经纱张力调节机构的拓扑优化设计与疲劳分析

摘要/Abstract

摘要： 为提升经纱张力调节机构的动态补偿能力，适应三维间隔织物剑杆织机的高速化织造需要，引入可吸收应力的变刚度气动肌腱作为原动件，设计了一种新型经纱张力调节机构。采用有限元技术对该机构进行了静力学分析和模态分析，得到其静态特性及前六阶固有频率阵型，在此基础上采用变密度法对机构进行拓扑优化，随后根据优化结果在SW中进行结构优化并采用有限元仿真实验进行验证。结果表明：拓扑优化后的机构可以减重13.32%，同时应力、应变和固有频率等静动态性能均有较大提升，其最小疲劳寿命可达17.91年，满足织机使用年限的需要。最后在VSI系列样机上进行了对比实验，分析优化前后的张力采样曲线。实验结果表明优化后的织机经纱张力波动更加平稳，机构动态特性有效提升。

Abstract: In order to improve the dynamic compensation ability of the warp tension regulating mechanism and to meet the needs of high-speed weaving of three-dimensional spacer rapier loom, the variable stiffness pneumatic tendons which can absorb stress were introduced as the prime mover. A new type of warp tension regulating mechanism was designed, and its static characteristics and the first six natural frequencies were obtained by static and modal analysis with finite element technique. Then the topology of the mechanism was optimized by the variable density method, and the structure was optimized in SW according to the obtained results. The simulation results show that the weight loss is 13.32%, and the static and dynamic properties of the mechanism, such as stress, strain, and natural frequency, are greatly improved after topology optimization. Moreover, the fatigue life of the mechanism can reach 17.91 years, which meets the need of loom service life. At last, a comparative experiment was carried out on a series of VSI sample looms to analyze the tension sampling curves before and after the optimization. It is found that the tension fluctuation is more stable after the optimization and the dynamic characteristics of the mechanism are effectively improved after the topology optimization.
