| Abstract: |
| Objective To study the formulation of vibration test condition for tactical missile in highway mobile transport environment. Method According to measurement data of transportation test on a tactical missile, statistical analysis and power spectrum analysis were taken to establish the tactical missile highway and off-road transportation vibration environment condition on the basis of four types of main frequencies, including frequency of suspension, frequency of tire, constraint frequency of missile and frequency of equipment installation. Results The method presented in this paper predicted the vibration environment conditions of navigation system in missile and control host in launching truck. The result was compared with test result on sports car in the test site. It showed that the method was correct and reasonable. Conclusion By the contrasts with GJB150A and MIL810G, it shows that the method is flexible and convenient, and can adapt to the different equipment in missile and launching truck. |
