Driving seat design method

The invention discloses a driving seat design method and belongs to the technical field of vehicle driver seats. The problem that existing seat design is blind and accordingly seats are designed and modified many times is solved. The method includes the steps that according to a sponge material constitutive model, a sponge deformation model is constructed through a non-linear finite element; ideal pressure distribution data is obtained through sitting posture pressure distribution measurement and experiment statistics, and an ideal pressure distribution model is built; sample points used for seat design are extracted through human body data statistics and analysis of target population, according to given driving cab distribution parameters and the sample points, a comfortable sitting posture driver body is determined by means of a posture prediction model, and a sitting posture human body finite element model is constructed; the ideal pressure distribution model is mapped to the surface of the sitting posture
