Sensitivity of Design Parameters on the Constant-Force Behavior of Compliant Slider Mechanisms

Abstract

This paper highlights the significance of sensitivity analysis as a basis for the dynamic synthesis of compliant mechanisms. Based on the results obtained from the sensitivity analysis, four models were developed and simulation results show that for model 1, at a frequency of 44.5 rad/s, the mechanism yielded a median force of 135.4N with a force variance of±0.3N, for model 2, at a frequency of 41.5 rad/s, it yielded a median force of 91.9N with a force variance of ±0.4N, for model 3, at a frequency of 35 rad/s, the compliant slider mechanism yielded a median force of 92.7N with a force variance of ±1.8N and for model 4, at a frequency of 44 rad/s, it yielded a median force of 73.4N with a force variance of ±0.3N. The results obtained shows the effectiveness of this method in improving the dynamic behavior of compliant mechanisms and also shows that, depending on what attributes are most desirable, the compliant slider mechanism parameters can be optimized to achieve the desired results.
