A powerlock is used to transmit torque between two shafts, to protect important equipment from overloads, and to compensate for the misalignment of assembled shafts. In this study, the effect of the shapes of the inner rings, bolt-fastening force, and friction on power transmission performance of powerlocks is investigated. Finite element analysis and experiments were conducted for two cases, and the analysis results were validated. Analyses were carried out for inner rings of various shapes and for various values of boltfastening force and friction coefficient. The main factors that affect the torque transmission performance were investigated based on the analysis results. © 2017 The Korean Society of Mechanical Engineers.

Recently, the proportion of electronic components is increasing in the automotive vehicle. To protect electronic devices is extremely important in the car driving and maintenance. The fuse box of vehicle has functions to protect the circuit and device when the devices experience an excess current. Also, it is installed in the engine room of the vehicle and experience complex loads such like vibration from the ground, temperature from circumstance and electronic current. The objective of this study is to predict the fatigue lifetime of fuse box under complex environment such like vibration, electronic and heat load. To verify the simulation model of fuse box, various simulations to describe the physical test conditions were performed. And the results of simulation were compared with the test results. One single simulation model was used for the simulations in the different field problem. The stress results from vibration and electro-heat-mechanical coupled simulation were used to calculate the fatigue lifetime of the fuse box components. Finally, the results from fatigue lifetime simulation of the fuse box under complex environment are presented and compared with test results. It also examined the effect of wire bundles.

In this paper, a passive filter is proposed to support a star-like topology in a high-speed controller area network and to extend the length of the stubs. A high-speed controller area network requires a linear wiring topology, while an actual network may be configured as a star-like structure using joint connectors owing to productivity and cost concerns. This joint-connector-based controller area network configuration is likely to suffer from increased signal distortions caused by a larger transient voltage and impedance mismatch. Here, a passive filter for reducing these signal distortions in a joint-connector-based controller area network structure is proposed, which allows a star-like topology with extended stubs. The proposed passive filter is composed of a resistor and bead in series, which is easily inserted in a joint connector. With the proposed filter, the induced transient voltage and settling time in transition to a recessive state were reduced by 37% and 66% respectively. Thus, the proposed filter has the effect of improving the reliability of communication in the same wiring dimension or, equivalently, lengthening the stubs with the same reliability. © 2013 IMechE.
