论文题目汽车变速器的三维造型与运动学仿真
摘要:汽车变速器是整个汽车传动系统中相对关键的一个部件,变速器对整车的动力性与经济性、操纵的可靠性与轻便性、传动的平稳性与效率都有着较为直接的影响。以Pro/Engineer ,建立变速器各零部件的三维实体造型,根据它们之间的约束关系进行整体装配建模,检测变速器整体模型中个零件之间的干涉情况,以确保运动仿真的顺利进行;在Pro/Mechanism模块中建立变速器的运动仿真模型,动态模拟变速器的整个工作过程。该方法实现了变速器设计阶段的可视化,使原来在二维图纸上难以表达和设计的运动变得非常直观和易于修改,从而提高了汽车变速器的设计质量和效率。

ABSTRACT: Auto transmission is the whole car transmission system, one of the crucial parts relative performance of vehicle transmission with economy, manipulating the reliability and portability, transmission and steadiness and efficiency have relatively direct influence. To Pro/e for tools, set up the transmission of parts of three-dimensional molding, according to the constraint relation between them on the whole assembly modeling, detection transmission in a whole model between the parts, to ensure the interference of the motion simulation smoothly; In Pro/Mechanism in the module of establishing transmission, dynamic simulation motion simulation model of the whole process of the transmission. This method is realized the visual transmission design phase in the original 2d drawings to express and design sports e very intuitive and easy to modify, thereby improving the auto transmission design quality and efficiency.
Keywords: transmission, entity modelling, assembly modeling, movement simulatio
