Seat belt tensile testing machine technical parameters

Seat Belt Tensile Testing Machine: Application and Technical Description 1. Scope of Application The QX-W500 Microcomputer-Controlled Electronic Universal Testing Machine is a versatile testing equipment designed to evaluate the mechanical properties of various materials, including metals, non-metals, and polymer materials. It can perform a wide range of tests such as tension, peeling, compression, bending, shearing, breaking, and piercing. The machine also supports fatigue testing. It can be configured according to international standards like GB, ISO, ASTM, JIS, and EN, depending on the customer's specific product requirements. The system automatically collects key parameters such as maximum test force, breaking force, yield strength, tensile strength, compressive strength, flexural strength, elastic modulus, elongation rate, constant elongation stress, and constant stress elongation. 2. Technical Description This microcomputer-controlled electronic universal testing machine utilizes advanced control technology. It employs an imported AC digital controller to drive a servo motor via a synchronous belt, ensuring precise movement of the high-precision ball screw test bench. The test bench can operate at speeds ranging from 0.001 mm/min to 500 mm/min. The system uses a high-precision tension and pressure sensor imported from the United States, offering an accuracy of 0.02%. The overall system achieves a precision level of 0.5%, with an effective force range from 0.2% to 100% of the maximum force value. The accuracy of force measurement is within ±0.5% of the indicated value, displacement accuracy is within ±0.5%, and deformation measurement accuracy is also within ±0.5%. 3.

Software Reliability The reliability of the computer-controlled testing machine lies in both hardware and software components. To ensure stability, we use highly integrated and technologically advanced components, reducing the number of parts and solder joints. Our software has more than three times the code volume of similar systems, but its modular structure allows for efficient development and maintenance. The software separates the main program from the calculation and report modules, enabling independent updates and debugging. This approach ensures that the main program remains stable while the calculation and reporting functions can be easily modified. The use of MS-ACCESS database simplifies data processing, and Crystal Reporter is used for visually appealing and reliable report generation. Http://news.chinawj.com.cn Submission:
