Problems solved by technology
However, the system composed of this cannot know the control performance index of electrorheology
The reason is that the response time of the pressure gauge is long, the relationship between the pressure difference and the voltage before and after the throttle valve cannot be described, and the synchronization of various parameters or the description of the change of the interval with time cannot be realized.
The current market data acquisition card can not meet the requirements of the device signal acquisition

The invention provides a device for detecting a performance index of an electrorheological damper. The device comprises a host computer, a DC high voltage generator, a multifunctional data acquisitionmodule, a surge protector and a mechanical device test platform. The surge protector is externally connected with a voltage source to transmit a 24V DC voltage provided by the voltage source to the DC high voltage generator. The DC high voltage generator generates a 0-20 kV DC high voltage output according to the DC 24V voltage transmitted from the surge protector under the control of the host computer. Under the control of the host computer, the multifunctional data acquisition module performs control and data acquisition on the mechanical device test platform. The mechanical device test platform performs an electrorheological damping performance test under the control of the multifunctional data acquisition module. The device of the invention realizes that different voltage yield stress, response time, shear stress, current variable efficiency and response time of the electrorheology are equal to actual application performance indexes.
Description
technical field [0001] The invention relates to the technical field of shock absorber detection, in particular to a device for detecting control performance indexes applied to electrorheological shock absorbers. Background technique [0002] Electrorheological fluid is a type of colloid in which dielectric particles are suspended in a non-conductive continuous phase. When an electric field of a certain strength is applied to the electrorheological fluid, its rheological properties will change immediately, from liquid to solid state. When the electric field is withdrawn, it immediately returns to the original liquid. The electrorheological fluid has the following characteristics in the electric field: (1) Rapid conversion between liquid and solid-like, that is, the apparent viscosity can change greatly at static or low shear rates, and it has the shear resistance of solid properties. (2) The conversion between liquid and solid is reversible; (3) This conversion is controllab...
