frame, the modeling program of heald frame made of traditional material and heald frame made of composites were designed and developed by APDL language. On this basis, the natural frequencies and vibration modes of wood, iron and aluminum alloy heald frame and heald frame made of carbon fiber composite were calculated, analyzed and compared. Besides, the amplitude-frequency response curves on X, Y and Z directions were obtained by resonance response analysis, and then resonance frequencies and response directions which harm the heald frame were determined. Study results indicate that, the continuous safe frequency range (0~87 Hz) of heddle frame made of carbon fiber composite is obviously higher than that of traditional heddle frame, and thus it has better dynamic characteristics. The study verifies the advancement of new composite heald frame at the dynamic level, and then provides an important reference for practical selection of special heald frame parts and vibration and noise reduction of loom system.
