In the present paper, we investigate a modified pseudo-rigid-body (MPRB) modeling approach for compliant mechanisms with fixed-guided beam flexures by considering the load-dependent property. The proposed MPRB model provides a more analytical and accurate method to predict the performance characteristics such as deformation capability, stiffness variation, as well as error motions of complaint mechanisms and offers a new look into the design and optimization of beam-based compliant mechanisms.
In the present paper, we investigate a modified pseudo-rigid-body (MPRB) modeling approach for...
