Automobile chassis rear-overhang part assembly simulated detection tool and detection analysis method

The invention relates to an automobile chassis rear-overhang part assembly simulated detection tool and detection analysis method. According to the detection tool, the tool is assembled on a detectionplatform and detection equipment is used to measure the tolerance of the tool after assembly, the tool is used to detect parameters including function, size and manufacturing deviation of automobilechassis rear-overhang parts and function and size of a general assembly, whether a chassis rear-overhang unit is qualified is detected, a deviation accumulated phenomenon in the chassis rear-overhangassembling process is simulated, influence of a manufacturing deviation accumulation effect of parts in the assembling process on the function and size of the assembled general rear-overhang assemblyis analyzed and compared to obtain contribution of the manufacturing deviation of each part to the final assembling error, and thus, guidance is provided for tolerance optimization of the parts, the rear-overhang assembling prec
