摘要:

为解决某飞机轮速信号测试中出现的数据缺失、曲线阶梯状不平滑及数据回零问题,分析轮速信号测试原理及测试系统结构,结合待测轮速信号特性,提出轮速信号测试优化方法,包括备份设计、直流隔离、周期测试及指标优化等。并针对轮速信号地面状态特性,设计一种信号测试链路检测方案。试飞测试验证结果表明,备份数据误差低于0.5%,数据曲线平滑,可消除数据回零现象,设计的轮速信号测试链路检测方案可行,有助于试飞航前检查。

Abstract: In order to solve the problem of missing data, unsmooth step of curve and turn-to-zero of data in the test of wheel speed signal of an aircraft, the principle of test of wheel speed signal and the composition of test system are analyzed. Considering the characteristics of the wheel speed signal to be tested,the optimized test method of wheel speed signal is proposed. The backup design, DC isolation, cycle testing, and index optimization are included. Besides, a signal link detection scheme is designed in accordance with the characteristics of the wheel speed signal on the ground state. The verification results of flight test show that the backup data error is less than 0.5%, and the data curve of the wheel speed is smooth. Also the turn-to-zero phenomenon of data is eliminated. And the signal link detection scheme of wheel speed signal is feasible, which is helpful for pre-flight inspection in test flight.
