英文摘要：

The structure of flexible wire mesh tire for manned lunar roving vehicle is comparatively special. The integrated design of tire drive and transmission is implemented. It consists of assembled aluminum alloy hub, inner spring bump stop and wire mesh tire. Based on the wheel-soil interaction terramechanics and a part-experience method, the calculation of driving power and torque of single wheel is completed. Then the hub driving motors and harmonic reductions gears are selected by considering main technical factors such as mass and power constraints, etc. Finite element analysis of assembled aluminum alloy hub is done according to different conditions of static analysis and dynamic-bend fatigue experiment method. The structure of flexible wire mesh tire is improved by considering the results of finite element analysis. At the same time, the inner spring bump stop is analyzed and the technical flow-chart of wire mesh tire is researched and verified. This provides a technical basis for developing wheel for manned lunar roving vehicle which adapts deformable rough terrain on the lunar surface with large loaded, low power consumption and big driving force.
