Definitions
- the invention relates to a Rotationsrheometer for measuring rheological characteristics of a material sample, with a motor whose torque is directly or indirectly detectable and which drives a rotatable shaft, whose movement and position can be detected, with a shaft held on the rotor and a stator, said a measuring space for receiving the material sample is formed between the rotor and the stator, and with a controller which regulates the motor on the basis of an internal control method or internal control parameters, whereby the internal control method or the internal control parameters of the controller can be changed ,
- the invention has for its object to provide a rotational rheometer of the type mentioned, with their material properties can be detected with high accuracy for different material samples.
- a corresponding method for determining material properties of a material sample by means of a corresponding rotational rheometer is to be created.
- these experimental data are used in a preliminary test, i. before the actual measurement of the material sample, to determine the rheological characteristics with respect to the properties of the material sample.
- This preliminary test must be designed so that it does not affect the material sample and does not change its material properties.
- the optimum control parameters and the associated control method are determined for the current material sample, whereupon the controller is configured with these control parameters and then the actual attempt to determine the material characteristics is carried out.
