1. Drafting Services
Moving from 2D to a 3D CAD system improves how your ideas and concepts are communicated, both inside and outside your company. It’s simply easier to understand a design presented in 3D, as opposed to a static 2D drawing.
We provide accurate 2D-to-3D, and 3D-to-2D conversion of designs, according to the customers’ requirements. We can incorporate geometric dimensioning and tolerancing (GD&T), component level materials, assembly level bills of materials, engineering configurations, design intent, etc. We also provide weldments and sheet metal solutions.
If you have an actual product, hand-sketched design, or existing 2D drawing of your component/part, that you need converted into a 3D model, please feel free to contact us.
2. Customised Library components
SolidWorks provides default library components that are frequently used by our customers. If you have more components that are frequently used in your assembly as well, then why not create your own customized library?
Our SOLIDWORKS Elite Application Engineer works closely with our customers to understand their work process and create components for their customized library, which reduces the working time. We have created libraries for various customers in the field of hydraulic and pneumatic components, ribs, and gussets.
3. Creating scaled 3d models
Without 3D CAD files, we are left only with images and sketches, which are often insufficient to help us visualize a component. Using proportionality, our professional SolidWorks engineers are able to recreate 3D models that are to scale, using image references alone.
4. 3D CAD animation
3D CAD animation enables you to explain the design mechanism and assembly, as well as how it fits with related products. Videos are extremely powerful for communications between technical and non-technical people. We can provide various animations solutions, including:
- Timeline-based animation creation
- Exploded view animation, to help explain assembly/disassembly
- Video output, frame rate, and other controls
- Save video for viewing by others
Realistic renders of a 3D model can often help your prospective client better engage with your design. We offer assistance in creating high quality photo-realistic content that clearly and emotionally depict the products in the real world.
FEA Simulation Services:
Our Engineers are Certified CAD and CAE Simulation experts, experienced in providing consultation services to different industry sectors. We have produced solutions for a wide variety of Engineering problems, including Structural, Thermal and Fluid Flow, and Design Optimization etc.
Our areas of expertise include (but are not limited to):
1. Linear static Stress analysis
Linear Static analysis helps to determine structural behaviour, and understand whether the design is subjected to yielding or permanent deformation during the loading conditions. It will provide information on Von mises Stress, Principal stress, Shear and Bending stress, Deformation, Strain and Factor of Safety, etc.
Linear stress analysis calculates the stresses and deformations of geometry given three basic assumptions:
- The part or assembly under load deforms with small rotations and displacements
- The product loading is static (ignores inertia) and constant over time
- The material has a constant stress strain relationship (Hooke’s law)
2. Frequency Analysis
Every design has its preferred frequencies of vibration, called resonant frequencies, and each such frequency is characterized by a specific shape (or mode) of vibration.
If a design’s natural modes and its expected service vibration environment are closely matched, a harmonic resonance may occur and lead to excessive loads, resulting in failure.
Using frequency analysis, Natural Frequencies and the mode shapes can be calculated. These can be used to implement preventive measures, such as changing materials, geometry or design sections and adding dampers. This will improve design performance and life in such vibrating conditions.
3. Thermal analysis
Heat Transfer between solid structures will affect design integrity and performance. Using Thermal structural analysis, mechanisms of heat transfer, such as heat conduction, convection, and radiation can be studied. Steady State and Transient (Time-Dependent) studies can be performed, and plots like Temperature Distribution and Heat Flux between solid structures can be created. These can be used to ensure values are within the design limits.
4. Design optimization
Structural Design optimization involves making parametric alterations to the design structure, relative to the design constraints. Without having to compromise the design quality, structural optimization can be used to create the lighter designs that meet all design requirements. With the structural optimization results, we can avoid over-engineering, manufacturing and prototyping costs, and reduce the design cycle time.
5. Nonlinear Static analysis
6. Linear/Nonlinear Dynamic analysis
Nonlinear stress analysis helps to determine the stresses and deformations of your design under most general loading and material conditions for:
- Dynamic (time dependent) loads
- Large component deformations
- Nonlinear materials, such as rubber or metals, beyond their yield point
Nonlinear studies are employed when the linear analysis assumptions are violated. These studies are more complex but provide highly accurate results. If the assumptions are preserved then the results of linear and nonlinear study will remain the same. The following are studies which can be done by Nonlinear Dynamics:
- Response Spectrum
- Random Vibration
- Nodal Time history
CFD (Computational Fluid Dynamics) is used to visualize how a fluid or gas flows, and the effects of the fluid’s interaction with objects that it flows past. Our certified CFD experts use leading CFD tools to provide accurate solutions to our customers, who are from semiconductor, aerospace and automobile industries.
We are able to assist with the following:
1. Internal Studies:
Internal studies are carried out when the fluid flow is bound by outer solid surfaces, e.g. movement of fluid inside a pipe or tanks. For internal studies, the fluid flows into the model and exits the model though outlets. A variety of results, such as fluid flow rate, pressure, velocity and temperature, can be determined at the outlet.
2. External Studies:
External flow analysis carried out when a solid medium is fully surrounded by the flow eg. flow over automobiles, aircraft etc. The fluid flow is bound by computational domain boundaries, instead of solid surfaces. We can predict various results, such as heat transfer from the fluid to the solid medium, can be studied.
3. Heat Transfer/Heat Sink Analysis:
Heat dissipation is a key parameter in any electronic design. We carry out heat transfer of conduction, convection, and radiation through solid and fluid bodies in your design, helping you understand heat transfer rates between the components. We can also perform optimization studies on your design to select an optimal heat sink.
4. HVAC Studies:
We can analyse and optimize HVAC (Heating, Ventilating and Air conditioning) systems using which you can ensure thermal performance and design quality at the start—and avoid costly rework later on. HVAC studies are generally carried out to analyse the thermal comfort, ventilation for people in various living or working environment (such as office, buses, houses etc). Some additional capabilities include:
• Human comfort factors—helps to calculate 8 comfort parameters [“Predicted mean vote” (PMV) and “Predicted percent dissatisfied” (PPD)] to measure thermal comfort and identify potential problem areas
• Advanced radiation—helps to determine the model absorption of radiation in solid bodies and definition of the radiation spectrum for a more accurate radiation simulation
• Tracer study— analyze the flow of a certain admixture (tracer) in the existing carrier fluid
