Hire the Best Automotive Engineers
in India

👋 Hi there! I'm Junaid Alam, I help Startups, EV companies, Robotics teams and New product development mechanical systems from concept design to validated performance using a structured design → simulation → validation approach—reducing physical prototyping, development time, and engineering risk. I am a Mechanical Systems and Vehicle Dynamics Engineer with over 5 years of hands-on experience in automotive and mobility-focused industry, working across passenger vehicles, off-road vehicles (ATV/UTV), powertrain and transmission, robots, and planetary rovers. My strength lies in combining robust CAD design with high-fidelity multibody dynamics simulations and validation through CAE , and correlating results with real-world behavior. Rather than treating CAD and CAE as isolated tasks, I design components and mechanisms with simulation intent from day one, ensuring designs are structurally sound, dynamically stable, and manufacturable before hardware is built. Core Services : 1. Mechanical System Design (CAD) Parametric 3D CAD design and assemblies using CATIA and SolidWorks, with material selection and thickness optimization driven by structural and dynamic load requirements. 2. Multibody Dynamics (MBD) & Mechanism Simulation High-fidelity rigid and flexible body simulations using MSC ADAMS and Altair MotionView to validate kinematics, compliance, contact behavior, and mechanism performance. 3. Vehicle Dynamics, Ride & Handling Suspension kinematics and compliance (K&C) analysis, ride and handling evaluation, and vehicle behavior modeling using MATLAB/Simulink for on-road and off-road applications for both Bikes and Cars. 4. Powertrain & Driveline Analysis Torque flow, efficiency, torsional eigenfrequency, and gear rattle analysis, with 1D system-level simulations in Amesim to assess driveline and shift behavior. 5. CAE & Structural Validation Meshing and structural analysis using Altair HyperMesh and ANSYS, including load case identification (RLDA) and durability-focused validation. 6. Engineering Training and Technical Guidance: I Provide structured training on multibody simulations (ADAMS / MotionView) and vehicle ride and handling evaluation, tailored for engineers and teams. 💡 Projects That Make Me Stand Out: Suspension Kinematics & Compliance (K&C) Analysis: Conducted suspension kinematic and compliance analysis using MSC ADAMS, evaluating ride and handling performance, wheel travel characteristics, and compliance effects to support suspension tuning decisions. Transmission System Co-Simulation (MBD + 1D Controls): Integrated a multibody dynamics model of a transmission system with a 1-D vehicle and control model in MATLAB/Simulink to validate torque flow, shift strategies, and transient system behavior under real driving scenarios. DCT Park Lock Mechanism (MBD): Developed and validated a multibody model of a park lock mechanism in Altair MotionView, identifying peak contact loads and ensuring reliable engagement across operating conditions. Planetary Rover Dynamics: Performed multibody dynamics analysis of a rover system using MSC ADAMS to study mobility, articulation behavior, and load transfer over uneven terrain. Off-road Vehicle Ride & Handling: Led suspension modeling and ride/handling optimization for ATVs and UTVs, supported by physical testing such as bump rig, brake, and stability tests. 🔧 Tool Expertise: MSC ADAMS (Car/View) Altair Motion View/Motion Solver MATLAB/Simulink Hypermesh / Hyperworks Amesim , CarSim and BikeSim CATIA V5 & Solidworks Ansys & Abaqus 🎯 Why Work With Me? I bring not just simulation proficiency, but a problem-solving mindset and an engineer's intuition. I provide : End-to-end ownership: design → simulate → validate Strong intuition backed by simulation and real-world testing exposure Clear technical communication and structured problem-solving Reliable delivery with attention to engineering detail Whether you’re developing an EV subsystem, robotic mechanism, off-road vehicle, or a new mechanical concept, I can help you validate performance early and move forward with confidence. 🌍 Let’s Connect! I'm open for both short-term consulting and long-term collaborations. If you’re looking for a mechanical engineer who can design intelligently, simulate accurately, and validate realistically, send me your problem statement and timeline—I’ll take it from there.
