Total Number of Turns of Engine Valve Spring given Maximum Compression in Spring evaluator uses Total Coils in Valve Spring = (Modulus of Rigidity of Valve Spring*Wire Diameter of Valve Spring^4*Maximum Compression in Valve Spring)/(8*Axial Force on Valve Spring*Mean Coil Diameter of Valve Spring^3)+2 to evaluate the Total Coils in Valve Spring, Total Number of turns of engine valve spring given maximum compression in spring is the total number of coils or turns of the engine valve spring including the coils at the ends of the spring. These end support coils do not contribute to the load-bearing capacity of the spring. Total Coils in Valve Spring is denoted by Nt symbol.
How to evaluate Total Number of Turns of Engine Valve Spring given Maximum Compression in Spring using this online evaluator? To use this online evaluator for Total Number of Turns of Engine Valve Spring given Maximum Compression in Spring, enter Modulus of Rigidity of Valve Spring (G), Wire Diameter of Valve Spring (dw), Maximum Compression in Valve Spring (x), Axial Force on Valve Spring (P) & Mean Coil Diameter of Valve Spring (D) and hit the calculate button.
