Description
Technical field
The utility model relates to vehicle passive safety test field, especially relates to a kind of dummy's shoulder force transducer replacement block that is used to replace dummy's shoulder force transducer.
Background technology
Present popularizing along with automobile; It is also more and more frequent that traffic hazard takes place; Therefore improve Automobile Design; Thereby the security performance that improves automobile becomes more and more important problem, owing to can not be used for true man among the experiment, the testing dummy who impact test therefore occurred being used for substitutes true man and makes an experiment.The collision experiment dummy is according to the ergonomics principle, and with the experimental apparatus that special material is processed, it can apish profile and inner structure; Be used to study the degree of impairment of car crass to driver and crew in the car; To the data acquisition and processing (DAP) of dummy's degree of impairment, and compare on this basis during impact test, injury of human exponential sum life-support systems are carried out qualitative and quantitative evaluation; Thereby simulate the injury situation that true man receive, with the security performance of check vehicle.
During occurrence of traffic accident, because the structural design of existing automobile, the energy-absorbing member of automobile side is less; If impact site is very big to passenger's harm at automobile side, thereby particularly important to the check of automobile side security performance; In order to estimate the safety coefficient of automobile side impact, need to gather dummy side head in the side collision process, shoulder; Rib, belly, the injury data of key positions such as hip.Wherein the injury data of dummy's shoulder are by shoulder force transducer module collection output, and the shoulder of general dummy both sides all can be installed shoulder force transducer module, because the side impact test only need be used one-sided shoulder force transducer; The shoulder force transducer module of opposite side will be by idle, and in the impact test, there is the risk of damage equally in idle shoulder force transducer module; And sensor receives temperature, and the influence of humidity is very big, lighting in the test; The energy that collision produces etc. all can more or less exert an influence to sensor; Experiment material has been wasted in the damage of the shoulder force transducer module that causes leaving unused, and has increased experimentation cost greatly.
Like publication number be: a kind of device for side impact recognition or pressure transducer that the Chinese invention patent of CN1822969A provides; Wherein be mechanical switch as the truthlikeness sensor of the corresponding configuration of this pressure transducer, this mechanical switch preferably is arranged in the shell of this pressure transducer.Device for side impact recognition has a pressure transducer and a truthlikeness sensor that is arranged on automobile side, it is characterized by, and the truthlikeness Sensor Design becomes a switch that is attached to the shell of pressure transducer.This patent exists idle shoulder force transducer and has damaged, increased the problem of experimentation cost easily.
The utility model content
