High load system DDV-25GP for test piece of sheet, plate and bar shapes
Fine load system DDV-01GP for test piece of film, fiber and paint film
This device is one of the simplest and the orthodox-system dynamic visxoelastometers of non-rssonance forced vibration method. The wide temperature range (-150 degree Celsius to 400 degree Celsius) and forced vibration method enables optional selection of testing frequency within 0.01~110 Hz and also measured of strain dispersion. Furhter, many data from one testpiece can be obtained due to possible switching for constant amplitude control or constant load control and wider range of measurement.
At the testing, applying forced vibaration strain to one end of testpiece, ccompute and output the complex modulus (E*), dynamic modulus of elasticity (E'), loss elasticity (E'') and loss tangent (tan δ) which are elasticity function from stress appeared on the testpiece. These functions of high polymer materialas are measured continuously varying from low to high environmental temperature and the material characteristics acan be accurately and easily evaluated.
RHEOVIBRON, as a representative automatic measuring system of dynamic viscoelasticity, is being used in various contires for many years in the fields of research and development for dynamic characteristics and quality inspection control. |

| Characteristics |
| Viscoelasticity characteristics of duplex structure material as coat material can be measured. |
| With application of various jigs, wider range of viscoelaticity ratio can be measured. |
| Accroding to the change of characteristics of the testpiece, automatic switching function for testing control works from constant amplitude control to constant load control. |
| Frequency characteristics range is wide as 0.01 to 100Hz. |
| Frequency measuring points are many as 137. |
| Vibration amplitude is available in the ranges of ±4~±160µm(01GP), ±8~±250µm(25GP) and±500µm(*25GP as optional) |
| Plenty optional function such as various testing jigs, piezoelectricity measurement, stress/ relaxation measurement and creep testing |
| Software for application of optional items such as mater curve, activated energy, Tg (tanδ) automatic/manual detection and Tg (E') manual detection. |
| Set-up for the most suitable testing condition by pretension function is possible. |

Applicable to research/ development and quality inspection for temperature-dependence (-150 degree Celsius ~ + 400 degree Celsius), cycle dependence (0.01 ~ 110Hz), amplitude-dependence of heat-resisting material and sound absorbing material.
DDV-GP series is a dynamic viscoelasticity measuring system with non-resonance forced vibration method and consists of measurement operation block, high/low constant temperature chamber, main unit, power unit (for 25GP), data processing device and various testing jigs (optional items).
Applying the most suitable tension to one end of a loaded testpiece with automatic tension function, and adding the dynamic displacement like sin wave vibaration Ao sin Ωt (sinusoidal stress) as a forced power, detects dynamic load appeared on the other end of the testpiece. By processing tosignal and computing the dynamic strain anddynamic stress, measures complex modulus of elasticity E*, dynamic modulus of elasticy E', loss modulus of elasticity E'' and loss tangent tanδas dynamic mechanical characteristics of the testpiece. Furthe, changing condition under atmosphere environmental condition, tests and outputs the data to the CRT display at the same tiem. |
