Customer Testing Requirements

The customer required a horizontal Shock Response Spectrum (SRS) testing system capable of accurately and repeatedly simulating aerospace shock environments.

However, the customer’s products vary significantly in size and configuration. To meet the testing requirements of different products, CME developed a customized dual-table solution.

The system is equipped with two interchangeable test tables, 600 × 600 mm and 600 × 1000 mm, allowing customers to perform different types of tests without purchasing two separate systems.

By replacing different table configurations, the system can achieve different maximum acceleration levels and corner frequencies to meet the specific testing requirements of various products.

Note: The maximum acceleration capability and corner frequency vary depending on the selected table size.

The main requirements included:

• Horizontal shock excitation capability
• Interchangeable dual-table configuration
• Response frequency range from 10 Hz to 10,000 Hz
• High response acceleration output capability
• Accurate SRS profile reproduction
• Stable testing performance under different load conditions
