摘　　要：为解决某型伺服机构的生产研制中真实负载操作复杂,维护困难的问题,提出一种模块化模拟负载平台。通过建立负载数学模型、动态特性测试和谐振频率分析辨识,阐述了模拟负载平台的机械结构、加载控制、惯性负载模块、摩擦负载模块、弹性负载模块和总体方案,并针对性设计了摆角测量模块和力测量模块。经过研究及实践,得以生产出模拟负载平台并成功替代真实负载,动态性能高,测试效率高,满足地面半实物试验中对伺服系统动态特性测试的需求,具有良好的工程应用价值。Based on the background of the batch production research and design of one kind of servo system, one modular simulated load platform is represented in this paper to solve the problems such as operation complexity of the real load equipment and maintenance difficulties. By mathematic load modeling, dynamic characteristics testing and resonance frequency analysis, the mechanical structure, loading control, inertia load module design, elastic load module design and the general plan are introduced in this paper. And also the angular measurement module and force measurement module are designed specifically.By research and experiments, the simulated load platform which has the advantages such as high dynamic performance, high testing efficiency is carried out and can successfully replace the real load equipment. The platform has great application value which can fully meet the requirements of the servo system dynamic characteristics test in the semi-physical ground test.
