摘要
针对青城机械木工刨床吸尘能力不足的问题,选用其切屑作为研究对象,建立相应的三维模型,使用流体仿真的方法得到一定气流速度情况下在木材切屑上产生的作用力,并借助定向优化求解器得出在木材切屑上产生的作用力克服木屑重力时对应的气流速度和出口负压,根据仿真数据拟合得出气流速度与气流作用力的关系曲线。在产品设计和研发阶段,可以依据该气流速度判断整个木工刨床各结构是否产生木屑积累,为产品的结构设计提供一定的参考依据,也可以为提升产品的吸尘能力提供方向。
Aiming at the problem of insufficient chips absorption capacity of our woodworking planer,this paper selects its wood chips as the research object,establishes the corresponding three-dimensional model,uses the fluid simulation method to obtain the force generated on wood chips at a certain air velocity,and uses the direct optimization solver to obtain the corresponding air velocity and outlet negative pressure when the force generated on wood chips overcomes the gravity of wood chips.The relationship curve between air velocity and air force is fitted according to the simulation data.In the product design&research and development stage,the air flow speed can be used to determine whether the accumulation of wood chips is generated throughout the structure of the woodworking planer,which can provide a certain reference basis for the structural design of the product,and can also provide direction for improving the chips absorption capacity of the product.
