Dynamic riding-driving circumstance human body physiological character and biomechanics testing platform

Abstract

The invention discloses a dynamic driving environment human physiological characteristics and biomechanics test platform which mainly consists of a dynamic excitation system, a three-dimensional digital adjustable seat system, a three-dimensional adjustable driving mechanism and a human physiological characteristics and biomechanics test system. The invention can simulate the dynamic environment (vibration environment) of automobiles, which means to implement the stepless frequency conversion, the amplitude, the frequency fixation and frequency sweep vibration for the variable acceleration; simulate the posture operation of the automobiles in various driving environment; measure the human physiological character indexes of the human electromyography signals, the human arterial blood flow, the human blood pressure response, the human heartbeat number of a driver, etc., and the vibration response of every human part, the contact stress of a human-chair interface and the body pressure distribution of human buttock and back; study and comprehensively test the human physiological characteristics and the human biomechanics of the driving postures of different populations. Through the stimulation on a dynamic driving environment human physiological characteristics and biomechanics test system, scientific data required by the automobile human-machine interface design for populations with different shapes can be obtained.

Description

technical field [0001] The invention belongs to the technical field of ergonomics and relates to an experimental test device, in particular to a test platform for human physiological characteristics and biomechanics in a dynamic driving environment. Background technique [0002] The automobile is one of the greatest inventions of the 20th century. Since Karl Benz successfully developed the world's first car in 1886, the car has experienced more than 120 years of development. During this hundred years of development, the automobile industry has grown from scratch and written an important chapter in the history of modern human civilization at an astonishing speed. As a product of social development, human civilization and scientific progress, automobiles have made great contributions to the progress of human civilization and social and economic development. [0003] At present, the number of cars in the world has exceeded 600 million, with an average...

Among the above-mentioned studies, there is no case of integrating ergonomics and biomechanics to study quantitative ergonomics methods

In 2005, Xi’an Jiaotong University designed a biomechanical test platform for car driving positions. Although it has realized a partial integration of ergonomics and biomechanics, and provided some quantitative methods for the design of human-machine interface, it is not suitable for dynamic environments (vibration environments) The human-machine system and human physiological characteristics and human biomechanical characteristics in the driving environment, that is, the important influence of human fatigue and human comfort, have not been considered, and the test methods for human physiological characteristics and human biomechanical characteristics are relatively limited.
