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

单片陶瓷结构部件在技术上的合理应用在于金属材料无法解决的领域。特别是在陶瓷材料的特殊特性优于金属材料的情况下，如耐磨损、耐高温和耐腐蚀。在提交的项目中，应开发和分析系统设计解决方案，使单片陶瓷部件能够在摩擦学，机械和热应力的组合下集成在机械应用中。为此，应分析陶瓷部件结构设计的最新技术，并以斯特林电机中出现的气缸-活塞组合为例，制定有条理的设计过程。应开发一个4缸斯特林电机的实验平台，并进行不同的示范陶瓷解决方案的测试。应在可用的摩擦学试验台上进行初步试验，以支持陶瓷材料的选择，该试验台必须进行修改。在项目的第二阶段，应对提出的设计方案进行实验验证，并推导出一般设计规则。

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.
