Accelerated life test method and system for marine medium-temperature rubber flexible connecting pipe

The invention provides an accelerated life test method and system for a marine medium-temperature rubber flexible connecting pipe, and the method comprises the steps: carrying out the thermogravimetric analysis of the medium-temperature rubber flexible connecting pipe, so as to calculate an acceleration factor of an acceleration test temperature relative to a normal use temperature; carrying out a service life acceleration test on the medium-temperature rubber flexible connecting pipe at the acceleration test temperature, and carrying out aging characteristic parameter detection in the test process to obtain detection data; performing linear fitting by using the detection data so as to determine time corresponding to a failure threshold value of the aging characteristic parameter; multiplying the time corresponding to the failure threshold by an acceleration factor to obtain the service time at the normal use temperature; and calculating the non-service time at the normal use temperature based on a preset rat
