The article aims at reviewing the drop regions (DR) of the launch vehicles (LV) separating parts (SP) and methods of their determination. The DRs include sea and land areas; going beyond them is associated with a number of environmental, economic, and political factors. Their combination dictates the need to ensure the safety of the people, transport, infrastructure, and environment from the negative impact of LV SPs and fuel residues. The Monte Carlo method is mostly used to determine the impact areas. It enables an estimation of the probability of the SPs of LVs falling in certain areas, constituting the DRs. These points are varied according to a set of different initial parameters. The methods of controlling the impact areas are contingently divided into engineering (based on a change in the design appearance of the LV), mathematical (which includes the changes in or optimization of the LV’s trajectory or its SP), and “soft landing” (implying the return of the LV’s to the spaceport or to a certain prepared area). The present analysis can be used as a starting point when choosing a method for determining and controlling the projected LVs and the SPs’ area of impact.

The development of artificial intelligence (AI) technology and the Internet of Things (IoT) platform in recent years has allowed image detection systems to efficiently and gradually process data. The following study will be done in this paper to examine the image detection of AI based on mechatronics IoT technology. It is necessary to first describe the substance of mechatronics, the IoT, and other technologies, incorporate them into the IoT, and then examine and discuss the IoT's application potential. The second stage explains the fundamental ideas and various digital image detection algorithms that are really used in processing, and on the basis of these ideas, it suggests a number of automatic recognition processing approaches. In the third stage, different photos are classified using the Support Vector Machine (SVM) classifier based on AI and neural network technology, and the feature vectors of the target area are obtained through analysis and calculation. These are the conclusions: (1) The fusion of mechatronics and IoT technology has helped the AI industry innovate and grow to some level, which is helpful for fulfilling the fundamental criteria of an environment for intelligent picture recognition and detection. ( 2) An intelligent simulation model for image detection with recognition accuracy of over 95% and features of high speed, high precision, and high automation has raised the bar for detection and intelligent machine vision technology in China. (3) When SVM and neural networks are tested, the absolute error of the classification target value is very low, allowing them to meet the requirements for detection accuracy following error processing and a recognition rate of 90%.

The traditional cross-section form of the current electric truck frame impedes the further exploration and lightweight potential of the frame's overall mechanical performance. This paper introduces a method that integrates the Analytic Hierarchy Process (AHP) with the Criteria Importance Through Intercriteria Correlation (CRITIC) to establish interactive weights for multi-objective joint topology decision-making in frame design. It involves devising a novel, extrusion-compatible structural design for the frame's longitudinal and cross beams using aluminum alloy 6061T6 material. In comparison with a steel frame of an electric truck, this novel aluminum alloy frame, designed using the multi-objective joint topology optimization method combined with dimensional optimization, not only enhances the overall mechanical performance but also achieves a weight reduction of 36%. The interactive decision-making method, a fusion of AHP and CRITIC proposed in this study, can offer valuable guidance for the lightweight design of complex mechanical structures.
