Your Partner for Dynamic and Fatigue Tests

The level and complexity of product reliability and safety requirements have been increasing in many industrial elds. Complying with such requirements requires performing a wide variety of tests and evaluations at each stage of production, from research and development of materials to evaluation of nished products. Materials and parts can sometimes form cracks from repeated exposure to even small forces and, in the worst case, even completely fail. Therefore, for products that are exposed to repetitive loads, such as automobiles, mobile phones and other frequently handled items, and arti cial bones and other biological materials or implants, it is essential that materials, parts, and nished products be evaluated by dynamic/fatigue testing and endurance/reliability testing. In addition, to more closely approximate actual usage conditions, an increasing number of tests used in research and development of various materials with special functional properties require more complicated and accurate control or measurement methods. Therefore, Shimadzu offers a wide variety of testing machines that can be con gured to satisfy increasingly sophisticated and diverse evaluation and testing requirements in a wide range of elds.

Autotuning and Automatic Gain Control Functions

Two-Degree-of-Freedom PID Control Minimizes Effects from External Disturbances

The control method (two-degree-of-freedom PID control) is able to optimize the target response for specified signals and the response to external noise. Optimizing the control parameters using the autotuning feature helps maximize the system performance. The 24-bit high-resolution measurement function and 10 kHz high-speed feedback ensure even sharp changes in test force or stroke can be controlled reliably.

Autotuning Function

The autotuning function accurately reproduces target waveforms by automatically determining optimal control parameters. Simply set up the sample in a similar state as for the intended testing and then specify the preload. Then the function automatically tunes the manually adjusted control parameters.

Measures Even Slight Differences in Performance

Dynamic testing machines apply a load waveform to a product and measure the corresponding response. The precise and reliable waveform input provided by Shimadzu dynamic testing machines and controllers allows identification of even slight differences in product performance and helps provide feedback for product design.

For example …

A variety of parts is used to achieve a comfortable ride in automobiles. To improve the performance of those parts, data from evaluating their characteristics is essential. Therefore, the damping force is measured as test frequency is varied. Shock absorber performance can be confirmed by measuring the relationship between velocity and damping force or the response to a Lissajous or other waveform. The input waveform is important for evaluating slight differences in performance.

Impressive Waveform Reproducibility

The 10 kHz high-speed feedback and 24-bit high resolution provides highly precise control waveforms for all measurement ranges.
Tests can be done with accurately controlled waveforms even in cases where the frequency of the input waveform varies, such for assemblies or finished products, or If tests are affected by servo valve frequency characteristics or PID control settings are inadequate, then the amplitude can vary depending on the frequency, as shown above. However, the frequency-sweep AGC function corrects the amplitude to keep it constant at all frequency levels.

Accurately Reproduces Actual Operating Waveforms

The Servo Controller 4830 has a waveform correction function that helps accurately reproduce input waveforms. Used in combination with various additional software, it can be used to simulate actual operating waveforms determined by measuring the status of actual loads or simulate the most severe conditions by continuously applying loads at the resonant frequency. The Servo Controller 4830 optimizes actuator control based on various testing requirements to enable highly precise and accurate testing.

Waveform Distortion Correction

This function makes it possible to correct the waveform based on the frequency characteristics of the loading mechanism (transfer function correction), which helps achieve the intended target waveform. Because it can correct for loading mechanism-specific periodic strain, it can cancel out unwanted strain components and accurately control loads according to the target waveform. Complicated actual loading profiles that were difficult to simulate can now be specified easily using this controller and software.

Guaranteeing Endurance

Simulates the Most Severe Loading Conditions Using the Resonance Frequency Tracking Testing
To guarantee product endurance, the resonance frequency is input because it results in the highest load levels. The resonance frequency can be determined in only a few seconds. It can also be automatically tracked if it changes due to sample fatigue. This reduces the labor required to manually specify the resonance frequency and the stress on samples.
