Develop a generation trucks brand new, in which all components and technical solutions are new, involved a high level of demand for quality testing. Many of the tests that subjected the new Volvo FH have focused on customer needs.
"It tata to offer maximum uptime. Customers need to know that the trucks do their job as expected, regardless of weather conditions or operating environments, "explains Kenneth Abrahamsson, Project verification and validation of the new Volvo FH. "It took over a year only to determine the plan verification and validation that defined the different characteristics of the truck had to try," says Kenneth Abrahamsson, Project verification and validation of the new Volvo FH.
"Although the verification plan and test is very sophisticated, the method is very simple to understand. This is to test, measure and improve, and repeat the test again and again until the product meets or exceeds the requirements. Track all bug reports was performed and corrective measures were taken, "continues explaining Kenneth Abrahamsson.
The tests were conducted focusing on aspects like reliability, durability and fuel consumption of the truck. At first, they were tested separately individual components such as the chassis, cabin and electrical system. Once passed all the tests, it was time to test the full truck. The tests were performed in the laboratories of Volvo Trucks and the test tracks of the company, and also in open traffic with trucks tests.
One of the many fields of testing using V to test their trucks is located in Kiruna, northern Sweden. During the winter of 2011 / 2012, the lowest temperature recorded was-there 44 ° C and this frigid weather was perfect to determine how it would behave the new Volvo FH in such extreme conditions. Johanzon Hans was one of the test engineers and ensured that all drivers know what is expected of them.
"These tests are related to the client work. That is, the test drivers use these vehicles in exactly the same way they use their own trucks. The lead, sometimes carrying passengers, sleep in them and verify that start in the morning, even after a night ice cream, "he says.
During the test period, each truck was driven at least 20.000 kilometers icy cold conditions, in which one of the biggest problems is that all components of the truck, from the hardest material to the electrical system, and freeze become brittle. The challenge was to develop components that will support these frigid conditions without failing.
"Ensuring that the truck can not only withstand extreme cold weather, but rapid temperature changes is another challenge in quality. Therefore, normally we drive from northern Scandinavia, where they can register 40 degrees below zero, to the Norwegian coast, where the climate is mild and humid and the temperature often registers positive values. Twenty minutes later, we again drive to the mountains, where the temperature drops again, "explains Hans Johanzon.
In the field tests Hällered near Gothenburg in Sweden, other evidence of various types were performed. A large number of test drivers worked intensively to conduct a series of tests demanding accelerated strength. These tests are the equivalent 10 1.250.000 years and miles on the road. Includes challenging road conditions, such as driving on hills with slopes between 10 and 20 percent and lead to a number of difficult obstacles such as potholes, uneven terrain, paved terrain, slopes and waterways. The test procedures include other elements such as open and close the doors again and again.
One of the toughest parts of accelerated strength testing is to drive the truck on a track durability. In it, the truck is subjected to the same kind of obstacles that are found in normal traffic conditions, but in a much shorter period of time. When driving repeatedly around the track, which raises a wide range of challenging obstacles, the test is greatly accelerated.
Is carried out further in the laboratory accelerated testing Volvo Trucks, which includes a vibration mechanism, and in which the truck is subjected to vibrations continuously for six to eight weeks. For the customer, this is equivalent to driving over one million miles.
Later, track all information and comments from verification testing is done to understand the cause of any failure and to find lasting technical solutions.
Then undergo a new test new solutions and the procedure continues until the specification of the component in question meets the specified requirements for that component.
To also validate the product from the perspective of the end customer, Volvo Trucks also carried out field. "This involves testing the new series Volvo FH in traffic. We have almost 50 trucks driven by customers in Europe, Australia and Brazil. In this way we can cover operating conditions, types of transport, weather conditions and behaviors of different drivers, "explains Kenneth Abrahamsson.
