The roller Hourgrass worm transmission has the properties of high efficiency in meshing, high power transmission, large load capability, long working live, and can save nonferrous metal. This paper made deep investigation into the precision conjugate theory for the roller Hourgrass worm transmission. And the forming theory and machining of the worm gear and its cutting tool,---the hob of worm gear, has been researched as well.

Cyber-physical systems denotes a new modeling paradigm that promotes a holistic view on complex systems. These systems have been studied before from various particular perspectives using paradigms like ubiquitous and distributed computing or embedded and hybrid systems. In modeling cyber-physical systems one has to consider the interaction between physics, computation and communication (networking), and a formal framework to study this systems has to be invented. In this paper we develop a formal approach called Hilbertean formal methods to provide a denotational semantics for cyber-physical systems. We combine denotational semantics with an algebraic model for physical processes to model physical causality and observability.
As the cyberspace structure becomes more and more complex, the problems of dynamic network space topology, complex composition structure, large spanning space scale, and a high degree of self-organization are becoming...

This paper has proposed a drive theory for magnetic suspended knitting needles based on the magnetic suspension theory. The feasibility of the principles for suspended-driven needle selection of circular knitting machine has been discussed. The mechanical characteristics of needles under different drive conditions, and the stress analysis of electromagnetic force have been simulated with ANSYS software.

Since early 1983 the College of engineering at West Virginia University has embarked on initiating specific design phases to implement computer-Aided Educational Methods into the curriculum for its engineering students. This paper describes ongoing trends towards implementing these concepts by the College of engineering to include University/Industry collaborations and more specifically efforts by the Department of Mechanical and Aerospace engineering towards the establishment of Integrated computer-Aided Design Laboratory to add extra dimension to the existing Mechanical and Aerospace engineering curriculm.

Actuators based on magnetorheological fluids represent an innovative technology to optimize brakes and clutches. Compared to conventional electromechanical systems, MRF actuators show improved and advanced characteristics featuring a smooth adjustable torque, a fast response time, a noiseless operation and a reduced design space. In the present paper, the authors propose an actuator design for a MRF based clutch combined with an integrated electric drive. The actuator design is a further development with enhanced performances considering the torque capacity. Both functionalities of this actuator can be controlled widely independent due to a suitable adjustment of the magnetic field. Therefore a model and a new control strategy are developed. The capability of this concept is proven by measurements of a new proof-of-concept prototype that provides an appropriated ratio between coupling and motor torque of 5:1. This highly integrated mechatronical actuator system allows the design of innovative applications whereby novel features are feasible.
