1/16/2024 0 Comments Automatic crossbow gif![]() ![]() Since the crossbows are reconfigurable mechanisms, the However, the historical archives have never recorded such an ingenious invention. Its magazine wasĪttached to the frame, which could hold 20 arrows and shoot 2 arrows per Period, it was named the Chu State repeating crossbow. As it was unearthed in the territory of the Chu State in the Warring States ItĬan be dated back to the 4th century BC (Jingzhou Museum, 2014). The earliest repeating crossbow was excavated in Jiangling, Hubei, China. This was aįurther development of the crossbow. Shooting repeatedly, which is called a repeating crossbow. In addition, there was a type of crossbow that had the capability of ![]() One of the longest-lived arms in ancient China. More than 2000 years later, the structure of the crossbow is similar, making it Its function is to stretch the bowstringĪnd keep the elastic energy within the bow and the bowstring. The core technology of a crossbow is the trigger Until the Qing Dynasty (1644–1911 AD), the crossbow was still used and was the essential ![]() Small handheld crossbow was less powerful but more flexible. Compared with the large mechanical crossbow, the The large mechanical crossbow usually combined severalĬrossbows and used mechanical devices to enhance the power and stability of It can be divided into two categories: large mechanical crossbow and small handheld crossbow. Improvement of the crossbow in later generations, the structure and shape of Adding a scale table to the trigger mechanism helps the archer to shoot the target more accurately. Tension than installed in the wooden frame. Of the trigger mechanism installed in the bronze casing can provide higher One is to increase the bronze casing and the other is to carve a scale table with a shooting range onto the trigger mechanism. After the Han Dynasty, there are two modified designs in the Trigger mechanism has no bronze casing and is fixed in the wooden frameĭirectly. Before the Han Dynasty (206 BC–AD 220), the In view of the structures, the development of the original crossbow can be divided into Unearthed trigger mechanism was found in Qufu in Shandong Province, and it can be dated back to the 6th century BC (Zhong, 2008). The original crossbow is The Art of War dated from 498 BC (Needham, 1954). In the Warring States Period (475–221 BC), it There are a lot of ancient documents which recorded informationĪbout the original crossbow. In the Spring–Autumn Period (770–476 BC), the original crossbow had been widely used. WesternĬrossbows are often complex, and several moving parts must have been fabricated. The characteristics of Chinese crossbows are that the parts are easy to re-assemble and are exchangeable. Around the 16th century AD, it spread to Africa and the Americas. Of Eurasia, and more Asian than European. The crossbow is fundamentally an implement of warfare Long periods of time and being inaccurate in shooting (Zhang et al., 2004 Human force, thus remedying the two issues of people being unable to aim for This development improved the bowstring which previously had to be pulled by Tightened the bowstring, it facilitated the aiming and shooting of arrows. Trigger mechanism onto a traditional bow. It was developed by adding the frame and a This could beĭescribed as a developed weapon which used the delayed force of the bow'sīowstring to shoot arrows. In ancient times, an original crossbow was called a “nu”. People's interest in hunting implements continued to develop over the nextįew thousand years, and this influenced the development of human projectile Progressed from throwing stones to using bows and arrows in hunting. Therefore, it is widely believed that prehistoric people's behavior Many arrowheads have been excavated which are made from stones or animalīones. In addition, in ruins dating back to the Neolithic Age, In ruins, stoneĪrrowheads have been unearthed, dating from 1.7 million years ago to 10 000 years ago. The original crossbow evolved from the traditional bow. Two crossbows are presented to illustrate the shooting processes. Proposed to check the constrained motion. The degrees of freedom of two crossbows are Then, topological structures of the original crossbow and Chu State Provided as an example to describe the manufacturing process of the bow. A brief history of the development of the crossbow in ancient China is given. Matrix to present the topological structures of the original crossbow and It is defined as a reconfigurable mechanism. Of the crossbow has a different configuration during the shooting process, After the 4th century BC, the technology of producing crossbows was very sophisticated. Because it used theĮlasticity of the bow and the bowstring to shoot arrows, it was used for It was one of the most frequently used weapons during theĥth century BC to the 18th century AD. In ancient China, people integrated the original bow, theīowstring, and a cam mechanism to develop a powerful weapon which was named ![]()
