2 ) the inductance transducer used to identify large wear particle is developed . the analytical theory of wear particle and detection windings are expatiated and inner magnetic distribution of inductance transducer is discussed, the geometry parameters are optimized by using genetic algorithm, and the finite element analysis method is used in the designing 2)研制了識別大磨損顆粒的材質和測定其粒度的電感傳感器,闡述了磨損顆粒與檢測線圈的解析關系,探討了傳感器的理論基礎,分析了電感式檢測傳感器內部的磁場分布,并應用遺傳算法優(yōu)化了傳感器幾何參數,最后進行了有限元仿真分析。
Finally an integral software module for cam mechanism contact pressure analysis is developed in ansys . this work has formed an integrated technical route from geometrical design to tribological design . it may contribute to the theories of wear design and arithmetic, and can be used for reference to the cam-follower tribological design 本文的工作形成了從凸輪幾何設計到摩擦學設計的一條完整的技術路線,已經可以基本作為內燃機凸輪機構摩擦學設計軟件系統的雛形,今后可以在此基礎上開發(fā)凸輪機構設計的專家系統軟件;本文還在完善工程磨損設計理論和計算方法方面有所貢獻,可以為凸輪機構的實用摩擦學設計提供參考和借鑒。
