Result Interpretation

Sheet Gasket Joint Relaxation Compensation Torque Adjustment calculator computes Compensatory Torque Increase in N·m using the defined engineering formula and the input values provided. Compensatory Torque Increase is expressed in N·m. No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

  • Initial Bolt Preload Force = 4000
  • Bolt Nominal Diameter = 0.01
  • Joint Settling Time = 0
  • Torque Efficiency Factor = 0.1
  • Relaxation Coefficient = 0.2
  • Relaxation Rate Constant = 0.0001

Expected Result:

  • Compensatory Torque Increase = 0

Engineering Interpretation:

Under the given input conditions, the calculated result is: Compensatory Torque Increase = 0 N·m.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.

Formula / Method

compensatory torque increase = relaxation coefficient * initial bolt preload force * bolt nominal diameter * (1 - exp(-relaxation rate constant * joint settling time)) / torque efficiency factor
