【摘要】 应用虚拟样机技术这一种崭新的产品开发方法,可以在制造物理样机之前通过虚拟样机来方便地修改设计。采用虚拟样机代替物理样机对产品进行创新设计、测试和评估,可以缩短产品开发周期,降低产品开发成本,改进产品设计质量,提高面向客户与市场需求的能力,并加快新技术向新产品的转化。虚拟样机技术的应用己成为机械行业在产品设计中的发展方向。本论文以某企业矿用掘进机行走减速器为研究对象,利用三维造型软件UG、虚拟样机分析软件ADAMS、RecurDyn以及有限元分析软件ANSYS,对掘进机行走减速器进行了实体建模、动态仿真和有限元分析。本论文基于虚拟样机技术,结合CAD/CAE软件,在矿用减速器的仿真分析方面,做了如下工作:1.掘进机行走减速器的实体模型的构建。基于三维设计软件UG的建模功能精确构建了齿轮的三维模型以及其他零件如:轴(齿轮轴)、轴承、箱体等,并通过UG的装配模块,实现了行走减速器的虚拟装配和干涉分析。2.构建了减速器虚拟样机模型。将UG模型通过Parasolid数据格式导入到ADAMS中。在ADAMS中,添加系统约束、载荷以及驱动,建立了虚拟样机模型,并通过对样机的运动学仿真对样机进行了验证。3.掘进机简化模型的行驶仿真。基于韩国动力学分析软件RecurDyn,建立了掘进机的简化模型,并对简化模型在三种工矿下进行了的行驶仿真,通过行驶仿真,得到了链轮的转矩。4.对减速器进行动力学仿真。结合虚拟样机模型以及由RecurDyn软件仿真得出的转矩,对减速器进行了仿真分析,研究了减速器的各级速度和轮齿啮合力等。5.对减速器关键部件进行有限元分析。在有限元分析软件ANSYS软件中,施加由ADAMS中测出的受力情况,对减速器中的行星架进行了结构有限元分析和动力学分析,并校核了其各项性能。更多还原

【Abstract】 Using the technology of virtual prototyping, which is a bran-new product developing technology, we can modify the design expediently before the physical prototype is produced. Using the technology of Virtual Prototype becomes the developing direction of mechanical trade in the course of product design. Replace the physical prototype with virtual Prototype of a machine andinnovate design、test and assess the products, it can shorten development periodof products, reduce the cost of development products, improve the designing quality of the products, improve the ability facing the customer and marketdemand, also can accelerate the transformation of new technologies to new products.This thesis regards mine roadheader’s travelling reducer as the research object, using the three-dimensional design software UG、analytical software of Virtual Prototype ADAMS & RecurDyn and FEA software ANSYS, carries on entity’s modeling and simulation to the reducer. In this thesis, with virtual prototyping technology, the simulation analysis of mine reducer is implemented based on CAD/CAE software.1. The 3-D model of the roadheader’s travelling reducer is built. The gear and other components such as shaft(gear shaft)、bearings and gear box are built with the modeling module of the UG software. A virtual assembly and the interference analysis of the reducer are work out through the assembly module of UG.2. A virtual prototype model of reducer is constructed. The UG model will be transformed into ADAMS through the format of Parasolid. A virtual prototype model is built after system constraints, load and drive are added in ADAMS. The verification of prototype model is implemented through kinematic simulation in ADAMS.3. The running simulation of the simplified model of roadheader are done. Simplified model of roadheader is built based on the Korean dynamic simulation software RecurDyn. The running simulation under three different working conditions are done in this software, and through the running simulation the torque of the sprockets wheel are obtained.4. The dynamics simulation of reducer is done. The dynamic simulation of the virtual prototype of the reducer is done combining with the virtual prototype and the torque of the sprocket wheel in ADAMS. The angular velocity and meshing forces are studied.5. The finite element analysis for the key part of the reducer is done. The FEA static and dynamics analysis of the planetary carrier of reducer is made by the FEA software ANSYS based on the boundary conditions from ADAMS, and several characteristics are tested either.更多还原
