Automobile reliability test, automobile reliability testing mechanism.
Where is the car reliability test?Where can I do the reliability test?Where is the car reliability testing agency?Is the purpose of the reliability test, found in the product design, material and process all kinds of defects, through the analysis and improvement, make the product reliability growth step by step, finally to the expected level of reliability;Provide information for improving the readiness of products, improving the success rate of tasks and reducing maintenance costs;Verify compliance with specified reliability requirements.The following is a guide to the reliability test of road vehicles:
With the development of our domestic economy and manufacturing specialization, differentiation, the impact of opening to the outside world to the Chinese market, accelerate the upgrading of the Chinese car industry and the engineering innovation plays the role of China's automobile industry to synchronization and the world auto industry development and even to reach the advanced level, in addition to technology research and development innovation, the reliability of the automobile road test field study is one of the important aspects.This paper mainly discusses the road test in automobile reliability test.The purpose is to give full play to the role of automobile road reliability test in improving automobile performance.
Purpose and classification of reliability test of automobile road.
1. Purpose of automobile reliability test.
The purpose of automobile reliability test is to assess the automobile and its parts.First, through the test data, the product reliability, average life, and loss of efficiency produce reliability index.The strength, reliability, function and service life of automobile products are assessed on the standard of production.Secondly, the analysis of automobile failure mechanism.For test road reliability test, products in the design, manufacturing, etc, are easy to cause motor failure, directly exposed problems and weak links, for this, should be timely find the failure reason, continue to improve production, makes to improve reliability.Finally, explore the direction of automobile development, innovate design ideas, and accumulate experience for new product development.
2. Classification of vehicle road reliability test.
The main classification criteria for reliability test of automobile road are test site, test condition, test object and test failure.According to the experimental site classification, mainly includes: test field test, field test and laboratory test.At different stages of production, the tester should make different choices according to different requirements.This paper mainly talks about the reliability test of road test.There are many types of road test in automobile test field: straight lane, curved lane, test square, high-speed ring road, special environment, special ring, etc.This paper mainly analyzes three kinds of high-speed ring road test, field road test and strengthening road test.
Road reliability test of vehicle test field.
1. High-speed ring road test.
The full length of the high speed loop is 4000m, the ring road is oval in shape and the radius of curvature is 165m.The speed design is 104-140km/h, 66--104km/h and 44-66km/h in the test field road test.The full circular driveway is divided into three lanes.The highest speed is 160km/h.Mainly used cement concrete paving road, the equal grade is A grade, the slope is 42.3.The specific test procedure is that the tire pressure should be measured before the vehicle is driven into the high-speed ring road, and the actual technical requirements are met.After entering the ring road, use the most advanced driving test in clockwise direction.The average speed is not less than 90 percent of the maximum speed during the test.The test time cannot be less than an hour and a half., for example, in the process of using high speed ring test, in order to simulate the car under various road conditions of the actual situation, and built the dirt road, bump road, ShaShi Road content of intensifying test, the test of the car in a short time exposed problems, for to improve the performance of the car, on the performance of the car in the condition of high-speed form and test the reliability of the parts.
2. Road test in the field.
There are two main roads in the field, the first and the second.The road surface of the first floor is paved with sand and gravel, and the level of pavement level is level 2.The maximum slope is 20%, the continuous slope is 1400 meters, and the average slope is 8%.The second hill has a snake-like shape.There are mainly ups and downs, slope paths and ridge paths.The pavement is paved with sand and gravel, and the level of pavement level is level 2.Due to the frequent braking, the main road is to check the operation of the brake system.In the reliability test of the roadway, the test of the vehicle's verified braking system is carried out.Check whether the vehicle is weak, verify brake friction disc and brake drum in wear-resistant performance.Whether the vehicle exists to verify the anti - thermal deterioration of the brake.At the same time, the strength of other parts of the car can meet the requirement of sex.
Some problems need to be paid attention to in order to reduce the problems in the test.The first thing to note is safety.The experiment should be carried out smoothly on the basis of ensuring safety.When conducting road tests, it is necessary to drive at a higher speed, at this time, there is no limit on the gradient.When driving down the slope, it should be used in principle to run at a speed higher than the above grade, use the driving brake, or be equipped with an exhaust brake to assist the brake to carry out the test.The car needs to use normal exhaust auxiliary brake!During the test of the test vehicle, the braking system of the vehicle braking system is set up to disassemble and confirm the cycle, which is 1000km/ time.
3. Improved road test.
The reliability test of the reinforced road in the automobile testing field is mainly the durability test of the automobile.In the durability test, the stress requirements of the automobile are higher, and the reliability test is "concentrated".The strengthening of the road experiment with various targets, main goals: first, under normal conditions of use, for car use is rare in normal, or almost no occurrence of fault test, showing in extreme cases, the performance of the car.In the process of testing, the authenticity of the fault should be reflected.Second, the general use of the fault, mainly using the long driving distance, testing the car in endurance.The durability of the car is exposed [3].Finally, in the experiment of strengthening reliability, it is necessary to improve the efficiency of the experiment and shorten the period.In the actual experiment, the reinforcement test of the vehicle is different to the meaning.Because of the complexity of the test road, in order to reach the established test target, there are various limit requirements for vehicle type and speed.In this process, we should pay attention to the safety of vehicles.When driving the vehicle to carry out the reliability test of the road strengthening road, it is necessary to carry out the test according to the specified speed and gear.For every 800km of test vehicle reinforcement road, it is necessary to disassemble the brake system in time to debug the braking condition of the vehicle.
United testing reminds us that the test field road test is an indispensable part in the reliability evaluation of automobile products.In the use of proving ground road test method, the implementation of the analysis of the failure samples, looking for the weak link, under the corresponding countermeasure, to achieve the purpose of automotive product reliability gradually increase.After the statistics, analysis and processing of the data obtained in the test field road test, the performance of the automobile can be greatly improved based on the research and design of reliability data.For more details on the reliability test, please contact us or send the product and related information to our email address: hofferlau@uni-lab.hk, support@uni-lab.hk or call service hotline: 0755-86180996.
