摘要
目的研究一种航天员虚拟训练仿真中手部操作力生成方法。方法假设影响航天员手部操作力的两个因素是合力、合力与扶栏之间夹角,通过设计模拟失重环境下力测量实验进行验证。结果数据分析检验了假设的正确性,并且建立了基于合力、合力与扶栏之间夹角的手部操作力计算模型。结论将本模型应用于航天员虚拟操作训练仿真系统,增强了系统的沉浸感和交互性。
Objective To find out a model of hand operating force for astronaut virtual training. Methods It was supposed that there were two factors effecting on hand operating force, total force and the angle between total force and handrail. Experiment in microgravity simulation was designed to prove it. Results It was proved to be correct with data analysis and the model of hand operating force was founded. Conclusion In the end, the model of hand operating force has been put into the astronaut virtual training system, and the force interaction between astronaut and virtual environment has been implemented to enhance the reality and vitality of virtual training system.
