AI Technical Summary
In existing ground static tests of solid rocket engines, the preload loading method has the disadvantages of small loading force, inability to effectively avoid thrust oscillation, cumbersome operation, high manpower consumption, and unsuitability for confined environments.
The preload loading device, which employs a lever mechanism and weight suspension, achieves multi-stage amplification of preload through the lever mechanism. Combined with a length adjustment mechanism and a load-bearing plate transfer mechanism, it can adapt to the rapid loading of different engine models.
It effectively suppresses thrust impact and oscillation, improves test accuracy, enhances loading reliability and ease of operation, and is suitable for confined environments.
