摘　　要：GJB150.15A主要用于指导安装在飞机、直升机、载人航天器、飞机外挂件和地面发射导弹上的装备的加速度试验。由于该类试件一般具有体积大、重量大和重心高等特点,所以标准中推荐使用转臂式离心机进行该类试件的加速度试验。通过对GJB150.15A中推荐的试验参数进行梳理,再结合转臂式离心机的特性,研究了加速度试验方法的实施与样品安装。由于利用转臂式离心机进行加速度试验的危险性、破坏性更大,因而其对试件的安装配重具有更高的要求e目前我国环境适应性工程领域相对缺乏关于该方面的理论基础的研究,故具备较大的开拓空间,通过对该方面的研究探讨,能够有效地指导试验者进行试验操作,并且提升军用装备开展特种环境试验的技术能力。GJB 150.15A is mainly used for the accelerated test of equipments installed on aircraft, helicopters, manned spacecraft, aircraft accessories and ground-launched missiles. Since such samples generally have the characteristics of large volume, large weight, high center of gravity, so it is recommended to use rotary arm centrifuge for the accelerated test of this kind of specimen in the standard. Through the combing of the test parameters recommended in GJB 150.15A,and combined with the characteristics of the rotary arm centrifuge, the method implementation and sample installation of the accelerated test are studied. Because it is more dangerous and destructive to use rotary arm centrifuge to carry out accelerated test, so it has higher requirements for the installation weight of specimen. Due to the relative lack of theoretical basis in the field of environmental adaptive engineering in our country at present, therefore, there is large space for development. The research on this aspect can effectively guide the experimenter to carry on the test operation and improve the technical ability of carrying out the special environmental test for military equipment.
