Abstract: This paper studies the dynamic modeling of a nonholonomic mobile manipulator that consists of a multi-degree of freedom serial manipulator and an autonomous wheeled mobile platform. The manipulator ...

Abstract: The dynamic balancing of flexible linkages, which is a challenging topic in the dynamics of mechanisms, is accomplished by active control with redundant drives for the first time in the present ...

Abstract: With the Timoshenko beam theory and the Finite Element Method, the dynamic equation of planar cooperative manipulators with link flexibility is proposed in absolute coordinates. Taking the actual ...

Abstract: Experiments are performed to actively suppress vibration of a flexible four-bar linkage mechanism bonded with piezoelectric materials as sensor and actuator. The control system is built up with ...

Abstract: An optimal model is developed for determining the well sites and their pumping rates from the upper aquifer and lower aquifer in a two-aquifer system, which is designed to prevent the water quality in lower aquifer from ...

Abstract: Freezing in saturated saline soil is a dynamic, coupled hydraulic-thermal-salt-mechanical (HSTM) process. The aim of this paper is to establish a model to describe the coupling process. In the model, mass conservation law, ...

Abstract: Based on the principle of dynamic equivalence, a new dynamic model of compliant mechanisms is developed using the pseudo-rigid-body model. The dynamic equation of general planar compliant mechanisms ...

Abstract: Experiments were carried out to gain insight into the effect of inherent factors on the radiolytic degradation of two biorefractory contaminants, Acid Orange 7 (AO7) and nitrobenzene (NB). The effects of irradiation dose rate

Abstract: Hydrogels have a large number of potential applications in microelectromechanical technology as sensors and actuators. In this paper we try to understand the physics of dissolvable hydrogels and investigate the various ...

Abstract: Two feldspars were used as fine aggregates and cement replacement to explore the effect of feldspar dissolution on alkali–silica reaction (ASR) expansion at elevated temperatures (38°C and 60°C). At elevated temperatures, ...
