• Handled the brakes and suspension team of Hyperloop @USC for the Hyperloop Pod Competition

• Formulated a bolt joint design guideline to calculate the factor of safety of bolted joint connections PROFESSIONAL EXPERIENCE

Wheels India Ltd, Suspension Design Engineer, Chennai, India Jun 2011 - Dec 2014 Pusher Lift Axle Project:

• Led the development of pusher lift axle air suspension system for 31 ton vehicle

• Conceptualized the design of air suspension system based on vehicle package space

• Utilized Solidworks software to prepare mechanical designs of air suspension components

• Performed FEA on suspension brackets and leaf springs to analyze stress distribution, using COSMOS and ANSYS

• Prepared DFMEA and DVP to assess the failure mode and to state the test cases and performance targets respectively

• Generated 2-D drawings utilizing basic GD&T characteristics for suspension components in AutoCAD

• Created bill of materials, work and service instructions to instruct and guide the service team at customer end

• Presided over Cross Functional Team meetings (CFT) to expedite the product development by resolving production issues

• Arranged customer meeting to present FEA, testing, quality reports and to review progress on product development VAVE Project:

• Executed an Anti roll bar eye bracket weight reduction project which led to a weight savings of 3Kg on the bracket per vehicle USC ACADEMIC EXPERIENCE

Hyperloop @USC (Student Organization) - Design Engineer Aug 2015 - Dec 2016 Brake System:

• Modeled the disc brake system with redundancy for the Hyperloop pod to stop it with 1G Deceleration

• Calculated the braking force, braking torque, clamp load and brake pressure required to apply the brakes

• Performed a basic thermal analysis to analyze the temperature distribution on the disc for one second after applying the brakes

• Engineered the pneumatic schema for the air brake distribution system Suspension System:

• Designed the trailing arm suspension system for the Hyperloop pod to support 3G vertical load and 1G braking Load

• Derived the ride system characteristics such as stiffness, frequency and damping force of the suspension system

• Performed dynamic analysis in ADAMS VIEW to evaluate the stiffness and damping characteristics of the suspension Upright System:

• Established design requirements to design and develop the upright system which would connect the electric motor and wheels in a direct drive configuration with radial bearing arrangement for Hyperloop pod

• Utilized SKF bearing design guideline to select bearing size, which would support axle shaft and housings

• Simulated the upright system to find the stress points on axle shafts and housings using ANSYS Academic Project Aug 2015 - Dec 2015

• Developed a numerical tool using Matlab to assess the failure criterion of a composite laminate when subjected to in-plane loads
