为了研究切割片在工作过程中的振动及噪声问题,基于有限元方法,借助于ANSYS APDL有限元软件建立了切割片有限元模型;采用反转法施加载荷,简化模型及分析过程,在振动特性分析中,得出调整切割片结构参数可以降低切割片振动幅度的结论;基于振动能量与速度的平方关系,以测试点的速度平方和为目标函数,设计了优化程序对切割片模型进行调整优化,获得了一组最优调整数据,为实际生产提供了参考依据。
To reduce vibration and noise of the cutting blade in working process, a finite element model of the cutting blade was established by ANSYS APDL. Load was given by inversions to simplify the model and analysis the process, and the results show that the vibration amplitude of the cutting blade can be reduced by rectifying the parameters. Based on the square relationship between the vibration energy and the velocity, we designed an optimization program by taking the quadratic sum of the speed of the test point as the objective function to optimize the cutting blade model, and acquire a set of optimized data, which can provide basis for actual production.
