RE: Titanium Valve springs
resilience = σ2max / 2E
Maximizing the material strength and minimizing the elastic modulus creates a spring with the maximum resilience (elastic energy absorption).
RE: Titanium Valve springs
Can you give more info what are the demands from the spring such as:
1. Length at first loading point and the respective force
2. Length at the second loading point and the force.
3. Desired spring outside diemeter.
4. Working temperature
5. The type of titanium wire alloy (spec)
6. Frequency of loading etc.
RE: Titanium Valve springs
Has some made Titanium springs that operate in the conditions seen on the top end of a motorcycle engine.
RE: Titanium Valve springs
If you are not familiar with current titanium valve spring applications (e.g. racing vehicles), then yes, you may have missed something. You are right that titanium will gall (which is why titanium valves have coatings to minimize galling), but that hasn't been a big problem with springs.

RE: Titanium Valve springs
Thanks for bringing me up to speed. The last time I checked they were still struggling with the Titanium spring problem. Still learning things even in my old age even if I can’t keep up with the information age.
Good luck to "morepower" in his quest for speed.
I onced owned a KHRM bike. I probably couln't crank it today.
RE: Titanium Valve springs
I have formula's here for checking surge in springs but I would need all the info you have like space envelope that the spring can fit into and the forces and deflections the spring is liable too encounter.

RE: Titanium Valve springs
-In regards to titanium rubbing. Does the issue need to be addressed when the end coil touch the active coil on compression?
-If the rubbing is an issue what coating can be used to reduce damage that would cause fatigue? Since I'm designing these springs for suspension use, I could add some rubber insert/bumper on the coil ends.
-What are the material designations/specification for titanium springs wire?
-I'm currently working on compression springs for shock absorbers and found this forum. Thanks in advance any suggestions you guys provide.
