The test benches currently used in the test have a high degree of electromechanical integration, powerful functions, complex structures, and are also expensive. With the continuous enrichment of the product spectrum, product testing requirements are also changing dynamically. For some urgent test requirements such as CPCA, clutch TB test, etc. that require front-drive functions, it is necessary to temporarily mobilize test resources to quickly build a bench to meet the test requirements.
