Sample Simulations
Manufacturing
screw rolling
The external threads of a screw are formed by rolling die. This simulation includes large material deformation and complex contact surfaces. The video shows the stress distribution during the process. The regular rolling die can be replaced by special designed rolling die for screws / bolts with special external threads.
plastic injection modeling
The video shows the process of a plastic injection modeling. The plastic flow in the entire die is clearly simulated throughout the injection cycle.
magnetic pulse welding
In this simulation, an aluminum tube is deformed and welded on a steel rod by electromagnetic forces. The video also shows the stress distribution of aluminum and steel parts during the process.
Ultrasonic Welding
There are four parts in this simulation ordering from top to bottom: a tool, two metal sheets, and an anvil. This video shows the changes in temperature distribution in the metal sheets. The simulation can help engineers decide pressure, frequency, material, and size of sheets for ultrasonic welding. Moreover, it can help engineers design tool shapes.
Product Testing
smart Phone dropping
A smart phone is dropped from a desk. The simple model focuses on the phone’s surfaces (Al alloy case and tempered glass). The video shows the motion during phone dropping and Al phone case suffers deformation / damage after the phone is dropped. The glass has no damage in this simulation.
Fatigue test
This model is a riveted lap joint in a random vibration environment. This video shows the cumulative fatigue damage ration. The fatigue life is also available throughout the simulation.
eigenvalue / eigenmode
This is the simulation of vibration modes for a preloaded (tension) metal part. The video shows the 2nd eigenmode. All eigenvalue and their modes are available from this simulation.
Boat
This simulation shows a stationary boat being pushed by waves in the middle of a sea. This kind of simulation can help engineers design the hull (material, shape, structures, etc.).
Lap-Joint Plate Tensile Test
Two metal plates are jointed by a rivet that is subjected to tensile force and resulted in deformation. This video also shows the stress distribution of metal plates.
Design
Central ac
This model is a central AC system in a common 2 bedrooms and 2 bathrooms condo unit. There are 1 vent in each bedroom, living room, and kitchen. The simulation only focuses on the AC duct, so the condo floor plan is for reference. The video shows the air velocity in the AC system, which can help to design the dimension/route of duct and to decide the capacity of central AC unit.
Wind Turbine
This video shows the flow field of a vertical wind turbine. The colors of streamlines represent the fluid velocity. This simulation can help designer to improve the efficiency of wind turbine by changing the dimensions, structures, and materials while maintaining the strength of the structure.
Split AC
This simulation shows the temperature distribution in a room after turning on a split AC. The room is assumed to be seamless to simplify the simulation. This kind of simulation can help people when selecting capacity, location, and vent direction of a split AC system.
Researching
Friction stir process
A rotating tool penetrates into Mg & Al alloy sheets by friction heat – this is one kind of Friction Stir Welding (FSW) process. The model has extreme large deformation and heat generation / transfer. This video shows the distribution of temperature during FSW process.
Railgun shooting
In this simulation, the electromagnetic force launches the armature in rails and the armature pushes the projectile and its shell. Moreover, the shell detaches from the projectile due to air resistance after launch.
Free fall
A ball falls into fluid and generates a wave. The velocity of the ball and the flow of the fluid are available from this simulation.
Galvanic Corrosion
In this model, a Mg rivet (left) and a Al rivet (right) are fixed on a stainless steel plate. This video shows the distribution of current density due to potential difference of dissimilar metals. This distribution can be used to predict the corrosion rate of materials.
