Tooth Profile Optimization Design of Cup Flexspline Harmonic Drive
Published 2015-01-01“…For the purpose of improving the engagement qualities of harmonic drive（ HD）,taking the HD with the drive ratio 100 as example,the basic conjugated tooth profile for involute tooth profile is calculated based on the modified kinematics method of HD and the elastic deformation of flexspline,the tooth profile optimization design model is established and calculated by using the iteration method of MATLAB,in order to verify the correctness of the aforementioned model,the engagement state of the tooth profile after optimized is studied.The results show that effective conjugate exist domain and effective conjugate tooth profile are found,in order to avoid the interference during the engagement process,the three-dimensional tooth profile must be applied as the conjugate tooth profile.Finally,the correctness of all of the aforementioned model are verified by the characteristics,such as non-interference during the assembly and movement process,more number of teeth participated in engagement and large transmission ratio.…”

RSS localization algorithm based on second-order cone programming in non-line-of-sight environment
Published 2021-03-01“…Aiming at the problem that the accuracy of localization using received signal strength (RSS) in wireless sensor network is insufficient in non-line-of-sight (NLOS) environment, a new robust localization algorithm based on second-order cone programming (SOCP) was proposed.Based on the assumption of the upper bound of NLOS biases, a location equation with robustness to NLOS biases was constructed to suppress the interference of NLOS biases, then convex optimization was used to transform the robust localization problem into a second-order cone programming problem with the intention of accurate estimation, thereby improved the localization accuracy.In addition, the localization problem was extended to the case of unknown transmission power, and an iterative SOCP algorithm was proposed.Simulation results show that the proposed algorithm can effectively solve the problems existing in NLOS localization, and the localization accuracy is better than Newton iteration method, UT method and SOCP method.…”
