在完成连续波脉冲器减速器的初步设计后,需要对其进行分析和仿真,验证设计是否合理。利用SolidWorks软件建立减速器三维模型,运用有限元分析软件Simulation模拟减速器的实际工作状态,分析太阳轮的强度和疲劳,可以计算出太阳轮的安全性和寿命周期。利用运动分析软件Motion模拟减速器运动状态,可以计算出输入扭矩与功率等数据,随后与设计参数对比,检验设计参数是否合理。对减速器进行运动仿真,仿真结果与设计参数一致,说明设计能够满足使用要求。 相似文献

减速器作为应用最为广泛的机械设备已形成了系列化产品,但其设计过程存在很大的重复性劳动,所以对结构相似的减速器进行参数化变型模板的设计显得尤为重要。利用自顶向下的设计理念和参数化设计技术,以顶级布局结构为产品的设计基础,在三维设计软件UG/NX的平台下实现了二级圆柱齿轮减速器参数化变型模板的设计。应用该模板可以进行同系列减速器的快速变型设计,明显提高设计效率,实现产品级模型的重用。该参数化变型模板的设计方法对其他产品模板的设计工作有普遍的适用性。 相似文献

In a recent paper, the Ritz method with simple algebraic polynomials as trial functions was used to obtain an eigenvalue equation for the free vibration of a class of homogeneous solids with cavities. The method presented is here extended to the study of a class of non-homogeneous solids, in which each solid is composed of a number of isotropic layers with different material properties. The Cartesian coordinate system is used to describe the geometry of the solid which is modelled by means of a segment bounded by the yz, zx and xy orthogonal coordinate planes and by two curved surfaces which are defined by fairly general polynomial expressions in the coordinates x, y and z. The surface representing the interface between two material layers in the solid is also described by a polynomial expression in the coordinates x, y and z. In order to demonstrate the accuracy of the approach, natural frequencies are given for both a two- and three-layered spherical shell and for a homogeneous hollow cylinder, as computed using the present approach, and are compared with those obtained using an exact solution. Results are then given for a number of two- and three-layered cylinders and, to demonstrate the versatility of the approach, natural frequencies are given for a five-layered cantilevered beam with a central circular hole as well as for a number of composite solids of more general shape. 相似文献

Polyvinyl pyrrolidone-Iodine complex (PVP-I) molecules were impregnated into the anodic oxide of an aluminum disk specimen. It was rubbed against a silicon nitride ball specimen using a ball-on-disk type friction test rig. Over the limited range of parameters studied (load: 0.2-1.0 N, sliding velocity: 0.6 mm/s, and sliding distance: 1-7 m), the coefficient of friction decreased to a value as low as 0.01 from values of 0.3 to 0.7 for the anodic oxide surface. Single-crystal iodine rubbed against silicon nitride showed a coefficient of friction of 0.1. The low coefficient of friction is attributed to the thin PVP-I film on the relatively hard anodic oxide. The mechanism of coefficient of friction reduction is the same as that of a thin soft film on a hard substrate. 相似文献
