A New Method to Analyze Spatial Binary Mechanisms With Spherical Pairs
(The American Society of Mechanical Engineers (ASME), 2007)One of the most popular mathematical tools in the fields of robotics and mechanisms is the Denavit-Hartenberg (DH) notation ( and , 1955, J. Appl. Mech., 77, pp. 215–221). It is valid only ... -
Cumulative Clamp Load Loss Due to a Fully Reversed Cyclic Service Load Acting on an Initially Yielded Bolted Joint System
(The American Society of Mechanical Engineers (ASME), 2007)The amount of clamp load loss due to a fully reversed cyclic service load is determined for a bolted assembly in which the fastener and the joint were both tightened initially beyond their ... -
Objective Function Effect Based Pattern Search—Theoretical Framework Inspired by 3D Component Layout
(The American Society of Mechanical Engineers (ASME), 2007)Though pattern search algorithms have been successfully applied to three-dimensional (3D) component layout problems, a number of unanswered questions remain regarding their parameter tuning. One ... -
Superelement-Based Modeling of Load Distribution in Large-Size Slewing Bearings
(The American Society of Mechanical Engineers (ASME), 2007)The supporting structures in large-size slewing bearings are highly flexible. In order to choose the proper bearing and shape the load-carrying structure one must estimate the distribution of ... -
