    摘要: A multi-axis fatigue testing device includes a multi-axis test fixture having a multiple input, multiple output mechanical linkage driven by a plurality of actuators and a controller operating each of the plurality of actuators in real time and in synchronization to produce user-defined multiple fatigue cycle profiles. At least one of the actuators driving the mechanical linkage acts against an artificial load characterized by a stiffness. The stiffness is selected to increase a resonance frequency of the test fixture to allow fatigue testing at higher frequencies for a wider range of samples.

    摘要: Stability of a control system for a materials testing system using specified filter parameters is confirmed by inputting to the control system a test signal having a predetermined waveform, automatically monitoring the output of the materials testing system, and automatically comparing the output to a threshold. If the output exceeds the threshold, a first action is taken. If the output does not exceed the threshold, input of a command signal to the control system is permitted.

    摘要: A disc drive head actuator includes a suspension structure and a slider integrated with the suspension structure. The actuator is one of at least two actuator assemblies batch-fabricated on a common substrate. The head actuator may be fabricated using mircofabrication techniques. The head actuator may have a reduced size, including package height relative to conventionally manufactured disc drives. Using mircofabrication and/or batch fabrication techniques provides reduced tolerances, which allows for increased actuation forces and/or reduced power consumption. Some embodiments include four-bar linkage actuators, which increase lateral stiffness of the actuator, allowing for a precise motion of the head relative to a media surface.
