hi,
i am trying to use BMX to design a spring linkage that has a specific leverage ratio that varies throughout the linkage's range of motion.
i've created a skeleton model of the linkage with all the measurement analysis features that define the leverage ratio of the mechanism and also made a parameter (using a polynomial expression) that defines the graph of the desired leverage ratio, all driven by the spring length dimension. the problem is i don't know what analysis to run to optimize the linkage dimensions to get the leverage ratio curve that most closely matches the desired curve throughout the desired range. is this an optimization? if so, how do i set a range for the driving dimension (spring length)? is it a multi-objective design study? how would i go about doing it?
is this possible with BMX? i also have MDO if needed.
thanks,
chris
