Systematic errors might include consistent deviations due to material property assumptions, while random errors could arise from fluctuating environmental conditions.
  3. Quantify Individual Errors: Quantify the magnitude of each identified error source. This may involve using experimental data, literature values, or sensitivity analysis to estimate the impact of each error on the system. For example, if the assignment involves kinematic coupling, you might quantify the error due to the compliance of the coupling components by comparing theoretical predictions with experimental measurements.
  4. Combine Errors: Use appropriate methods to combine individual errors to estimate the overall error in the system. Common methods include root sum square (RSS) for combining independent errors and direct summation for dependent errors. The combined error gives an overall measure of the uncertainty in the system's response.
  5. Analyze Compliance Errors: Specifically analyze compliance errors, which are errors due to the deformation or flexibility of components under load. Compare the compliance of different parts of the system, such as the kinematic coupling versus the frame. For example, calculate the deformation due to kinematic coupling compliance and frame compliance separately and determine their relative contributions to the total error.
  6. Calculate Error Percentages: Determine the percentage of error attributed to different sources. This helps in understanding the dominant sources of error and prioritizing efforts to mitigate them. For instance, if the error due to kinematic coupling compliance is significantly higher than frame compliance, focus on improving the coupling design.
  7. Perform Sensitivity Analysis: Conduct a sensitivity analysis to see how changes in key parameters affect the overall error. This involves varying parameters such as material properties, geometric dimensions, and load conditions to see how sensitive the system's response is to these changes. Sensitivity analysis helps identify which parameters most significantly influence the error.
