Design plan of the smart devices(including smart sensors and smart actuators) based on D.

This paper introduces a new design scheme of intelligent electric-actuator, makes the intelligent electric-actuator become a field devices which have the functions of network and communication in the filed-bus control system.

This paper intro- duces a new design scheme of intelligent electric-actuator,makes the intelligent electric-actuator become a field devices which have the functions of network and communication in the filed-bus control system.

Because of this, this paper presents an intelligent electrical actuator, which not only expands the cont.

Design of intelligent actuator based on DeviceNet;

So an effective intelligent actuator based on AL (Artificial Life) will be designed to show the kinetic and physiological characteristics of the artificial leg.

An intelligent executive based on model for autonomous spacecrafts is a goal-driven commanding system that estimates current spacecraft modes,detects and repairs failures.

The executive mechanism of Cu-Al pipe butt welder,based on above,was designed,including its air system and mating clamper.

In order to improve the running smoothness of mesh-belt and reduce the wear between mesh-belt and traction wheel, on the base of completing the design scheme of mechanical system in heat treatment furnace with mesh-belt conveyer, the dimension synthesis of the executive mechanism is accomplished and the main sizes of the mechanism are given.

For the swinging cylinder type of hydraulic wrench, through the analysis and calculation for the locating parameters of its executive mechanism, formula and design precondition of the locating parameters are presented, with which the minimum of pushing force of the oil cylinder can be achieved under definite swinging angle and given loosening & tightening torque for the fasteners.
