Interior Material Versatility Testing in Automotive Industry

Fatigue Resistance Test: The main feature is to pressurize the target test system for a long time, for the purpose of testing the stability of the system, and the duration is generally greater than 1 hour; Fatigue testing is a continuation of user concurrency testing, so the main content is still main module user concurrency and combined module user concurrency. While writing test cases, you need to write multiple test cases under different settings or load conditions. You can refer to the concurrency performance of users. For the design content of test cases, the required test cases can generally be realized by changing the corresponding parameters; fat resistance test casesfollowing rules:

Limit name: 300 users using the system at the same time 3 modules;

Prerequisites: The test client must have sufficient resources;

Operating time: 16 hours of consecutive runs;

Test method: Use LOADRUNNER to record 3 tasks, then start pressurizing the system;

Input action: Task 1, task 2, task 3; duration, task 20 hours, task 2, 21 hours, task 3, 16 hours; number of users; phenomenon;

Fatigue strength testing can be performed using tool automation. Tests, you can also manually write program tests, of which the latter make up a larger proportion. Under normal circumstances, a fatigue test is performed for a certain period of time based on the maximum number of concurrent users the server can accommodatenormally and stably to requests for getting transaction execution flag data and system resource monitoring data. If an error occurs and the test cannot be run successfully, the test indicators will be adjusted in a timely manner, such as reducing the number of users, shortening the test cycle, etc. Another type of fatigue test is to evaluate the current performance of the system. . Based on the number of current users under normal system operating conditions, a fatigue test is performed for a certain period of time.

Large data volume testing: Primarily intended for testing systems that have special database requirements, such as mobile phone SMS services in systems telecommunications salespeople; it can be divided into large volumes of real-time data, mainlyThe goal is to test whether the system can operate stably when there are many users or when certain services generate a large amount of data; testing under extreme conditions is to test whether the system can operate normally when used for a certain time, that is, when it accumulates a small amount of data; the previous The combination of the two tests, when the system has accumulated a large amount of data, some modules that generate a large amount of data in real time can work stably; the following large number of test cases:

Function: The short message table in the database can record all the short messages that cannot be sent in time, and the user can log in. After that, the recorded information can be sent in time;

Large data volume testing can be divided into two types: independent data volume tests for large data volumes for certain system storage, transmission, statistics, query and other services; Comprehensive data volume testing program combined with pressure performance testing, load performance testing and fatigue performance testing. The key to testing on large volumes of data is preparing the test data, and you can rely on tools to prepare the test data.

At present, the speed test is mainly to measure the speed manually for key companies with speed requirements. The average value can be calculated on the basis of several tests and compared with the response time and other indicators measured by the tool.

A \"continuous\" fatigue tester is a machine for the periodic application of pneumatic loads, driven by a programmable load profilethe per PC, which can be applied in either direction up to a load of 460 lb (210 kg).

Standard version includes a 2½\" bore x 10\" stroke tie rod cylinder with center trunnion for lifting, providing rotational motion on a single axis from vertical (straight down) ) backwards towards horizontal (front). The rear end of the cylinder provides neutral force countermeasures when the rod is at mid-stroke and is equipped with a 500-pound capacity fatigue load sensor and adapter plate. Two adjustable manual handles allow floating rotational movement (when attached to a specimen that bends under load) or rigid upward movement (when pressurizing and retracting the specimen). This trunnion mount also provides approximately 6\" of lateral movement. If lateral movement needs to exceed the amount of 6\", the entire vertical support can be bolted tothe base plate and can be moved. .

The bracket provides approximately 30\" of vertical cylinder adjustment, locked in place using a hand screw jack and a pair of adjustable hand clamps on the top of the steam. Below the lower limit of vertical displacement, the support legs are in a more open position so that the test sample is placed directly under the cylinder either pushed by a rod or pulled in a vertical direction, and the The entire stand can be lifted anywhere on the base plate onto different base plates, allowing maximum flexibility of test arrangements.
