A six degrees-of-freedom (DOF) parallel material testing machine (PMTM), which is based on Stewart Platform, is first proposed in this paper. Several essential issues including prototyping, compliant axis determination and controller design are investigated with specific methods or technologies. The compliant axis, along which the proposed machine has a better performance, is determined by the eigenscrew decomposition method. The proposed force controller incorporates the simplified inverse dynamic model output as a model-based portion of the controller and its validity is verified by means of simulations. Evaluation tests are performed to examine the practicability of the proposed controller and to determine the loading accuracy of the PMTM. Tensile tests and preliminary multiaxial loading tests are performed to verify the performance of the proposed PMTM. The experimental results illustrate that the proposed PMTM is capable of performing multiaxial loading tests of materials and thus a suitable candidate for multiaxial material testing machine.

“…Parallel robot has been extensively investigated by virtue of its high force-to-weight proportion, high stiffness and accuracy, low inertia, and its wide spread applications in various fields such as high fidelity simulators and machine tools [4]. As material testing machine, 6-DOF parallel robot has been used in spinal deformation evaluation [5]. However, its application as a material testing machine is rarely reported.…”

A multidimensional loading material testing machine (MLMTM) based on Stewart Platform is proposed in this paper. The kinematic and dynamic characteristics of MLMTM are analyzed, including the influence of universal joint in each limb on dynamic modeling. The dynamic model is established via Kane method, and the control system is founded based on classic PID strategy. Four experiments are performed to examine the validity of proposed dynamic model and control system of the MLMTM, including two uniaxial experiments and two biaxial experiments. Results of these experiments are summarized as well as the capacity of force tracking and load errors are analyzed. The experimental results demonstrate the validity of dynamic model via Kane method and illustrate that the proposed MLMTM is capable of performing multidimensional loading tests.
