Hongqi Motors develops China's first fully automated suspension K&C simulation tool, achieving efficiency improvement of 500%

News from this site on November 24, according to official news from FAW Hongqi, the Chassis Development Department of the New Energy Development Institute of Hongqi R&D Institute ushered in new results. developed the first domestic suspension K&C fully automated simulation tool - " K&C Auto” claims to increase simulation and development efficiency by 500%.

Notes from this site: Suspension K&C characteristics refer to suspension kinematic characteristics (Kinematic) and elastic kinematic characteristics (Compliance) , affected by the characteristics of suspension hard points and elastic parts, plays a decisive role in the vehicle's handling, stability and ride comfort. In the development process of dynamic performance, the design and optimization of suspension K&C characteristics are crucial, involving hundreds or even thousands of rounds of K&C characteristics simulation calculations.

According to reports, in order to solve the pain points of long-term and error-prone K&C manual simulation calculations, the dynamics development team independently developed the K&C Auto automated simulation tool, realizing K&C characteristic simulation and processing with one click, fundamentally solve the pain points of K&C performance development.

The K&C Auto tool includes three functional modules: K&C simulation, result processing and report output, which can support the entire K&C performance development process:

Simplify operations and improve efficiency

In the automatic simulation module, we can realize the simulation of more than 10 typical K&C working conditions. By using load condition simulation setup program mapping technology, we are able to ensure standardization of K&C characteristic simulations. At the same time, we also combined the developed Matlab and ADAMS tool chains and used batch processing technology to achieve one-click simulation of K&C characteristics in all working conditions

Fast analysis and efficient processing

By optimizing the program architecture and algorithm, the data parsing path is improved in the automatic post-processing module, which solves the problem of slow parsing speed of res simulation result files and increases the parsing speed of res files by 80%. At the same time, combined with the development of methods and programs for processing more than 70 K&C key performance indicators, the simulation post-processing time has been shortened from 4 hours to 1 minute, greatly improving the efficiency of data processing

Intelligent analysis, Ready-to-use

In the K&C Auto report automatic output module, based on the K&C benchmarking database and combined with big data analysis, the K&C target automatic setting function is developed, which can automatically position based on vehicle basic information and performance By setting K&C goals and combining with the automatic report output function, K&C simulation report files in multiple formats can be generated, enabling ready-to-use imitation and real-time output of reports, further reducing performance development workload and improving development efficiency.
