Abstract:

The development of a new, high-speed biaxial materials testing facility is described. The machine combines axial and torsional loading, with each independent load axis under closed-loop servo control. A new feature of this facility is the development of a compound linear-torsional hydraulic actuator which reduces the mechanical compliance and backlash inherent in previous systems. The resultant stiffer machine improves the control of deformation or load at high testing speeds. The system components and operating specifications are described. Author
