ABSTRACT:Objective To develop a 400g-t centrifuge for simulating compound environmental test to implement centrifugal-vibration and centrifugal-temperature tests. Methods The technical requirements were analyzed in details, the design of the overall structure, the main drive and control and key components were performed. In addition, the system configuration measurement equipments for static and dynamic balance and the static balance controller were designed. Results The designed static balance controller could adjust 6 t load. Interfaces for compound simulation test were preserved, so that compound environmental tests including centrifugal-vibration and centrifugal-temperature tests could be done with this system. Conclusion The 400 g.t centrifuge for simulating compound environmental test meets the required technical performance, thus satisfying the need of engineering application and scientific research.%目的：研制一种容量达到400g-t的复合环境试验模拟离心机，能够实现离心-振动、离心-温度等复合环境模拟试验的开展。方法分解离心机的技术指标，进行总体部件设计、主驱动控制设计以及关键部件设计。系统配置静、动平衡检测装置，同时设计静态平衡调节装置。结果设计的静态平衡调节装置最大能调节6t负载。系统预留多种复合模拟试验接口，可以实现离心-振动、离心-温度等复合环境模拟试验的开展。结论设计的400g-t综合环境试验离心机达到设计指标，满足工程应用与科学研究需求。
