Automobiles are power-driven, non-rail-borne vehicles with 4 or more than 4 wheels, primarily used for: carrying personnel and cargo; a vehicle for towing carrying personnel and cargo.

In the use process of the automobile, various parts are used, wherein the parts are all units forming the whole automobile and serve as a product of the automobile, and the parts are various, wherein the front auxiliary frame is one of the categories of the parts.

The front subframe can be regarded as a framework of the front axle and the rear axle and is a component of the front axle and the rear axle. The subframe is not a complete frame, but merely a bracket that supports the front and rear axles and the suspension, through which the axles and suspension are then connected to the "main frame", conventionally referred to as the "subframe". The sub-frame has the functions of isolating vibration and noise and reducing direct entering of the sub-frame into a carriage, so that the sub-frame is mostly arranged on luxury cars and off-road vehicles, and the sub-frame is also arranged on an engine of some vehicles. Conventional vehicle bodies without sub-frames have suspensions that are directly connected to the body steel panels. Thus, the suspension rocker mechanisms of both the front and rear axles are discrete components and not an assembly.

The key parts of the connection between the vehicle body and the chassis need to bear certain load when the vehicle runs, so that in order to meet the running requirement of the vehicle, the local dynamic stiffness of the parts needs to meet certain target value requirements, and the response of the installation point of the chassis part under the excitation of steady-state vibration needs to be acquired on the basis of free mode and static stiffness analysis. In the structural design of the chassis, some key points, including an engine suspension point, a shock absorber mounting point, a trailing arm mounting point, an auxiliary frame mounting point and the like, are main sources for transmitting vibration to a vehicle body, and have important influence on vibration and fatigue failure of the vehicle body, so that the dynamic stiffness requirements of the points need to be ensured.

At present, in the use of a front subframe, the analysis of the dynamic stiffness of a mounting point is mostly the rigid connection constraint of a vehicle body point, and when the dynamic stiffness decomposed by the chassis is added to the vehicle body point, the analyzed result of the mounting point is greatly reduced compared with the rigid connection result of the vehicle body point, so that the target requirement is not met, and the weight and the occupied space are increased when an external part is additionally arranged.

SUMMERY OF THE UTILITY MODEL
