Linkage synthesis includes three types of task specifications, which are motion generation, function generation and path generation. Generally, the three syntheses are treated separately. However, in some situations, linkage needs to complete two types of tasks, called hybrid tasks, simultaneously. In this paper, we present an analytical method to synthesize a multi-functional eight-bar linkage with a translational actuator to complete a hybrid task. The linkage can pass through 5 task positions for function generation and 5 task positions for motion generation simultaneously. To avoid highly nonlinear polynomial design equations, the linkage is separated into three loops to synthesize. The strategy of kinematic performance verification is proposed to obtain a non-defect linkage. Finally, a novel variable wing sweep mechanism for unmanned air vehicle is designed by using the multi-functional eight-bar linkage, which also validates the hybrid synthesis method. The result of this study provides a new design idea for linkage design.
