  1. 1. The Energy Efficiency Model of a DC Motor for the Control of HEVs

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : JIACHENG CAI; [2020]
    Keywords : Efficiency map; DC motor; test bench; polynomial regression; K-means; Effektivetetskarta; likströmsmotorn; testbänk; polynomuttryck; K-betyder;

    Abstract : This thesis studies a DC motor for a racing hybrid electric vehicle (HEV) prototype.The development of optimization-based energy management strategies (EMS) necessitates an accurate quasi-static model of the driving motor, which includes a 2D efficiency map with the torque outputand rotating speed as the inputs.

  3. 2. Spinodal Decomposition in the Binary Fe-Cr System

    University essay from KTH/Metallografi

    Author : Saeed Baghsheikhi; [2009]
    Keywords : Fe-Cr binary system; phase diagram; miscibility gap; spinodal decomposition; nucleation and growth; hardness; TEM; contrast modulations;

    Abstract : Spinodal decomposition is a phase separation mechanism within the miscibility gap. Its importance in case of Fe-Cr system, the basis of the whole stainless steel family, stems from a phenomenon known as the “475oC embrittlement” which results in a ruin of mechanical properties of ferritic, martensitic and duplex stainless steels.
