Spring puncture point positioning method and device based on Macpherson suspension and storage medium

The invention discloses a spring puncture point positioning method and device based on a Macpherson suspension and a storage medium, the spring puncture point positioning method comprises the steps of: establishing a first model used for calculating and outputting the lateral force of a shock absorber, wherein the first model comprises the shock absorber, and the shock absorber comprises a spring; establishing a Macpherson suspension simulation model based on the first model; based on the condition that the first mounting point of the spring is located in different coordinates, performing parallel wheel jump analysis and roll motion analysis by utilizing the Macpherson suspension simulation model, and outputting lateral force curves at an oil seal and a piston of the shock absorber; determining a target first mounting point of the spring according to the output lateral force curves at the oil seal and the piston of the shock absorber; and determining a target second mounting point of the spring according to t
