Integral lightweight design of gears via laser beam melting

通过激光束熔化进行齿轮整体轻量化设计

基本信息

项目摘要

In increasing resource efficiency of gear drives lightweight design is essential in order to reduce the masses that have to be accelerated as well as the torque of inertia and therefore minimize irreversible energy losses. At the same time, unbalances may be decreased leading to an increased gear life. This also holds a secondary lightweight potential in designing surrounding gear components according to a reduced load induced by the primary component. Lightweight concepts have to be a trade-off between material strength, efficiency as well as NVH (Noise, Vibration, and Harshness). Hence, a consideration on a system, component as well as material and manufacturing level is crucial.The framework of this project focusses on the possibilities of lightweight design by means of a combination of construction, material and manufacturing relying on additive manufacturing via LBM (Laser Beam Melting). LBM offers the integrated manufacturing of highly complex and integrated structures due to a layer wise buildup of the part. At the same time, high strength materials may be used. The flexibility of LBM is employed to implement lightweight structures into less stressed part segments. These structures comprise classical topologies like load-adapted struts or lattice structures, which have to be evaluated based on simulations and experiments with regard to their static and fatigue strength. As a sub research objective, lattice structures for the implementation of a conformal gas cooling are evaluated. This way porous part segments are created that can be used as an evaporation cooling zone for special thermal conditions. In summary, the overall research objective is a comprehensive design guideline specifically for LBM for integrated lightweight gear wheels.
为了提高齿轮传动的资源效率,为了减少必须加速的质量以及惯性力矩,从而最大限度地减少不可逆的能量损失,轻量化设计是必不可少的。同时,可以减少不平衡,从而延长齿轮寿命。这也在根据主要部件引起的减少载荷来设计周围齿轮部件时具有次要的轻量化潜力。轻量化的概念必须在材料强度、效率以及NVH(噪音、振动和粗糙度)之间进行权衡。因此,对系统、组件以及材料和制造水平的考虑是至关重要的。该项目的框架专注于通过激光熔化(LBM)实现结构、材料和制造相结合的轻量化设计的可能性。由于零件的分层堆积,LBM提供高度复杂和集成的结构的集成制造。同时,可以使用高强度材料。LBM的灵活性被用来将轻量化结构实现为应力较小的部分。这些结构包括经典的拓扑结构,如负载自适应的支柱或格子结构,这些结构必须基于模拟和关于其静态和疲劳强度的实验进行评估。作为一个次研究目标,评价了用于实现保形气体冷却的晶格结构。这样就产生了多孔部件段,可用作特殊热条件下的蒸发冷却区。总而言之,总体研究目标是一个专门针对集成轻型齿轮的LBM的全面设计指南。
