Understanding the various mechanisms of nonlinear mode coupling in micro and nano resonators has become an imminent necessity for their successful implementation in practical applications. However, consistent, repeatable, and flexible experimental procedures to produce nonlinear mode coupling are lacking, and hence research into well-controlled experimental conditions is crucial. Here, we demon...

This paper provides a detailed review of the global/local non-intrusive coupling algorithm. Such method allows to alter a global finite element model, without actually modifying its corresponding numerical operator. We also look into improvements of the initial algorithm (Quasi-Newton and dynamic relaxation), and provide comparisons based on several relevant test cases. Innovative examples and ...

In vehicle design and production, one typically has to deal with flexible components. Simulation of these flexible components as part of a multibody system is especially challenging, if fast simulations up to realtime are demanded. This is the case, e.g., in interactive assembly simulations of cables and hoses. In our work, we use the discrete Cosserat rod model as presented in [1], which is ba...

China possesses a vast territory, and the manual harvesting of blueberries is time-consuming labor-intensive. Due to planting agronomy differences in other countries, needs develop domestic blueberry harvester realize mechanical harvesting. In process, “collision” core problem. Most literature has studied rigid body–rigid body collision, while few authors have rigid–flexible coupling collision ...
