Mechanical Engineering is a field of engineering that focuses on the design, creation, analysis and maintenance of mechanical systems. This field of engineering applies physical principles to the design and manufacturing of various machines and components for use in industry, and the service and maintenance of existing machinery. From car engines, medical equipment and construction machinery to sophisticated aerospace components, Mechanical Engineers work with almost every aspect of today’s industrial world.

At Freelancer.com clients can hire a Mechanical Engineer to develop some of the most advanced engineering solutions. Unique applications of principles of mathematics, materials science and physics are used to examine how varying forces like gravity and friction affect different designs. Mechanical Engineers also work with computers to help them create precise drawings and simulations related to the product they’re creating or repairing.

Here's some projects that our expert Mechanical Engineer made real:

  • Develop energy efficient systems such as chillers and other climate control systems
  • Creating detailed mechanical parts from 3D models
  • Designing robust structures for static loads
  • Generating CAD files for precise machining
  • Creating precise schematics for different construction projects
  • Analyizing energy consumption involved in engineering operations
  • Producing flat pack designs for cutting out parts
  • Design consultation for various fabrication projects
  • Contucting naval architectural reviews

Projects related to Mechanical Engineering can range from complex construction or design-related tasks to more intricate analyses or simulations. With this flexibility, it's no wonder that clients continue to leverage the skill sets of Mechanical Engineers through Freelancer.com. With access to some of the most talented workers in this field clients can expect projects completed quickly, efficiently and within their budgets.

    I have a working Fusion 360 model of a patented oscillating tool attachment. The existing Fusion 360 assembly was intentionally created to clearly communicate structure, function, and motion — primarily for patent and legal review. That objective has been met. The file needs a professional mechanical redesign and full DFM (Design for Manufacturability) refinement for prototype production. The assembly includes both polymer (injection-molded) and metal (CNC or stamped) components with a unique mounting interface. Proper wall thickness, draft angles, tolerances, and realistic fits are critical. You will receive my current Fusion files. Your task is to rebuild or refine the model so that: • All components are cleanly structured and clearly named • The design is fully paramet...

    I need a hands-on field service engineer who holds an EPA 608 refrigeration certification and can spend most of the time keeping our food-processing equipment running at peak efficiency. The heart of the job is maintenance—specifically, accurate calibration and adjustment of temperature controls, pressure switches, flow meters, vacuum and any other critical components that keep product quality and safety within spec. You will also travel to customer sites to install new food-processing machinery. Once the hardware is in place you may have to work with PLCs, tweak ladder logic, and verify that every sensor and actuator reports correctly before sign-off. Although troubleshooting is part of life in the field, I measure success by how well the preventive work you do avoids unplanned dow...

    Project Description: CFD–FSI Analysis of Flexible Flapping Wing Aerodynamics This project focuses on the numerical investigation of unsteady aerodynamics of a flapping wing with flexible deformation using coupled Fluid–Structure Interaction (FSI) simulations. The objective is to understand how wing flexibility and deformation affect vortex formation, wake evolution, pressure distribution, and aerodynamic force generation (lift and thrust). The study will be carried out using transient CFD coupled with structural deformation, where the wing undergoes prescribed flapping motion and deforms under aerodynamic loads. The interaction between fluid flow and structural response will be analyzed over multiple flapping cycles. Key Scope of Work Perform transient CFD simulations of a ...

    I want to take traditional conveyor-belt tensioning a decisive step forward by creating a completely motorized, cable-and-pulley system that adjusts itself on the fly. The goal is to maintain optimal belt tension at all times—compensating automatically for stretch, wear and changing load—so downtime, manual checks and premature belt failures disappear. My vision centres on a robust mechanical layout married to intelligent control. Integrated real-time tension monitoring, wear-detection sensors and load-variation sensing will feed a compact controller that drives the motorised actuator. Wireless control and monitoring must let operators check status or initiate overrides from a tablet if needed, and the firmware should generate predictive-maintenance alerts long before an issue...

It will be built around an NVIDIA Jetson Orin Nano and includes: 10.1" QLED touchscreen (Waveshare 10.1HP-CAPQLED) 2x Logitech Brio 4K cameras (forehead + chin) ReSpeaker Mic Array v3 2x Visaton speakers (in ears) Class-D amplifier UPS power module 3x 21700 lithium batteries (in base for stability) 40mm exhaust fan Custom 3D printed bust-style enclosure I have already created a complete build guide with exact component dimensions and assembly plan (attached).

    I have a gas-liquid separator whose internal geometry needs to be verified before fabrication. The task is a complete CFD study of multiphase flow through the vessel, capturing the interaction between gas and liquid phases. My main concerns are flow distribution across the internals, overall pressure drop, and the resulting phase-separation efficiency, so the model must resolve these three metrics quantitatively. A CAD file of the current layout, design operating conditions, and fluid properties will be supplied at project start. The simulation should be run at the specified throughput, using an appropriate multiphase model (VOF, Euler-Euler, or similar) in Fluent, CFX, OpenFOAM, or another recognised solver, with mesh independence demonstrated. Please include transient behaviour if it ma...

    I need a technical engineering document currently written in English rendered into clear, precise Spanish without losing any of the specialised terminology or formatting. The file contains formulas, figures and a few embedded tables, so consistency in unit notation and layout is important to me. You will work directly from the source file and return a Spanish version that mirrors the original structure, plus any notes where terminology may be ambiguous. If you like to rely on CAT tools such as Trados, MemoQ or Wordfast, feel free—I welcome anything that helps maintain term consistency and speeds up delivery. Engineering background or proven experience with manuals, datasheets or specifications is a must, as the text includes references to mechanical tolerances and material standar...

    I’m developing a humanoid dummy that relies on a multi-degree-of-freedom, articulated system and I need a mechanical engineer or product designer who is comfortable turning intricate motion concepts into manufacturable reality. it will be 3d printed and to be used for fashion apparels. it must be capable of performing complex yoga poses You will receive my early sketches, target ranges of motion, load cases, and envelope constraints. From there I’d like you to: • Build the full 3D CAD model, refining joint architecture, clearances, and fastener strategy. • Run a basic kinematic check to verify smooth, collision-free travel across the full range. • Deliver production-ready drawings (GD&T, exploded views, BOM) alongside STEP and native files. • Hig...

    I need a detailed BIM model focused exclusively on the plumbing scope of our project so the design team can review, coordinate, and visualize every pipe run before construction starts. The model should follow current MEP standards and be built in Autodesk Revit (or another widely compatible platform you prefer, as long as I receive shareable RVT and IFC files). All fixtures, pipe sizes, slopes, valves, and equipment must be shown in 3-D, correctly hosted to the architectural backgrounds I will supply. Because this model will serve design-visualization purposes rather than fabrication, I am looking for realistic geometry and clean object naming—not spool sheets. Clash detection against the existing architectural shell is still important, so please run a Navisworks coordination test a...
