Hey all,
I solved the problem by picking two different springs of different material. This way, at high temperatures, the difference in spring rate change between the two compensates for the overall decrease in spring rate. Thanks.
I'm running into a problem where I need to make a spring out of a material whose modulus doesn't change much with temperature (up to ~130C). I have a part suspended between two springs, so the spring preloads are not important, only the spring rate (and the spring rate is directly related to the...
