Stability and reliability are the essential properties for the control system of the no stroboscopic medical shadowless lamp. This paper designs an intelligent control system based on STM32F103 for medical shadowless lamp. PWM (Pulse Width Modulation) control technique is utilized to realize the no stroboscopic work and rapid multistep regulation. By detecting the working condition of shadowless lamp...
Circular truss antenna is a new form of satellite antenna, where is the key deployment trend to the satellite. The truss elements, including some key components such as Sync hinge joint, T hinge joint, and bars, are the basic units to build the circular truss. Failure mode, effects and criticality analysis (FMECA) for the key components of the circular truss is given in the paper.
The kinematics accuracy of a mechanism is one of the key issues in the design of high speed press. In this study, a universal accuracy analytical model of planar linkage mechanism is established based on matrix analysis, and the calculation model for kinematic accuracy reliability index of linkage mechanisms is built in terms of the state function of reliability. Aiming at highspeed press mechanism,...
