摘要

Objective Based on the properties of integrated modular avionics equipment, the method of loads decomposition for LRM was studied.Methods By simulation and test method, the temperature and vibration load of LRM were decomposed, and the realization process of both methods was discussed in detail.Result The module loads decomposition method was suc-cessfully applied in an engineering project, and the validity of methods was verified.Conclusion The method of LRM module loads decomposition can be used to guide the loads decomposition of other similar integrated modular avionics equipment, and at the same time to promote the reasonable independent environment test and delivery of LRM module.%目的：根据综合模块化航空电子设备的特点，研究LRM模块的载荷分解方法。方法通过仿真和试验方法，对LRM模块所承受的温度和振动载荷进行分解，并详细论述两种方法的具体实现过程。结果将模块载荷分解方法成功运用于某工程系统中，验证了方法的有效性。结论 LRM模块的载荷分解方法能够指导其他类似综合模块化航空电子设备的载荷分解，推动LRM模块合理的独立环境试验及交付。
