GB/T 35218-2017 in English

Interpretation of the Standard for Tractor Reliability Bench Test Methods

1. Background and Significance of Standard Formulation

GB/T 35218-2017 "Tractor Reliability Bench Test Methods" is to standardize the reliability test of agricultural tractors under different working conditions to ensure that their performance and durability meet the requirements of national standards. The formulation of this standard is based on many years of technical accumulation and practical experience in the field of agricultural machinery, combined with internationally advanced test methods, and aims to improve the quality level of domestic tractors and promote technological progress in the industry.

3. Key technical parameters and terminology explanation

4. Implementation suggestions and precautions

1. Test equipment selection: Ensure that the instruments and equipment used (such as power output shaft power test bench, hydraulic suspension test bench) meet the requirements of GB/T 3871 series standards.
2. Test condition control: Strictly follow the provisions of GB/T 3871.1 to ensure that the test environment (such as temperature, humidity) and lubricant selection meet the requirements of JB/T 7282.
3. Data recording and analysis: It is recommended to use professional software to monitor and record the test data in real time for subsequent reliability evaluation and improvement.
4. Fault handling: For faults that occur during the test, they should be recorded in detail and classified (fatal, serious, general, and mild) to ensure that the hazard coefficient (such as 30.0 for serious faults) and the time coefficient E_i are calculated accurately.

5. Conclusion and Prospect

The implementation of GB/T 35218—2017 will help improve the overall technical level of the tractor industry and provide a solid technical guarantee for the development of agricultural mechanization. In the future, as agricultural machinery develops towards intelligence and efficiency, reliability test standards will continue to be optimized to meet the needs of new technologies and new working conditions.
