In the field of mechanical equipment manufacturing, the focus of research and development is not on weight reduction, but on how to choose between the rigidity and performance of components (such as strength or flexibility). For this contradiction, lightweight is one of the best solutions. The problems associated with lightweight were initially considered and systematically studied in aircraft manufacturing in engineering. Therefore, lightweight has been greatly developed in aviation research and has played an increasingly important role in construction machinery. This paper presents a brief description of the current status of lightweight in machinery by reviewing some significant progress made in the last decades. Potential research topics are also discussed from the four aspects of material, structure, bionics, and manufacturing, and they forecast the development trend of lightweight in the future construction machinery. The entire body of literature about the field is not covered due to the limitation of the length of paper. The scope of this review is limited and closely related to the development of lightweight technology in engineering applications.

Spectrum Data

Gearbox load spectrum is the data basis for gearbox fatigue life prediction and strength verification. As the amount of load spectrum data increases exponentially and the demand for sharing increases, it is necessary to introduce database technology to store and manage load spectrum data. In this paper, the collection and processing of load data and the compilation of load spectrum are introduced in turns firstly. Then it sums the development and research status of database technology and the technical route of combining load spectrum database up secondly. Moreover, the current status of load spectrum database and the design steps of load spectrum database are summarized. Finally, the development trend of load spectrum database research is generalized and the prospect is put forward.

Competitive aerobics is a sports project which combines music, aerobics, difficulty and performance as the whole, and takes health, strength and beauty as its movement characteristics. Competitive aerobics is one of the sports that is dominated by skills, and the technical requirements are higher. Through the analysis of the existing literature, the current research on the difficulty of aerobics is only in the general qualitative description and experience summary. So far, there is no comprehensive analysis of the evolution of the competitive gymnastics articles, in the theoretical aspects of the study which is more general, limited. In this work, the method of digital image processing is used to focus on the evolution of the difficulty of aerobics. Combining the rules of the international competitive aerobics competition in each cycle, this work analyzes the statistical data of the movement difficulty of the aerobics championships, discusses the difficulty of aerobics development and evolution process, from summing up the characteristics of the development of difficult movements,the development trend of difficult movements of competitive aerobics is scientifically predicted.
