Problems solved by technology

However, this method has the following problems: First, the reserved value of the clearance between the components of the mounting system and the surrounding area is judged based on empirical values, and there may be over-design or insufficient design; Whether there is a risk of collision inside the component; third, this method needs to continuously optimize and adjust the suspension structure according to the CAE analysis results, the workload is large, the processing cycle is long, and the efficiency is low

Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings.

[0035] In order to facilitate the detailed description of the method of generating the motion envelope of the suspension system, the following is mainly based on the figure 2 The 30th working condition (hereinafter referred to as working condition 30) in the example is used to describe the envelope generation.

[0036] like figure 1 A method for generating a motion envelope of a suspension system is shown, including the following steps:

[0037] S1. Collect the digital and analog parameters of the powertrain and mounting system to provide a basis for subsequent simulation analysis. The digital and analog parameters of the powertrain and mounting system include but are not limited to structural parameters, material parameters and motion parameters. The digital-analog parameters of the powertrain and the mounting system can be obtained through measurement and testing....

Abstract

The invention relates to a method for generating a motion envelope of a suspension system. The method comprises the following steps: collecting digital-analog parameters of a power assembly and the suspension system; the suspension system parts are divided into pull rod type suspension system parts and fixedly-connected suspension system parts fixedly connected with a power assembly, and motion envelope generation is conducted on the pull rod type suspension system parts and the fixedly-connected suspension system parts; and obtaining the motion envelope of the suspension system according to the motion envelope of each fixedly connected suspension system part and the motion envelope of each pull rod type suspension system part. According to the invention, the motion envelope of the suspension system can be generated.

Description

technical field [0001] The invention relates to a suspension system, in particular to a method for generating a motion envelope of a suspension system. Background technique [0002] Mounting system is a very important part of the car, which is responsible for fixing the powertrain, damping the vibration of the powertrain, and limiting the displacement of the powertrain. The performance of the mounting system is strongly related to the NVH performance of the vehicle. However, in fact, the design of the components of the suspension system is affected by the powertrain, body, chassis and other related components. The layout position and design space of the suspension system are greatly limited, which squeezes the design space of the vibration isolation rubber, resulting in components and parts. In the design stage, it is impossible to identify whether the design space reserved for the structure of the components of the suspension system can meet the necessary performance requir...
