【摘要】：针对目前国内激光冲击强化设备工业化程度不高的问题,采用固定光路系统结构形式和模块化设计方法,研制了一款激光冲击强化设备。分析了激光冲击强化设备的设计方案、激光光路布置特点以及系统控制方法,并对激光冲击强化设备技术指标进行了测试。保持室温在(22±2)℃以内,设备开机20 min后,输出最大脉冲能量可达25 J,能量波动范围不超过3%,脉宽在16 ns?20 ns之间连续可调,波动范围在-1 ns?1 ns以内,光束的发散角小于2.5 mrad,光束指向波动小于50μrad,重复频率0.5 Hz?5 Hz可调,光路系统的传输效率约为92%,约束层厚度均匀、且流量连续可控。测试结果表明,激光冲击强化设备的各项性能良好。
[Abstract]:Aiming at the problem that the industrialization of laser shock strengthening equipment is not high at present, a laser impact strengthening equipment is developed by adopting the structure form of fixed optical path system and modularization design method, and the design scheme of laser impact strengthening equipment is analyzed. The characteristics of laser light path arrangement and system control method are also tested. The technical specifications of laser shock strengthening equipment are tested. The laser beam is kept within 22 卤2 鈩，
