Automobile Industry

BYD is an influential automobile manufacturer in China that is committed to providing consumers with high-quality and high-performance automotive products. In order to ensure product quality and reliability, the company has introduced a series of advanced reliability testing equipment. Here are the specific data and applications:

1. Engine block detection: Use ultrasonic flaw detection equipment to detect tiny cracks and defects inside the block. The test data showed that in the past 1,000 cylinder block samples, 50 samples with defects were successfully detected, and the accuracy of defect detection reached 98%.- Using the cylinder body pressure test equipment under different conditions, the data shows that the newly designed cylinder can withstand up to 200 mpa, and the pressure sealing remains above 99.5% after 1000 hours of continuous operation.
2. Transmission gear detection: The surface hardness of the gear is measured using hardness testing equipment. Data statistics show that the average hardness of the gear surface reaches HRC60, and the hardness deviation is within ± 2 HRC, which ensures the wear resistance and service life of the gear. Using the fatigue testing machine, after 1 million cycles, only 2% of the gears had tiny fatigue cracks, well below the industry average.
3. Brake system detection: With the help of the brake disc dynamic balance detection equipment, it is found that more than 95% of the brake disc dynamic balance deviation is within 5 g · mm, effectively reducing the jitter and noise during braking. - Measure the friction coefficient of brake pads at different temperatures. The data show that the friction coefficient is stable between 0.35 and 0.45 in the temperature range from 200 °C to 600 °C, ensuring the stability and reliability of braking.
4. Electronic parts testing: Test the automotive electronic control unit (ECU) using EMC testing equipment. The results show that in the complex electromagnetic environment, the bit error rate of the ECU is lower than 0.1%, and the anti-interference ability reaches the advanced level of the industry. - For each circuit board, the detection data shows that the defect detection rate of the circuit board is as high as 99%, which greatly reduces the failure rate of the electronic system.

Through the application of this reliability testing equipment and accurate data support, BYD has significantly improved the quality and reliability of auto parts, reduced the after-sales maintenance rate, and enhanced the brand image and market competitiveness. For example, within half a year after the launch of the new model, the customer complaint rate has decreased by 40% compared with the previous generation model, and market satisfaction has increased by 30%, which has brought significant economic benefits and a good reputation to the company. The above cases fully demonstrate the important role and remarkable effect of reliability testing equipment in the automotive field.
