simulating a simple spinning blade (mower)

prefetch — Sun, 12 May 2019 23:18:35 GMT

i'm trying to figure out an approach to simulating a trimming device (like a weed eater or lawn mower.)

i've created a super simple representation of one, and recorded a video of it - but for some reason the audio didn't record.

the spinning blade rotates on a fixed axle. it spins around, but there is an obstruction in the way. i want to run a simulation to see the weak point in the design in the scenario that it hits a hard obstruction (like a rock, or a concrete curb.)

i've tried static stress, non-linear static stress and event simulation, and i keep running into various problems - either i can't get the blade to spin, or the simulation errors out.

could someone give me some guidance about how to approach this?

Event simulation with an initial velocity. Not sure if it can be set to an angular velocity though as I've never tried it.

unfortunately the initial velocity setting in an event simulation doesn't help. it doesn't seem like there is a concept of rotation. i can only give a direction vector on a face.

so...there's no way to simulate a rotating thing during an event...??

Yeah, this is great information. I have to try for this.
