Abstract

The invention relates to the technical field of automobile suspension systems, in particular to a layout verifying calculation method based on the automobile suspension system. The layout verifying calculation method is used for accurately judging whether the position relation between a torque shaft and an elastic shaft is reasonable or not and includes steps of acquiring the positions of the elastic centers of a left suspension and a right suspension so as to determine the elastic shaft; determining the torque shaft according to the power assembly centroid and the position of another point which is calculated according to a given value S, the power assembly centroid and rotation inertia and inertia product of the power assembly; unifying the elastic shaft and the torque shaft to a coordinate system of the integral automobile; judging whether the included angle and the distance between the elastic shaft and the torque shaft are reasonable or not. By the layout verifying calculation method, reasonableness of the position of the automobile suspension system can be accurately judged, adjustment after the automobile suspension system is arranged without calculation is avoided, labor and material source are saved, and development speed of the integral automobiles is accelerated.

Description

technical field [0001] The present invention relates to an automobile engine mount system, hereinafter referred to as a mount system or an automobile mount system, and in particular to a layout check calculation method based on an automobile mount system, which is used to accurately determine the position between the torque axis and the elastic axis Whether the relationship is reasonable. Background technique [0002] With the continuous development of the automobile industry, people's requirements for driving comfort are also increasing. Therefore, the suspension system plays an increasingly important role. In the design of the suspension system, position layout and position checking are a It is a very important design process, focusing on the positional relationship between the torque axis and the elastic axis. The closer the torque axis is to the elastic axis, the better the vibration isolation effect of the suspension system and the higher the decoupling rate, the more ...
