The invention relates to an intelligent adjustable human model, comprising a physical characteristic input module, a model trunk structure, a plurality of neck circumference adjusting plates, a neck circumference adjusting mechanism, a plurality of chest circumference adjusting plates, a chest circumference adjusting mechanism, a plurality of waist circumference adjusting plates, a waist circumference adjusting mechanism, a plurality of hip circumference adjusting plates and a hip circumference adjusting mechanism. The circumference adjusting mechanisms are arranged between each adjusting plate and the trunk structure, and control the relative movement of the adjusting plates and the trunk structure to realize accurate adjustment of physical circumference parameters. The human model has the advantages of convenience in operation, economical efficiency, practicability and good adjusting effect, and can realize independent adjustment of multiple physical parameters of neck circumference, chest circumference, waist circumference and hip circumference.
