This paper aims at the novel approach to establish the equation of the motion of the piezoelectric energy harvester. The energy harvester is composed of three beams, two masses and two joints. Each joint is modeled as a spring and a damper. Since two of the three beams are identical in geometry and deflection, the device is actually a 2-DOF vibration system with 2 natural frequencies. With comparing...
In order to ensure space manipulator operates safely and reliably, dependable locking and fixing is necessary before launching. Thus, locking and fixing of space manipulator is extremely important. Optimized number and position of locked points are needed while locking and fixing. Based on the number of manipulator's locked points and position's disposal method and finite theory, the system first-order...
