| 1、建立有限元模型 1. Establish a finite element model 外形基本尺寸：滚筒直径D=1000mm，筒体宽度L=1600mm，与胀套结合处轴直径为320mm。本文采用三维设计软件Solidworks，分别对滚筒、接盘、胀套和轴建立基本模型，通过特有的装配关系把他们装配到一个新的装配体中，微型电动滚筒报价，通过这种方法，得到所需要的力学模型。在建模过程中，我们适当的采取简化措施。本文在建立滚筒模型时对其简化方法如下： The basic dimension of the shape: the diameter of the cylinder D=1000mm, the width of the cylinder L=1600mm, and the shaft diameter of the joint with the expansion sleeve is 320mm. This paper adopts the three-dimensional design software Solidworks respectively on the roller plate, expanding sleeve and shaft to establish the basic model, the assembly relationship unique to their assembly to a new assembly, micro electric drum offer, through this method, get the required mechanical model. In the process of modeling, we appropriately take the simplification measures. In this paper, the simplification method of the drum model is as follows: （1）略去了滚筒轴的所有倒角。（2）不考虑滚筒包胶与传动滚筒之间的相互作用，微型电动滚筒，直接将滚筒质量等效到筒壳上。（3）略去次要构件，将轴承座简化为对轴的约束。（4）由于滚筒为对称结构，取1/2滚筒建立有限元模型，这样可以节省设计时间和费用。做了上述简化之后导入ANSYS中，建立几何模型。 (1) all the chamfering of the roller shaft is omitted. (2) the interaction between the drum and the drive roller is not considered, and the micro electric roller is directly equivalent to the cylinder's shell. (3) a minor component is omitted and the bearing seat is simplified as a constraint on the axis. (4) because the cylinder is a symmetric structure, the finite element model is established by taking the 1/2 drum, which can save the design time and cost. After doing the above simplification, it is introduced into the ANSYS and the geometric model is established. 2、材料的属性 2. Properties of materials 在进行有限元分析前，必须输入滚筒材料的相关属性。 Before the finite element analysis is carried out, the related properties of the roller material must be input. 我们知道外装式电动滚筒采用谐波齿轮传动机构时，微型电动滚筒生产厂家，由于啮合原理的不同，其效率计算和齿面润滑状态分析与其它齿轮传动也不相同。刚性构件齿轮传动，通常采用弹性流体动压润滑理论分析（即摩擦体表面的弹性变形和润滑液体的压力- 粘度效应，对润滑膜厚度和压力分布起显著影响的流体动压润滑。滚动轴承、齿轮传动和凸轮机构等点、线接触的摩擦副在一定条件下都有可能形成弹性流体动压润滑。），而对于谐波齿轮传动，轮齿工作时很接近面接触，微型电动滚筒厂商，采用流体动压润滑理论分析（即流体动压润滑是依靠运动副两个滑动表面的形状，在其相对运动时，形成产生动压效应的流体膜，从而将运动表面分隔开的润滑状态。）。 We know that when the external electric roller adopts harmonic gear transmission mechanism, because of the difference of meshing theory, the efficiency calculation and the lubrication analysis of the micro electric roller manufacturer are different from those of other electric gear trains. Rigid body gear transmission is usually analyzed by elastohydrodynamic lubrication theory, that is, the elastic deformation of the friction surface and the pressure viscosity effect of the lubrication fluid, which significantly influence the lubrication thickness and pressure distribution of the hydrodynamic lubrication. The friction pairs of rolling bearings, gear drives and cam mechanisms are likely to form elastohydrodynamic lubrication under certain conditions. However, for the harmonic gear drive, the work is very close to the tooth surface contact, micro electric drum manufacturers, by analysis of hydrodynamic pressure lubrication theory (i.e. hydrodynamic lubrication is to rely on the motion of the two sliding surfaces in the shape of its relative movement, the formation of dynamic fluid film pressure effect which will lubrication. The moving surface separated). |
