Accurate Realization of Follower Motions in High-Speed Cam-Follower Mechanisms
Traditionally, cam-follower systems are designed by assuming a constant camshaft speed. Nevertheless, all cam-follower systems, especially high-speed systems, exhibit some camshaft speed fluctuation (despite the presence of a flywheel) which causes distorted follower motions and subsequent dynamical problems. The authors previously proposed two methods to overcome these problems: (i) the synthe...
متن کاملK-MORPH: Knowledge Morphing via Reconciliation of Contextualized Sub-ontologies
A knowledge-intensive problem is often not solved by an individual knowledge source; rather the solution needs to draw upon multiple, and even heterogeneous, knowledge sources. The synthesis of multiple knowledge sources to derive a ‘comprehensive’ knowledge source is a non-trivial problem. We discuss the need of knowledge morphing, and propose a Semantic Web based framework K-MORPH for derivin...
متن کاملDynamic and Stability Analysis of Flexible Cam-Follower Systems
In this paper, dynamic and stability analysis of a flexible cam-follower system is investigated. Equation of motion is derived considering flexibility of the follower and camshaft. Viscous and Coulomb frictions are considered in the rocker arm pivot. The normalized equation of motion of the system is a 2nd- order differential equation with periodic coefficients. Floquet theory is employed to s...

متن کاملA Computerized Approach for Tolerance Analysis of Disk Cam Mechanisms with a Flat-faced Follower
A computerized approach for analyzing the tolerances in disk cam mechanisms with a flatfaced follower is presented in this paper. Based on the simulated higher-pair contact analysis, the kinematic deviation of the follower motion caused by the tolerance amount of each design parameter can be determined numerically. The method is validated by means of analyzing the case of an eccentric circular ...
