The kinematics analysis on single cross universal joint

A new method of space analytic geometry is presented, by which the kinematics characteristics of single cross universal joint is analyzed. Compared with traditional method such as descriptive geometry, three element complex and multi-body system dynamics, space analytic geometry has characteristics of brachylogy and understandability. It is a more convenient way to analyze the kinematics characteristics of single cross universal joint and suitable for project design. The Matlab software is used for simulation to analyze kinematics characteristics of rotate speed and angular acceleration of cross universal joint driven fork shaft.
