Problems solved by technology
[0003] However, during the measurement process, there is interference from the unbalanced quantity in the non-measured direction, which makes the measured data inaccurate. Therefore, there is a lack of a measuring device that can separate the unbalanced quantity of the static couple and has high detection accuracy in the prior art.

The invention discloses a high-separation ratio static-couple separation floating platform type measuring device. The device comprises a measuring platform bottom plate, two groups of vibration sensorassemblies, a floating platform and two groups of spring rod reed assemblies. The floating platform is installed on the measuring platform bottom plate in a floating mode through the two groups of spring rod reed assemblies. The two groups of vibration sensor assemblies are perpendicularly and orthogonally fixed on the measuring platform bottom plate and are connected to the bottom of the floating platform. A workpiece is mounted on the top surface of the floating platform, the workpiece is electrified to rotate to generate vibration, and the vibration magnitude is transmitted to sensor measuring rods of the two groups of vibration sensor assemblies through the floating platform, so that the static unbalance and couple unbalance of the workpiece are monitored. The vibration sensor assemblies involved in the invention are in vertical orthogonal design, the separation of static couple balance is effectively realized, the degree of freedom in a non-detection direction can be limited, theinterference is greatly reduced, and the measurement precision is improved.
Description
technical field [0001] The invention relates to a balance quantity measuring device, in particular to a high separation ratio static couple separation floating platform measuring device. Background technique [0002] For automotive cooling fans and similar ultra-thin rotors (when the ratio of rotor diameter D to thickness H is 8 to 16 times), the residual unbalance seriously affects the vibration and noise of the system, as well as the stability of operation. Chinese patent authorization number CN201909701U, invention name "High Separation Ratio Static Couple Dynamic Balance Measuring Device", discloses a dynamic balance detection device that can simultaneously detect static unbalanced force and coupled unbalanced force for ultra-thin rotors, and specifically describes the vibration The outer periphery of the disk is provided with a corresponding fixed seat, and the vibrating disk is respectively provided with a flat torsion mechanism, a bending mechanism, a horizontal tensi...
