Silicone rubber has been widely applicated in the electrical field, especially used as insulation materials, due to its excellent physical properties. However, the performance of silicone rubber will decline with its aging process leaded by plenty of factors. There's lack of methods for overall nondestructive characterization of the aging degree of silicone rubber in use presently. In this paper, the thermal aging experiment of silicone rubber is designed, and the nonlinear coefficient of the sample is measured by nonlinear ultrasonic method during the aging process, the change of the nonlinear coefficient of the sample during the aging process is analyzed, the rule of thermal aging of silicone rubber is summarized, and the feasibility of using the nonlinear coefficient as the aging characterization of silicone rubber is discussed.

Legged robots possess redundant degrees of freedom and multiple footholds, making them highly promising for applications in disaster rescue, material transportation, and planet exploration. However, most previous studies have focused on continuous terrains, whereas walking in unstructured terrains such as plum-blossom piles present higher demands on robot posture control. This paper proposes a quadrupedal robot for gait control during walking in plum-blossom piles. The overall control process of the method is presented, followed by an analysis of the gait control of the quadruped robot. This includes the use of a PD controller to simulate the spring damping effect, the stability control of the robot's body through control target decomposition, and the gait control of individual legs using Jacques' matrix support phase control, combined with trajectory control to complete the swing phase of gait control. Additionally, an acceleration function is introduced to provide a buffering effect for posture adjustments of the quadruped robot. The proposed approach is evaluated using Webots simulation software, including simulation settings, results, and their interpretation. The results demonstrate the successful realization of motion control in complex terrains.

In response to the problem that the validation and evaluation of SAR active jamming effectiveness is more complicated and target detection of SAR image is seldom applied to active jamming, a method of SAR image active jamming detection based on image grayscale features is proposed in this paper. Herein, the principle and process of SAR image target detection algorithm processing, based on pulse coupled neural network are discussed. Through the simulation experiment, the active jamming region can be detected in the SAR jamming image.
