Design of monolithic ceramic components in the mixed friction area under combined tribological, mechanical and thermal stress

由整体陶瓷制成的结构部件在技术上合理的应用在于金属材料失效的领域。这些应用尤其适合陶瓷材料的特性优于金属材料的应用，如耐磨性、耐高温性和耐腐蚀性。在提交的项目中，应开发和分析系统的设计解决方案，使单片陶瓷部件在摩擦，机械和热应力组合下的机械应用中得以集成。为此，应分析陶瓷部件结构设计的最新技术水平，并以气缸-活塞组合为例，例如斯特林发动机中出现的气缸-活塞组合，应开发出一个系统的设计过程。应开发4缸斯特林电机的实验装置，并对不同的示例性陶瓷解决方案进行测试。应在现有的摩擦学试验台上进行初步试验，以支持陶瓷材料的选择。在项目的第二阶段，应通过实验验证拟议的设计解决方案，并得出一般设计规则。

A technically reasonable application of structural components made of monolithic ceramics lies in the area where metallic materials fail. These are especially applications where the specific characteristics of ceramic materials excel the metallic ones, like durability against wear, high temperatures and corrosion. In the submitted project systematic design solutions shall be developed and analyzed, which enable the integration of monolithic ceramic components in mechanical applications under combined tribological, mechanical and thermal stress. For that matter the state of the art in the structural design of ceramic components shall be analyzed and using the example of a cylinder-piston-combination, for example appearing in a stirling motor, a methodical design process shall be developed. An experimental rig of a 4 cylinder stirling motor shall be developed and the testing of different exemplary designed-for-ceramic solutions shall be conducted. Preliminary tests to underpin the choice of ceramic materials on an available tribology test rig, which has to be modified, shall be carried out. In the second phase of the project the proposed design solutions shall be validated experimentally and general design rules shall be derived.
