Abstract： Viscosity，as a fundamental property offluids，holds significant technical value across various fields， including petroleum， chemical enginering， mechanical systems，and nuclear power. In nuclear applications， specifically，coolant fluids like water orother liquids exhibit viscosity changes influenced by temperature and pressure，impacting reactor cooling eficiency. Viscosity sensors are thus essential for real-time monitoring to ensure coolant viscosity remains within an optimal range， maintaining efective reactor cooling. This study developsa novel viscosity measurement system based on four-degre-of-freedom torsional vibration techniques， focused on structural optimization and parameter control. Utilizing the mechanical impedance method， we theoretically analyze the dynamic response of the system in relation to fluid viscosity，establishing a comprehensive theoretical model.The derived analytical solution for the four-degree-of-freedom parameter equations offers a new approach to viscosity measurement and shows promising potential for designing online monitoring devices with extensive practical applications.
