Study on Elastic Dynamic Model for the Clamping Mechanism of High-Speed Precision Injection Molding Machine

open access: yesShock and Vibration, 2015
This work centered on the double-toggle clamping mechanism with diagonal-five points for the high-speed precise plastic injection machine. Based on Lagrange equations, the differential equations of motion for the beam elements are established, in a ...

Kineto-static analysis of a hybrid manipulator consisting of rigid and flexible limbs with locking function for planar shape morphing

open access: yesMechanism and Machine Theory
The incorporation of lockable passive backbones into active compliant morphing systems efficiently results in lightweight, high-load, and large deformation systems. However, there exist challenges in kineto-static analysis due to the interaction between rigid reconfigurable kinematic constraints and the nonlinear deformation of actuated flexible limbs.

The Heligoland Glacitectonic Complex in the southeastern North Sea: indicators of a pre‐ or early‐Elsterian ice margin

open access: yesBoreas, Volume 51, Issue 1, Page 100-117, January 2022., 2022
Glacial landforms are abundant in the North Sea basin and are often used to reconstruct the impact and dynamics of ice sheets during the Pleistocene. Geophysical methods have allowed the mapping and structural analysis of glacial landforms at the surface and in the subsurface to estimate the position of former ice margins in the North Sea. However, the

Reducing the Frame Vibration of Delta Robot in Pick and Place Application: An Acceleration Profile Optimization Approach

open access: yesShock and Vibration, Volume 2018, Issue 1, 2018., 2018
Delta robot is typically mounted on a frame and performs high speed pick and place tasks from top to bottom. Because of its outstanding accelerating capability and higher center of mass, the Delta robot can generate significant frame vibration. Existing trajectory smoothing methods mainly focus on vibration reduction for the robot instead of the frame,

Active Vibration Control and Coupled Vibration Analysis of a Parallel Manipulator with Multiple Flexible Links

open access: yesShock and Vibration, Volume 2016, Issue 1, 2016., 2016
This paper addresses the active vibration control and coupled vibration analysis of a planar parallel manipulator (PPM) with three flexible links. Multiple piezoelectric ceramic transducers are integrated with the flexible links to constitute the smart beam structures, and hence the vibration of the flexible link can be self‐sensed and self‐controlled.

Active Vibration Suppression of a 3‐DOF Flexible Parallel Manipulator Using Efficient Modal Control

open access: yesShock and Vibration, Volume 2014, Issue 1, 2014., 2014
This paper addresses the dynamic modeling and efficient modal control of a planar parallel manipulator (PPM) with three flexible linkages actuated by linear ultrasonic motors (LUSM). To achieve active vibration control, multiple lead zirconate titanate (PZT) transducers are mounted on the flexible links as vibration sensors and actuators.
