Abstract
The aim of this paper is to analyze Train Driver Cabin AC kit to improve performance of Rail AC unit. First CFD analysis has been carried out on the existing design to find the airflow on the condenser side. Based on the analysis result, design modification has been done to improve the air flow on the condenser side and thereby improving the cooling capacity of the unit. CAE analysis has been carried out to strengthen mount brackets of condenser fan. With the design changes, there is significant improvement found on the structural integrity. Modal frequency improved and dynamic stress been reduced. Based on final modified design, proto was developed, tested and found OK which further verified with CAE/CFD results.CAE analysis has been carried out using ABAQUS/Hypermesh software and CFD using STAR CCM+.
