The present disclosure relates to a method, apparatus, electronic device and storage medium for interaction. The method includes: presenting a target interface including an information flow area and an information input area; in a case that input information to be released is detected in the information input area and the input information satisfies a preset condition, presenting query keyword prompt information; and in response to a triggering operation on the query keyword prompt information, presenting query result content. This is substantially meant that the input information is automatically identified, during the editing of the input information by a user, the input information is converted into the query keyword prompt information for presentation, and in a case that the query keyword prompt information is triggered by the user, the query result content is directly presented, so as to assist the user in quickly obtaining the query result thereof.

The invention disclosed a friction coefficient measuring device under the condition of material periodic deformation. The measuring device is mainly composed of a torque sensor, a sleeve system, an upper sample, a lower sample, a flexible fixture, an air bearing, a clamping system, a tension-compression sensor, a support rod, and a support table. A working module of a friction-wear testing machine is connected with the torque sensor and then connected with the sleeve system to fix the upper sample. A rotating module of the friction-wear testing machine is used for connecting the flexible fixture to fix the lower sample. The tension-compression sensor can accurately measure the radial force between the upper sample and the lower sample. The torque sensor can measure the load torque values of the upper sample and lower sample during testing. According to the curve of the load torque value and radial load value change between the upper sample and lower sample, the friction coefficient between the flexible bearing and flexible gear is obtained.

The present disclosure discloses a detecting device and method for acoustic emission on high-frequency motion rubbing pair surface. A linear reciprocating slide system with high efficiency and high conductivity is designed based on the method. Reciprocating linear slide system is the main structure of the detection device which is is composed of probe plate, tight clips, vacuum cover, slip wire and insulation box. The reciprocating slide solves the problem of data distortion caused by high frequency jitter when connecting ordinary data lines, and can realize stable and reliable connection between high frequency reciprocating rubbing experiment and acoustic emission detection equipment. The acoustic emission probe on the surface of rubbing pair connects with the preamplifier by linear reciprocating slide. Real-time monitoring of acoustic emission equipment is realized to obtain the state change of rubbing pair surface during high-frequency reciprocating rubbing, and further analyze the wear mechanism of different rubbing pair.
