The invention provides a microgravity test system for simulating an on-orbit assembly environment on the ground. A spring force measuring assembly, a pulley hanging assembly, a linear motion module and transverse and longitudinal guide rails are fixedly mounted on an unloading truss. One end of an assembled object is fixed on the simulation wall, and a lifting bolt and a turn buckle are arranged above the other end of the assembled object and are connected with the spring force measurement assembly through a lifting rope for compensating derived force generated by the assembled object in the assembling process; the lower ends of the pulley hanging assemblies are fixedly connected with an assembled object 1 through lifting ropes, turn buckles and lifting bolts, the upper end of each pulley hanging assembly is connected with a longitudinal guide rail on an unloading truss, and every two pulley hanging assemblies are arranged in parallel. The linear motion module is installed on the unloading truss through a connecting plate, a fixed pulley is installed at the lower end of the linear motion module, the linear motion module is fixedly connected with the assembled object 2 through a lifting rope, a turn buckle and a lifting bolt, when the clamping tool drives the assembled object 2 to move, a gear motor on the linear motion module rotates to drive the fixed pulley to actively follow, and the unloading efficiency is further improved. The microgravity test system for simulating the on-orbit assembly environment on the ground is suitable for simulating an on-orbit assembly test on the ground, is particularly suitable for an assembly task with a plurality of assembly objects, is easy and convenient to install, high in stability and good in universality, can be used for simulating the on-orbit assembly environment on the ground, and is suitable for popularization and application. And the influence of the ground gravity on the test is eliminated to the greatest extent.
