Abstract

The present invention relates to the technical field of automobile suspension systems, in particular to a layout check calculation method based on automobile suspension systems, which is used to accurately judge whether the positional relationship between the torque axis and the elastic axis is reasonable, including: obtaining the left suspension elasticity The position of the elastic center of the center and the right suspension to determine the elastic axis; the torque axis is determined according to the position of the center of mass of the powertrain and another point, and the position of this point is based on a given value S, the center of mass of the powertrain and the rotation of the powertrain The inertia and product of inertia are calculated; at the same time, the elastic axis and the torque axis are unified into the vehicle coordinate system; and then it is judged whether the angle and distance between the elastic axis and the torque axis are reasonable. The invention can accurately judge the rationality of the position of the automobile suspension system, avoid adjustment after the automobile suspension system has not been calculated and arranged, save manpower and material resources, and accelerate the development progress of the complete vehicle.

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 ...
