Challenges of Applying
Accelerated Life Testing to a Machine
Applying accelerated life testing to a complex system comprised of several different mechanical and electrical technologies is challenging.
Individual device testing is not an option, full systems testing is required. Common strategies include high ambient temperature testing and extreme vibration testing. With these extreme conditions applied it may be difficult to operate the system fully, which limits the accuracy of any ALT. As a result, ALT is commonly performed in conjunction with Ongoing Reliability Testing (ORT).
