Embodiment 1

[0118] like Figure 4 As shown, the embodiment of the present invention takes a four-degree-of-freedom articulated robot as an example to describe the system and method for analysis and control of robot coupling dynamic characteristics of the present invention.

[0119] In this embodiment, the drive system of the selected four-degree-of-freedom articulated robot is driven by the motor 1, and the electromagnetic parameters of the drive system interact with the mechanical parameters to form the electromechanical coupling of the system. Transmission system 2 adopts gears or other transmission joints, and rigid-flexible coupling exists in the transmission process. The end articulated arm 3-1 of the actuator 3 is fixed with the end effector 4, and the end effector 4 is used to grab the load 8, and the end articulated arm 3-1 generates elasticity during the operation or during the motion conversion process and sudden stop Vibration affects the operation accuracy and stability of th...

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a system and method for analysis and control of robot coupling dynamic characteristics. Background technique [0002] Industrial robots are widely used in machining, loading and unloading, spraying and other operations. During the operation, the robot system needs to maintain good dynamic performance and operation accuracy. At present, the degree of integration of the robot system is getting higher and higher, which will inevitably increase the coupling between the system components (such as the drive unit, sensor unit, control unit, transmission mechanism and actuator of the system). For high-power heavy-duty robots, the coupling effect among the drive unit, transmission mechanism and actuator of the system, especially the electromechanical coupling factors of the drive system, has a more obvious influence on the dynamic characteristics of the system. When performing high-speed ...
