碳纤维立体织机打纬机构运动特性仿真

Kinematics simulation in carbon fiber multilayer loombeating-up mechanism

针对现有碳纤维立体织机打纬机构打纬力不足的弊端,提出利用矢量法来分析,并在Simulink环境下采用不同输入信号将对心式和偏置式曲柄滑块打纬机构进行运动学仿真对比分析,得到了2种情况下滑块的运动曲线.实验结果表明:当曲柄输入状态为匀角速度时,采用偏置式曲柄滑块打纬机构不仅满足织机所需的运动规律,而且相较于对心式机构更能满足织机对打纬力的要求。

Aiming at the disadvantages of the existing carbon fiber three-dimensional loom beating-up mechanism of beating up force being insufficient, the vector method is proposed, and using different input signals of heart type and offset slipscrank beating up mechanism kinematic analysis of simulation under Simulink environment, the motion curve under the two conditions of the slider are obtained. The experimental results show that when the crank input state for uniform angular velocity, slipscrank beating up mechanism can meet the desired motion of the loom, compared to the heart of mechanism, can also meet the requirements of loom beating up force.
