Study on the Speed Stability of Wheel Drive Mechanism used in Lunar Rover by Xiao Jie, Zeng Lingbin, Zhang Xiaowei, Liu Dianfu, Zou Huaiwu

“…The 3-stage planetary reducer with closed-loop control is adopted in CE-3 lunar rover wheel drive mechanism.Aiming at the problem that the speed stability of drive mechanism does not satisfy the design requirements,the factors affecting the speed stability of planetary reducer are systematically analyzed,and methods and measures minimizing the inequality of load sharing of planetary gear sets are studied carefully.Through troubleshooting and numerical simulations,the causation is uncovered as follows:the first stage sun gear radial runout exceeds the allowed range.Then two solutions are proposed:the first one is to redesign the first stage sun gear into a floating sun gear,the second one is to improve the machining precision of the first stage sun gear.And the second solution is adopted because it is smaller and lighter than the first one.Then much ground simulation tests which are conducted at the room condition,high-temperature vacuum condition and low-temperature vacuum condition demonstrate that the speed stability of drive mechanism satisfies the design requirements.At last,the effectiveness of the proposed method is validated by the telemetry parameters of lunar rover moving on the moon surface.…”

Distributed trust management scheme based on blockchain in Internet of vehicles by Haibo ZHANG, Yukun CAO, Kaijian LIU, Ruyan WANG

“…Aiming at the security problems caused by the low efficiency and accuracy of malicious vehicle identification in Internet of vehicles, a distributed trust management scheme based on blockchain in Internet of vehicles was proposed.A false information identification strategy was designed by aggregating the scoring information of vehicles, combined with Bayesian inference model.A reputation value updating algorithm was designed by combining the historical interaction information of vehicles and traffic information, malicious vehicles were identified by the reputation threshold.A blockchain was constructed roadside units to realize the distributed storage of traffic data and vehicle reputation values.The traditional proof of work consensus mechanism was improved to dynamically change the difficulty of miner node generating a block through the event level and the number of vehicles involved in scoring, and the waiting mechanism was used to temporarily stop the nodes that had recently blocked from participating in the election process of miner nodes, thus reducing the resource consumption caused by repeated calculations.The simulation results show that the proposed scheme can effectively identify false information, resist the deceptive behavior of malicious vehicles, improve the identification efficiency of malicious vehicles, reduce resource consumption, and is effective and feasible in distributed trust management for Internet of vehicles.…”

Cooperation-based location authentication scheme for crowdsensing applications by Youliang TIAN, Maoqing TIAN, Hongfeng GAO, Miao HE, Jinbo XIONG

“…Utilizing mobile devices to collect location-related data in crowdsensing has the security problem of a location cheating attack.How to guarantee the quality of these sensitive data has become a challenge.In response to this, a location authentication scheme was proposed based on cooperation to detect malicious users who submit false locations.Firstly, users with mobile devices were used to generate location proofs for each other, and a location verification scheme was designed based on distance bounding protocols for obtaining new information by multiple collisions of the same random number, which ensured the user’s location should be unforgeable and achieved the purpose of improving the quality of collected data.In addition, a location proof cooperator select method based on region division and reputation model was proposed which effectively prevented collusion attack and solved the problem of concentration of equity.Meanwhile, the incentive mechanism based on reputation value and task completion time was designed to effectively improve the location proof cooperator efficiency of task completion.Finally, security analysis and performance evaluation indicate that the scheme has proved to be correctness and secure, and the advantages in computational cost and communication overhead.…”
