Variable pitch spring calculations

AI Thread Summary
Calculating the spring constant of a variable pitch spring under compression is complex due to the changing stiffness as coils become inactive. The spring's effective stiffness increases with compression, necessitating a specific equation to determine the new spring constant after compression by a distance x. Resources such as academic papers on variable stiffness coil springs, particularly in vehicle applications, can provide insights and methodologies for these calculations. The discussion emphasizes the need for precise formulas to account for the unique behavior of variable pitch springs. Understanding these calculations is crucial for optimizing designs in engineering applications.

Hi,
does anyone know how to calculate the current spring constant of a variable pitch spring when under compression. Since some of its coils get inactive when compressed the stiffness is increasing and consequently “k” is changing as well, is there an equation I can use to calculate the new spring value after the spring is compressed by a distance x?

Thread 'Turbocharging carbureted petrol 2 stroke engines'

Hi everyone, online I ve seen some images about 2 stroke carbureted turbo (motorcycle derivation engine). Now.. In the past in this forum some members spoke about turbocharging 2 stroke but not in sufficient detail. The intake and the exhaust are open at the same time and there are no valves like a 4 stroke. But if you search online you can find carbureted 2stroke turbo sled or the Am6 turbo. The question is: Is really possible turbocharge a 2 stroke carburated(NOT EFI)petrol engine and...

Thread 'HP Required to move a robot 10meters at 1.5m/sec'

I need some assistance with calculating hp requirements for moving a load. - The 4000lb load is resting on ball bearing rails so friction is effectively zero and will be covered by my added power contingencies. Load: 4000lbs Distance to travel: 10 meters. Time to Travel: 7.5 seconds Need to accelerate the load from a stop to a nominal speed then decelerate coming to a stop. My power delivery method will be a gearmotor driving a gear rack. - I suspect the pinion gear to be about 3-4in in...
