【摘要】 环板式针摆行星传动是国际上创新研究出的一种具有实用价值的新型传动，它是在分析比较以渐开线为齿形的诸种环板式减速器和常规摆线针轮行星传动各自优缺点的基础上创新研制的一种新型摆线针轮行星传动。而双曲柄四环板式针摆行星传动是环板式针摆行星传动的一种，具有体积小、重量轻、传动比范围大、传动效率高、传动平稳、结构简单、承载能力大等诸多优点。由于环板式针摆行星减速器尚处于研究阶段，其设计与制造缺乏可靠的理论依据，对其进行动力学研究，剖析振动机理，提出相应的改进措施，设计具有优良动态性能的行星齿轮装置，对机械工业发展具有重要的意义。本文在已有研究的理论基础上，围绕双电机驱动四环板式针摆行星传动系统的动态特性分析这一专题，开展了相关研究。运用三维建模软件Pro／E，建立了各个构件的三维实体模型，运用现代计算机大型有限元分析软件ANSYS，分别求解出每个构件的固有频率和振型，并且求解了部分装配体的固有频率和振型，将计算结果与试验结果对照，找出对振动影响较大的构件或组件，并提出相应的改进措施，为进一步分析双曲柄四环板式针摆行星传动的动力学行为，改善其动态特性建立坚实的理论分析基础。刚度激励是齿轮啮合的主要激励形式之一，因此齿轮啮合刚度计算的准确与否关系着整个齿轮传动系统研究结果的准确性。根据新的修形齿廓有隙啮合分析方法，计算出摆线针轮在啮合过程中的受力和变形，用理论的方法计算了摆线针轮的啮合刚度。运用ANSYS／LS-DYNA模块，该模块可以模拟现实世界各种复杂的碰撞问题，对摆线针轮的运动进行了动态仿真，运用仿真结果求解摆线针轮的啮合刚度，并与理论计算结果进行对比，两者相互验证。并对求解的啮合刚度进行分析，提出对样机的改进方案。更多还原

【Abstract】 Double crank four ring-plate-type cycloid drive is a new-type drive. After analyzing the merits and the shortcomings of involute gear ring-plate drive and traditional cycloid drive each, we proposed the double crank four ring-plate-type cycloid drive, which possess the merits of small volume, light weight, wide range of transmission ratio, high efficiency, uniform operating, well knit-structure, high load-capacity. Because double crank four ring-plate-type cycloid drive is still at the stage of studying, its design and manufacture lack the reliable theoretical foundation, it is extremely meaningful for mechanical industry to study its dynamics, to analyze the vibration mechanism, to present the measures to improve performance, and to design planetary gear trains with super performance.This dissertation mainly explores the dynamics of the double crank four ring-plate-type cycloid drive.The 3D solid model of the every parts of Ring-plate-type Pin-cycloid gear reducer is carried out in the Pro/E system. Based on this solid model, the dynamic model of all parts is established in finite element analysis system-ANSYS and studied the inherent characteristics of every parts. Compare the analysis results with the test, it can be found that the parts to largely impact the inherent characteristics. It is the foundation of the dynamic analysis of the whole reducer system.The rigid drive is one of the main drive forms of the gear meshing. So the accurate of result of the gear meshing rigidity is related to the accuracy of the dynamic analysis of the whole reducer system. It has been calculated that the stress and distortion of the pin-cycloid gear according to the analysis method of new tooth profile. And the meshing rigidity of the pin-cycloid has been calculated with the theory method.Using ANSYS/LS-DYNA module, this module can simulate some complex collision in the real world. It carries on the dynamic simulation of the cycloid gear and can receive the gear meshing rigidity. It can contrast with the result in theory method. And carries on the analysis to the meshing rigidity, proposes the improvement program of proto type.更多还原
