e3k engineers can predict the motion of machine parts and objects using both equations of motion and computer simulation. Solidworks Motion is an advanced 3D software package which can be used to simulate moving parts and the resultant forces and can also determine reaction forces and resulting motion from impacts using exact geometry and coefficients of restitution.
Forces predicted using motion analysis can also be used in other simulations such as Finite Element Analysis (FEA) to predict the stresses in the interacting objects.
Motion Simulation Case Studies
Novel Combustion Cycle Development
e3k undertook a complete research, design, commissioning and testing program of a novel two-stroke direct-injection engine. The engine utilised a non-sinusoidal piston motion profile. Motion simulations were used to ensure component contact was maintained between the reciprocating and rotating components during rapid acceleration events.
A motorcycle rider lost control when the vehicle hit a bump in the road. e3k used a series of Solidworks motion studies to determine the likely speed of the motorcycle at the time of the incident.
Helicopter Drivetrain Simulation
As part of an investigation into a helicopter crash, e3k engineers created a 3D motion analysis of the drivetrain of the helicopter, including the flex plate. The simulation was used to confirm our theories on the cause of some of the damage to the flex plate.
A Rugby ball shaped rock was struck by a vehicle travelling at 100km/h. It was claimed that the rock rolled and bounced high off the bitumen road, striking another vehicle and injuring one of the occupants. Gilmore Engineers used advanced computer simulation to map the potential path of the rock showing that the bouncing motion was indeed possible, and was much like that of a Rugby ball.
Australian Standard Simulations
e3k designed a new height adjustable desk for use in both sitting and standing modes. As part of the design process e3k engineers used FEA and advanced motion simulation to predict the performance of the desk when subject to Australian Standards tests.
Smart Lock Performance Improvement
e3k were asked to solve a problem with the performance of a smart locking device. As part of the investigation, e3k performed a motion analysis on the whole assembly to see how the components interacted when the unlocking mechanism was triggered.
