Solidworks design problem: Racing sim crankset

3D Design Assembly

Hello

I want to modify my Racing T3PA Pro crankset by adding a Load Cell force sensor + an elastomer-based shock absorber inspired by this crankset: heusinkveld engineering ultimate pedal.

The general idea is to use commercial parts or limit the number of custom parts ordered online. Operation, the foot pedal compresses the elastomers and the effort and transmits to the Load Cell sensor.

Modeling from the real: Base, pedal (pedal support, pedal cleat, pedal), Sensor and its drillings, pedal stroke with a rotation range constraint in degrees.

Parts created: Screed, rubber.

 

I dry on the modeling of the groove stress which imposes a right angle between the rubber axis and the groove as well as on the positioning of the sensor. I don't have an idea to carry out the transmission of power simply on the sensor via a turntable.

The sensor has 2 holes and it is to this point that the force must be transmitted.

 

Do you have any ideas?

After the modification, I would like to do a dynamic study, to size my elastomers because, the sensor is a max 20kg force sensor, so see with the lever arm of the pedal how much force to apply on the pedal corresponds to.

 

Thank you.

 

EDIT: By putting a Tangeante and NON groove stress between the rubber and the groove, it works, that is to say that I can have a sensor face relatively parallel to the rubber face and the rubber axis is free, but it does not stop at the bottom of the groove. What to do????

So, first thing, putting a sldasm file without its parts is useless, you either have to do a pack&go or make the parts virtual.
Second, not everyone has the same version of SW, so it's a good idea to take screenshots.

There is no need to do a dynamic study to size the elastomer, we are on a simple wheelbarrow-type force calculation.

Thank you for your answer, here are the screenshots.

I modified my design in the meantime compared to the first message, since I was blocking with the groove, I had put the grooved guide from the front as the sensor support but it didn't work. I don't understand how the HE pedalboard can slide with the fixed part drilled???

Precision, the sensor must be fixed on one side and the stress on the other side

Thank you for your design advice.

Any idea?
