Event based motion is part of SOLIDWORKS Motion Add-In. It
is a powerful tool that allows to link sensors with actuators and simulate
synchronous motion patterns present in various mechatronics devices.
Event Based Motion offers the following benefits:
- It is possible to simulate operation of
electronically controlled mechanisms, such as manufacturing and lab equipment.
Results obtained from the study allow to check whether the mechanism is going
to work as intended. Detailed reaction force/torque results can be extracted
like in any other SOLIDWORKS Motion study.
- Creating marketing/presentation videos becomes
much easier as software takes on the job of creating animation key frames for
you. Key frames are created during the simulation run.
In this example a self-playing pinball machine was created
and simulated using event based motion.
The table was created using a single master part and ‘Save
Bodies’ command, that automates assembly creation by turning solid bodies into
part documents and arranging them inside a new assembly document. This is a
common method of top down assembly modelling using a multi body approach.
The table was fixed in an inclined position. Two copies of
paddle part were brought into the assembly and their initial orientations were
set. Two rotary servo-motors were attached to paddle axes and one linear servo
was attached to the plunger.
Each servo has been assigned with a proximity sensor – to
trigger motion when the ball passes close to the paddle/plunger.
Motion analysis was set to 1000 frames per second to avoid
numerical errors that end up with the ball flying through walls. Gravity was added to put everything in motion.
The events setup is listed in event manager below:
