With the rapid development of industrial technology, the complexity and precision of mechanical equipment are constantly improving, and the requirements for testing mechanical properties are becoming increasingly stringent. Existing test benches usually have a single function and can only perform a specific type of test, such as vibration testing, dynamic balance testing or strength testing, and cannot achieve comprehensive testing of multiple mechanical properties. This single-function test bench not only increases the company's equipment procurement costs, but also reduces detection efficiency, making it difficult to meet the needs of multi-dimensional mechanical properties testing in modern industrial production.
