two seat roller coaster design questions

    I am working on a college project to get a roller coaster simulator up and running in a 5 week turnaround. The current plan is to get the universal seat kit from simxperience, purchase a couple of actuators, then build a seat for two people and attach it, and run No Limits 2 in VR. Thoughts?

    If I purchase SCN5 or 6 actuators like from mirai inter-tech, what do I need to interface between them and the computer? Also what options should be chosen for I/O type and shaft tip?

    I know seating two people side-by-side will put a lot more strain on the system, but if needed we can back down to one person. Would SCN6's make more sense for this application or does the 200 mm/s speed really kill simulation capabilities? Does anyone have rough estimates on how heavy a person the seatmover design can handle with SCN5's?

    Is 150mm stroke length over 100mm worth it for such an application?

    This project was sprung on me so I've been trying to read up as much as I can the past couple of days. I'm trying to get a parts list sorted ASAP so I can initiate the funding process in time. Everything is a lot to take in so appreciate your help, feedback, and patience.

    What is the budget available and how realistic do you consider the time frame to be, both in terms of design, skill, and parts avasilabilitye?

    SimCalc will give a basic understanding of the design Vs physics: https://www.xsimulator.net/communit...e-linear-speed-and-forces-of-your-design.270/

    SCNs are generally sued with one person and the SCN6 is a bit more robust, you can check out the SCN FAQ section here though personally I don't think they are the best option: https://www.xsimulator.net/community/faq/scn5-scn6.2/category

    Spring break is coming up where I will be able to dump a lot of time into it, and between the group of us we have the skills necessary. Ordering parts in time is going to be the most difficult part, so we were looking to keep things cheap but also reasonably plug and play.

    I can't seem to switch SimCalc into actuator calculations, have these not been implemented yet?

    I don't think so but the physics and mechanical design aspects are pretty much the same, the mechanical efficiency of an actuator is a little better than worm gears.
