下载后可任意编辑 摘 要 YOTCHP8756液压油泵是大连液压机械厂的主要产品之一。它的工作效率和容积效率都比较高，可以广泛应用于很多场合。但该厂产品开发手段基本是传统的串行方法，设计试制出原型样机，然后测试、验证并分析它们，但是由于工程师设计出产品，往往要经过多次反复的试制才能成功进入市场，产品开发时间长；在对设计大型、复杂程度较高的产品时，由于设计手段及生理因素的限制，设计易出错和人为疏漏，并缺乏对产品的制造、装配工艺性的预见，影响设计质量；产品设计、制造费用高，产品成本上升，缺乏市场竞争力。 通过使用虚拟装配技术能够更加真实生动的反应液压油泵的装配过程，为了能够了解在实际载荷下关键部位的变形和应力的情况还需要使用到有限元分析技术。 本次毕业设计是在3ds max软件环境下对液压油泵进行虚拟装配动画制作，通过三维动画生动的描述液压油泵的装配过程。同时在HyperMesh软件下环境下进行单元网格划分和有限元分析，通过分析的结果真实反映出液压油泵的轴受力及载荷的状况。 关键词：液压油泵 虚拟装配 液压泵轴 有限元分析 Abstract The YOTCHP8756 hydraulic pressure pump is the main products of the Dalian hydraulic pressure machine factory. Its work efficiency and the capacity efficiencies are all high, and can be used in lots of situations. But the factory s products development is basic on a traditional . first, they design manufactures as a prototype machine on a trial basis, then make the test、verify and analyze. Because engineers design the produces usually base on many times manufacture trial, only after the manufacture trial, the produces can succeed put into the market, it means the time of product developing is too long; Because of the design restrict and the physiology factor, then when they design the more large and complicated product, design would make mistakes and artificial careless easily, and lack the foresee of the product manufacture and assemble craft ,this can be a influence to design quantity; It also make more designing、manufacturing expense of the product, the product s cost would be rising, then the produces lack the competition ability. Through the use of more realistic virtual assembly vivid response to hydraulic pump assembly process, in order to understand the key parts in the actual load of the deation and stress of the situation also need to use finite element analysis techniques. The graduation project is the environment in 3ds max software, virtual assembly of hydraulic pump animation, animated by a vivid description of three-dimensional hydraulic pump assembly. While under the HyperMesh software environment for cell mesh and finite element analysis, reflected through the true results of Hydraulic pump shaft by the force and load conditions.
