Automotive Durable Test : การทดสอบความทนทานของยานยนต์
D1368 เรามีส่วนร่วมในการพัฒนาและผลิตผลิตภัณฑ์ยานยนต์ที่มีความแข็งแรงทนทาน มีทั้งวัสดุและการทดสอบที่เน้นการพัฒนาเพื่อปรับแต่งผลิตภัณฑ์ยานยนต์ของคุณให้มีคุณภาพที่ยืดหยุ่น และทรงพลัง การทดสอบความทนทานประกอบด้วย HALT, FMVT, เป็นระบบที่มีความน่าเชื่อถือ และมีคุณสมบัติการทดสอบความทนทานของวัสดุ เช่นการทดสอบแรงดึง, การทดสอบการโค้งงอ, ทดสอบแรงกระแทก Izod เป็นต้น
We engage in the development and production of a robust, strong, durable automotive product for Automotive Durability Testing.
Both materials and development-focused testing is available in order to shape your automotive products into the resilient, powerful assets. Development durability testing includes HALT, FMVT, accelerated reliability options, while materials durability testing features options such as tensile testing, flex testing, Izod impacts, charpy impacts and more.
Testing the Durability of the Product
Once you’ve established the kind of product you need for your machine or business, you want to be sure of the durability of the product. To get this type of data, it must have been through rigorous testing to find out the length of time the product can carry out its function with no damage arising. These tests are set up by simulating the conditions that would ordinarily develop in the products’ lifespan. The rigorous testing simulators can test for any contingency that may develop with your product. The testing that may be carried out, depending on your product, are:
- Permeation – for fuel containers and pipes
- Leakage – for all fuels, liquids and gases
- Mechanical Shock
- Thermal Shock
- Thermal Cycle
- Pressure Cycle
- Tensile – generally referred to as tension testing
- Failure Points
- Component Degradation
- Operational Limits
- Lifetime Span
- Vacuum Cycle
- Slosh – for fuel containers and pipes
- Evaporation Emissions – for fuel containers and pipes
Here is a little bit more information about these different types of testing for durability.
Temperature testing is mainly carried out in laboratories. A reliable testing machine will measure the elevated behaviours of materials when exposed to extreme temperatures. Elevated temperature testing is carried out at 1800 degrees Fahrenheit. This is brought about by setting the product in a furnace with temperatures up to 1800 degrees Fahrenheit and running the computer controlled system to regulate the temperature levels.
When tensile testing, the product is placed into a testing frame where pressure is added to the product. The extensometer measures the strain of the product as the pressure is increased. The data that arises from the strain of the pressure capacity is recorded on a computer system and delivered to you in the test report.
Corrosion can lead to permanent damage to your product. Losing business, health and safety aspects, damage to your reputation and loss of income due to the product corroding is a possible outcome if the product fails the corrosion test. Using high-quality corrosion resistant and high-pressure vessels, your product will go through electrochemical monitoring, 3D laser profiling and scanning electron microscopy to make sure the product is anti-corrosive.
Vibration testing is generally conducted out on the production floor or within a laboratory setting. The vibration testing involves using either an electrodynamic vibration table or a servo-hydraulic shaker. Both these machines will provide shock vibrations to your product using hardware and software that measures the generated pressure and control of the result of the vibration on your product.
Ageing testing uses sped up conditions to advance the ageing process to test the product to its limits. The testing is usually carried out in a laboratory setting where the sped up conditions and continuous stress imposed on the product will determine its lifespan. The ageing testing can be set to your desired frequency, whether it’s two months, two years or five years. The conditions set for the testing will simulate the number of months or years required for your product and display the results in a report. The number of samples you wish to be tested is entirely up to you.
Fatigue testing will assess how a product degrades over time. This test sets out to add force to the product for a repeated number of times until the product breaks. This produces the result of how long the product should last under strenuous conditions. The testing machine is a table top machine that creates the simulated motion in rapid progression to replicate a fatigued condition.
The first signs of fatigue appear in the form of cracks occurring on the product. As the testing continues the cracks become deeper and longer, until the product cannot tolerate the stress anymore. The product will completely break under the pressure of the stress being put on it.
