Dynamic Characteristics of Parallel Linkage Pendulums

SAE Technical Paper Series, 1976
<div class="htmlview paragraph">Many impact tests use some type of pendulum. For example, the compliance test of Federal Motor Vehicle Safety Standard No. 215, the bumper standard of automobiles, is usually conducted by using a parallel linkage pendulum.

Workspace and Singularity of Planar Parallel Linkage

, 2014
The layout of this chapter is that the theoretical foundation for the workspace of planar parallel mechanism under rotational actuations is firstly investigated, and then the algorithms to search the reachable and the dexterous workspaces of such mechanisms are discussed with application examples.

Parallel linkage steering for an automated guided vehicle

IEEE Control Systems Magazine, 1989
The computer-aided design of suitable control strategies for parallel linkage steering of an experimental automated guided vehicle is described. The microprocessor-based steering control system is modeled, and stability characteristics using proportional control are investigated by means of describing functions.

Solar Tracking Parallel Linkage Applicable for All Latitudes

, 2018
In the paper a new concept of a pseudo-equatorial type 2DOF solar tracking mechanism is described. The mechanism is of parallel linkage type based on two kinematic constraints revolute-sphere (RS) which determine an 1 DOF planar loop RSSR with a passive rotation of the coupler.

The Kinematics of a Parallel-Linkage Robot

, 1991
The kinematics of a parallel-linkage robot based on the Stewart platform are analysed. From the desired motion of the tool are derived the linear and angular positions, velocities and accelerations of all parts of the manipulator. The analysis is general, and applies to any fully parallel robot with linear actuators.

Reconfigurable Generalized Parallel Mechanisms with Kinematotropic Linkages

2021 7th International Conference on Mechatronics and Robotics Engineering (ICMRE), 2021
This paper presents a novel idea of designing reconfigurable generalized parallel mechanisms (GPMs) by integrating kinematotropic linkages with coupling sub-chains (CSs) or configurable platforms (CPs). This leads to two brand-new ways of constructing reconfigurable mechanisms.
