Method and device for optimizing output force of attachment point of automobile chassis

The invention relates to a method and a device for optimizing the output force of an automobile chassis attachment point. The method comprises the steps of obtaining a first super unit of an automobile; the first super-unit is a super-unit model established according to the first vehicle body mass, the first vehicle body mass center coordinate and the first rotational inertia; obtaining the maximum force envelope value of each chassis attachment point of the automobile at different preset probability frequencies according to the first super unit, and taking the maximum force envelope value as an undetermined envelope value; the set of the to-be-determined envelope values at different preset probability frequencies is a to-be-determined envelope value set; obtaining a standard envelope value according to a preset target path noise value; if all the to-be-determined envelope values in the to-be-determined envelope value set are smaller than the standard envelope value, the to-be-determined envelope value set is
