Research

  • Topology optimization for crashworthy designs

    Graduate Research  August 2007 - Current

    Develop the concept designs for structures under going crash events. A novel methodology called Hybrid Cellular Automaton (HCA) is used to optimally distribute the given material within the design domain to obtain the desired performance characteristics. The methodology uses the concept of fully stressed design to obtain energy absorbing structures.

    Crashworthy structures with controlled energy absorption

    Graduate Research  January 2008 - Current

    Develop an HCA based topology optimization technique to design energy absorbing structures where energy can be transferred desirably within the structure. This method uses compliant mechanism synthesis approach along with fully stressed design synthesis to obtain desired energy flow paths within the design domain.

Reliability based designs for crashworthiness

Graduate Research  January 2009 - Current

Develop a framework to incorporate the notion of reliability into crashworthy designs of automotive vehicle components. A semi coupled reliability based design methodology is proposed in which independent reliability assessments are done on the designs at various intermediate levels during an iterative design cycle of a crashworthy structure.

     

Projects

  • High-speed rail pantograph control system design

    January 2009 - May 2009

    A simplified mechanical model for active pantograph control system is studied for stability and transient performance characteristics. Optimal control gain is found which minimizes the steady state error. State feedback design is used to obtain the feedback gains which stabilizes the system response.

    Failure analysis of nutcracker (Failure of Materials)

    August 2008 - December 2008

    A typical failed nutcracker was studied for the reasons behind its failure using the various failure mechanics theories and observations. The project involved the study of the specimen under SEM (scanning electron microscope) to find the possible crack initiation and propagation mechanism. Subsequent mathematical analysis confirming the proposed mechanism and failure prevention strategies are studied.
