Abstract

The multi-body contact model and dynamics model for flexible bearings are established based on the Ansys Workbench software, and the stress and deformation of flexible bearings are analyzed under the conditions of assembly stress and external load. The fatigue life of the inner and outer rings of flexible bearings is analyzed based on the nCode-Designlife software. In addition, orthogonal experiments are designed to explore the relationship between mechanical characteristics and three design parameters of flexible bearings. The results show that the fatigue weak area of the inner ring is located at the outer face of the long shaft, while the outer ring is located at the contact area between the ball and the channel at the long shaft; the maximum radial deformation has a significant effect on the stress of the inner and outer rings. Reducing radial deformation in a certain range and controlling the number of balls are helpful to reduce stress and improve life, which provides reference for the design of flexible bearings.

Abstract

In the long-term work of industrial robot cables,the mechanical properties will be insufficient due to aging,which will affect the normal operation of the robot. In this paper,the thermal aging test was carried out to accelerate the aging of CPE rubber at the same temperature,and the tensile test was carried out to select the tensile strength at break and the elongation at break. The mechanical properties of CPE rubber after aging were studied. The results show that with the increase in aging time,the tensile strength and elongation of CPE break with the aging time,showing a trend of decreasing first and then rising. And the tendency towards the elongation at break is a delay from the tensile strength of the fracture. The slope of the elastic phase of the CPE tensile curve is greatly affected by the aging time,while the strengthening phase is less affected by it. And the slope of the elastic stage decreases rapidly in the early stage of heating,and it picks up later. This can provide some basis for further research to improve cable performance and prolong its service life.

43. REITS: Reflective Surface for Intelligent Transportation Systems

Abstract

Autonomous vehicles are predicted to dominate the transportation industry in the foreseeable future. Safety is one of the major challenges to the early deployment of self-driving systems. To ensure safety, self-driving vehicles must sense and detect humans, other vehicles, and road infrastructure accurately, robustly, and timely. However, existing sensing techniques used by self-driving vehicles may not be absolutely reliable. In this paper, we design REITS, a system to improve the reliability of RF-based sensing modules for autonomous vehicles. We conduct theoretical analysis on possible failures of existing RF-based sensing systems. Based on the analysis, REITS adopts a multi-antenna design, which enables constructive blind beamforming to return an enhanced radar signal in the incident direction. REITS can also let the existing radar system sense identification information by switching between constructive beamforming state and destructive beamforming state. Preliminary results show that REITS improves the detection distance of a self-driving car radar by a factor of 3.63.
