Abstract

The invention provides a lever type chain pressurized device and a lever type chain pressurized method for measuring climbing force of an insect or a small animal. The lever type chain pressurized device for measuring climbing force of an animal is characterized by comprising a lever mechanism, a balanced pressurizing mechanism, a movable pressurizing mechanism, a charge coupled device (CCD) shooting system for observing the animal, and an observation desk for accommodating the tested animal, wherein one end of the lever mechanism is connected with the animal, and the other end of the lever mechanism is connected with the balanced pressurizing mechanism; and the balanced pressurizing mechanism is connected with the movable pressurizing mechanism which is used for changing the arm of force of the lever mechanism. The device is ingenious, practical and high in adaptability, stably applies force, is low in interference, wide in variation range and accurate, digital and automatic in measurement and can be used for measuring planar climbing force of the insect.

Description

technical field [0001] The invention relates to a lever-type chain pressurized insect or small animal crawling force measuring device and a measuring method, belonging to the field of insect or small animal crawling force measurement. Background technique [0002] During the 3.5 billion years of evolution and survival competition, animals have formed many excellent geometric structures, lightweight material topologies, simple and effective control methods, and functionally rich surface structures. These structures, materials, and motion control methods make animals superior to modern mechanical systems in terms of smooth motion, flexibility, environmental adaptability, and high energy efficiency. Through the interaction between the soles of their feet and the ground, they realize motion behaviors such as driving, stabilizing, and maneuvering. In particular, people often see flies, ants, crickets and other animals crawling quickly on smooth surfaces, and even hang upside dow...
