s2: when testing the heat dissipation effect of a plurality of heat conduction silica gel sheets at different temperatures, controlling the heating blocks in a plurality of heat dissipation assemblies to work, stopping working of the heating blocks after the temperature sensors corresponding to the heating blocks respectively reach the specified different temperatures, sequentially placing the heat conduction silica gel sheets to be tested on the upper part of a rotary supporting table in a heat dissipation test assembly, and then testing the heat dissipation performance of the heat conduction silica gel sheets of different types according to the data change transmitted by the temperature sensors;
s3: when the tensile property of the heat-conducting silica gel sheet is tested, two ends of the heat-conducting silica gel sheet are respectively and fixedly clamped between an L-shaped upper clamping plate and a lifting lower clamping plate at two longitudinal ends of a supporting bottom plate through the cooperation of a second lifting device and a third lifting device, the heat-conducting silica gel sheet is stretched under the driving of a telescopic device, and the tensile property of the heat-conducting silica gel sheet can be judged by monitoring the returned data through a pressure sensor and a CCD (charge coupled device) camera detection probe;
S4: when testing heat conduction silica gel piece damping performance, control tensile test subassembly decline, under the cooperation of lift mounting panel, lift support column and lift bracing piece, through the electro-magnet with cylindricality test piece inhale and rise to appointed height, under the cooperation of first moving mechanism, remove the guide cylinder in the shock attenuation test subassembly to the top of heat dissipation test subassembly, control rotating electrical machines drive the heat dissipation subassembly adjustment position in the rotatory backup pad, make rotatory testboard be located under the guide cylinder, can control the electro-magnet outage afterwards, cylindricality test piece free fall is in heat conduction silica gel piece upper portion, monitor and observe cylindricality test piece rebound height and data such as number of times through displacement sensor, rectangle fretwork observation window and scale marking, can test out the shock attenuation effect of heat conduction silica gel piece, and when testing the shock attenuation effect of heat conduction silica gel piece in the heat dissipation process, only need control the work of heating block in the corresponding heat dissipation test subassembly, make corresponding temperature sensor after rising to appointed temperature, control electro-magnet outage, cylindricality test piece free fall is monitored and cylindricality test piece rebound height and number of times etc. data such as heat conduction silica gel piece.
