What is the structure of clothing test

What is the structure of clothing test fake people? In order to improve production efficiency, in order to reduce human costs, many apparel companies will use dummy to test clothes related features. At this time, many people are very curious, how can people can test the related data related to clothing? Here, Shanghai has tried to tell you that this is related to the structure of the fake. Below, you bring a detailed introduction to everyone.

What is the structure of a fake person in clothing test? Shanghai Thousands of tries tell you that clothing testing can not only avoid the risk and physiological impact on personal safety, but also have repeated tedious tests for long-term repetitions, and contribute to cost and improve accuracy and Uniform standards. According to different research purposes, clothing test fake people mainly include warmer fake people, soft dummy and combustion dummy. Among them, the warm body dummy is used to simulate the hot and humid exchange process between the human body, the clothing and the environment; the software dummy is used to study human pressure comfort; the combustion fake people are used to simulate the hot ring

Evaluate fire protection equipment. In response to the development and development of these clothing tests, the simulation of the fake people must be considered for the fake people to consider their activity. At the same time, with the development and practical application of mechanical automation technology, clothing test fake people should not be limited to simulation of posture and static action simulation, but should analyze the activeity of clothing test fake people. And design, more comprehensive simulating the series of dynamics of human motion, so that it can better meet the needs of various experiments.

What is the structure of a fake person in clothing test? Shanghai Thousands of truths, the fake people used to carry out the cost of clothing are usually the structure:

Drive

For fake people in clothing tests, electric drive is a relatively ideal way due to their morphological characteristics and speed and dynamic control. The power drive has the advantages of convenient power supply, rapid response, large driving force, convenient and flexible control of signal detection. The drive motor can use an AC or DC servo motor and accompany the deceleration mechanism. However, it is best to use a large torque, low speed motor, and simplify the mechanism and improve control accuracy. At the same time, it should take into account the conditions under special conditions and take corresponding measures, such as the combustion fake people used in high temperature environments must consider the effect of thermal radiation.

The motor of the human body is dynamic in a bone as a lever, the joint is a rotating shaft, and the muscles shrink is power. The joint is formed mainly includes types such as condyle, sliding, pivot, and saddle. Clothing testDummy's capabilities usually requires articular articles, elbow joints, hip, knee joints, and spine, etc., which are mainly flexible, internal and abranges, and internal and except. Despite the higher the degree of simulation of the dummy and the real person, the actual application of the clothing experiment and the performance of the fake people's design plan, the fake person can actually actively use the rotary joint, using a single or more The rotation joint can basically meet the needs of its different motion forms. Of course, the size of each joint portion motor of the dummy should try to meet the size requirements of the corresponding human joints.

The structure of the fake person of the clothing test is similar to the human body, consisting of head, torso, upper limbs and lower limbs. The shoulder joint, elbow joint, hip joint, knee joint and ankle joint are coupled. In order to achieve the requirements, at least 3 degrees of freedom should be each degree of freedom in the upper limbs and lower extremity in the case of trunk. Since the fake people can actually be used to reproduce the movement of the human body and their posture, only need to move within a fixed spatial range, without considering the dynamic balance similar to the walking robot, therefore in the structural design The freedom of the dummy should be reduced as much as possible to simplify the operation and control system. In addition, it is necessary to consider the convenience of the clothes.

Since the prostitute is a space open chain mechanism, the motion of each joint is independent, In order to reproduce the motion trajectory of the limbs, multiple joint motion coordination is required, and multiple separate servo systems need to be organically coordinated, and the procedures set by the computer software are required to complete the required motion. The fake man's control method should be trajectory. The hand feet of the fake person should meet the requirements of the experiment according to the trajectory and motor speed of the teaching. In the experiment, the fake person often requires a different action posture, so it is also necessary to install the brake in each joint site, and the brake should be as possible to be in the system-driven input to ensure its high positioning accuracy.
