Embodiment Construction
[0034] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the public implementation manners of the present invention in detail with reference to the accompanying drawings.
[0035] The two-dimensional unfolding zero-gravity simulation scheme based on constant-force springs disclosed in the present invention overcomes the problems of large additional inertia, complex system, and slow system response introduced by traditional zero-gravity simulation deployment methods for space mechanism products. It solves the problem of two-dimensional zero-gravity simulation on the ground of existing space agency products. Among them, the constant force spring is a contact-shaped scroll spring whose output load (tension) is basically kept constant with the increase of deformation. It has good dynamic response, constant load, high energy storage density, small volume, and low friction loss. Etc. In the free sta...
