Prasad H R

Currently supporting Kubota construction equipment machinery in the USA.

• Aiding in the design and development project for CTL/SSL's new vehicle.
• Supporting the design of mechanical systems for compact truck loader assemblies, encompassing undercarriage components, boom bucket linkage systems, mounting brackets, and hydraulic pipe layouts.
• Collaborated with the simulation team to support FEA-driven design decisions for loader vehicle development.
• Developed 2D manufacturing drawings, along with BOMs.

Prior project: Hood lift mechanism design for CNH Tractor.

• Hood frame weight: 220 kg; handle force requirement: 200 N (20 kg); optimal lifting handle height from locking position: 1 meter.
• Analyzed kinematics and forces in linkages, focusing on 4-bar mechanisms to fulfill functional and safety criteria.
• Evaluated force calculation (handle force vs. height) to meet customer requirements and spring design criteria for a 4-bar linkage mechanism.
• Developed a concept model for assembly and conducted a review with the customer.
• Engaged in final concept selection with the customer according to criteria such as cost, operator input, effort, force variation from temperature, development risk, serviceability, etc.
• Developed assembly and component-level models for FEA analysis.
• Serving as the Technical Lead in Creative Synergies Group, Bangalore, from May 2023.
• Division: Heavy Engineering - Off-Highway and Transport.

Project: Upstream Downhole Oil and Gas Completion Tools - Halliburton.

• Technical assistance for engineering activities through RTA (Request for Technical Assistance).
• Provided support to the client for design and technical documentation using product data management activities.
• Utilize GD&T on engineering drawings to ensure form, fit, and function of the tool.
• Preparing mark-ups to integrate required design changes, and assigning tasks to drafting.
• Modification of existing tool design to enhance market sustainability (ECR/ECN).
• Execute calculations such as tensile burst, collapse torque, bearing strength, etc.
• Develop and evaluate designs, check layouts for validating tool design specifications, and analyze the functionality of the tool for sand control, flow control, and permanent packers components.

Projects: Heavy Transportation Vehicle (Goldhofer, Germany), Truck Body Industries (Wabash National, USA), Hydraulic Cylinder.

Project: Construction of mainframe design for a 6-axle bogie and low-profile telescopic deck.

• Creation of GA drawings (proposal drawings) with different trailer combinations for the sales department, 6-axle bogie modeled with a top-down approach (skeleton modeling).
• Conversion of a 5-axle modular trailer with a wheelbase of 1500 mm to an 8-axle, 6-axle, or 4-axle modular trailer with a 1650 mm wheelbase.
• Formulated a checklist based on customer guidance, and constructed a manufacturing model and drawings.

Project: Conversion of Mechanical Ramp from 50T to Hydraulic-Actuated Ramp 80T.

• Primarily focused on two concepts related to construction, utilizing an existing 50t mechanical ramp to create an 80t hydraulic ramp.
• Designed a hydraulic ramp featuring cross tubes, following a top-down approach, and performed FEA analysis for load-bearing capacity and deflection with Creo Simulate.
• Revalidates F.E.A. input remodeled with sheet metal instead of cross tubes.
• Released drawings for production with customer approval.

Project: Design optimization of a 16-foot reefer truck body, executed at the client location in the U.S.A.

• Aid for the client in revising the existing 16-foot reefer truck body assembly and components related to material adjustments (transformed material for main bodies from steel/aluminum to composite structures).
• Design/Technical Documentation using Product Data Management activities.
• Developed vehicle body models and manufacturing drawings according to the updated vehicle structure.

• Customized hydraulic winch design for cranes, defense, and material handling industries.
• Project Example: Design of 6T Hydraulic Compact.
• Creation of GA drawings and a technical specification document based on customer requirements.
• Winch specifications required: capacity of winch 6 tons, operating pressure 180 bar, flow 11 LPM.
• Performed design calculations to get the required torque and load on the winch drum.
• Modified the existing gearbox to achieve a minimum torque of 900 kg-m, and reduced the size.
• Standard motor of 800 cc/rev (manufactured in another unit), brake, and distributor valve used.
• Created assembly and component drawings for production, and performed a quality test (load testing, flow testing, speed testing, leaking testing) on our shop floor prior to winch dispatch to the customer.

• Trained in the Production and Planning Department, Heat Treatment and Casting, Calibration (Quality Department).
