Nowadays, the CAN bus technology has become a popular communication way in more vehicles. Each electronic control unit in the automotive control network based on CAN bus can be regarded as an intelligent node, in which ID address, bitrates, work mode, etc. are set through programming. In this paper, the hardware rationale and the control software of the(More)
Circular wobbling motion of the stator head of a cylindrical type ultrasonic motor was simplified as revolution of a rigid body about a fixed point, by considering the motion and structural characteristics of the stator. The dynamic model of the stator was established by using the Euler angles and Euler dynamics theory. The complete dynamic model of the(More)
Edge effect was found in plasma arc forming process of sheet metal, which reduces the forming accuracy of sheet metal seriously. In order to reveal the forming mechanism and forming laws of the edge effect. A numerical model on forming of sheet metal using plasma arc with scanning along a straight line was established and the forming mechanism and forming(More)
In the past, most robots used the centralized control mode, in which the power electronics, the motor controllers and the coordinating computer were contained in a central control box. This paper describes the design of a distributed robot control system which consists of the host computer, the controller for each joint and the communication network. The(More)
When flexible forming of sheet metal using plasma arc scanning along a straight line, we find that the forming edge appears warping deformation and the bending angle varies along the scanning path, the phenomenas are defined as edge effects, which will reduce the accuracy of forming of sheet metal seriously. The edge effects and its formation laws that(More)
In order to measure the load characteristics of a bar type ultrasonic motor quickly and accurately, a test system of mechanical properties of ultrasonic motor was developed based on the measurement principle of load characteristics estimated indirectly according to transient response. The system can be used to measure the transient response of ultrasonic(More)
