摘　　要：石英挠性加速度计石英摆片挠性梁发生断裂,是导致加速度计失效的主要因素。在实际应用中,系统发动机点火产生的冲击谱力学环境,是力学环境适应性考核的主要指标。为了使石英挠性加速度计能够满足系统冲击谱力学环境要求,通过对石英摆片模态、耐受冲击环境进行分析,分别对两种相同材料的冲击谱试验安装基座进行模态分析,优化冲击谱试验安装基座设计,按冲击谱力学环境进行试验验证,对试验数据进行分析。试验结果表明,优化后的冲击谱试验安装基座更接近系统冲击谱试验环境。Quartz pendulum is the core component of the quartz flexible accelerometer,and the fracture of its flexible beam will lead to the failure of the accelerometer.In the actual application,the shock spectrum mechanical environment generated during the ignition of the engine is the main indicator of the mechanical environment adaptability.In order to ensure that the quartz flexible accelerometer can meet the requirements of the shock spectrum mechanical environment,the modal of the quartz pendulum and the shock resistance environment were analyzed.Two types of shock spectrum test mounting base of the same material were analyzed,and the design of the mounting base was optimized.Verification test was carried out and the test data was analyzed.The experimental results showed that the optimized shock spectrum test mounting base was closer to the shock spectrum test environment.
