Description

A kind of automobile body-in-white impact test is with mobile trolley used
Technical field
The utility model relates to automobile body-in-white impact test technical field, specifically a kind of workable, favorable repeatability, collision impact is stablized, test figure precision is high, can obtain a kind of automobile body-in-white impact test of the FC& SC performance of automobile body-in-white with mobile trolley used.
Background technology
In order to alleviate the harm that automobile collision accident causes the mankind; China has successively formulated GB11551-2014 " passenger protection of frontal crash of vehicles " (replacing former GB11551-2003 " passenger protection of passenger car head-on crash ") about head-on crash and side collision and GB20071-2006 " passenger protection of manned vehicle " standard, checks and rates the collision safety performance of vehicle under whole vehicle state.But the construction cycle of car load is longer, and cost of development is higher, the testing expenses of complete automobile collision are also higher, have certain restriction to Automobile Enterprises fast Development new product.
Automobile body-in-white absorbs the collision energy of the overwhelming majority in an impact, plays conclusive effect to automotive safety.For making body of a motor car have good energy absorption characteristics, the basic thought of vehicle safety design is exactly effectively absorb collision energy at the deformable region of vehicle body, and impact force is transmitted in dispersion, to guarantee effective living space of occupant.
Along with the requirement of energy-saving and emission-reduction is more and more stricter, car load enterprise often applies new material new process to alleviate the weight of body in white, realizes the lightweight of body in white, and corresponding car load generally needs to carry out the optimization of many rounds and verification experimental verification has come.Comparatively speaking, the construction cycle of body in white is shorter, expense is low, car load is compared in the FC& SC testing expenses carrying out body in white also to be had and significantly reduces, and Automobile Enterprises is in the trail development stage or early stage at Vehicle Body Development of body in white, just can carry out front or side collision, obtain collision performance, and then be optimized improvement in time, and need not wait until that the complete automobile collision demonstration test stage just goes to pinpoint the problems, will greatly reduce construction cycle and the R&D costs of automobile product.
Existing impact test technology can adopt track slide unit or the middle chassis of GB20071-2006 " passenger protection of manned vehicle " to load automobile body-in-white, but track slide unit crashes and hits too much constraint, differ greatly with actual tests operating mode, larger to track impact damage in test, only can carry out the lower central collision of speed, side collision test cannot be completed; Chassis heavier-weight in GB20071-2006 " passenger protection of manned vehicle ", only can carry out the lower central collision of speed, install higher and can not adjust, and cannot complete the side collision test of body in white.
Find the literature search of existing correlation technique, CN202008434U discloses " a kind of front trolley collision test device ", mainly describes the chassis frontal collision test device of the actual head-on crash process of accurate simulation vehicle, for the exploitation of constrained system.CN103512721A discloses " Adjustable-type trolley for impact test ", mainly describes a kind of Adjustable-type trolley for impact test, for the exploitation of constrained system.CN2703686Y discloses " Frontage-car collision testing device for automobile ", is mainly used in the dynamic process under collision process simulates any one full scale vehicle collision mode, is applicable to constrained system exploitation.CN204128771U discloses " a kind of multi-functional crash test table vehicle ", is mainly used in the side statutes test of car load, for installing honeycomb aluminum and carrying out collision impact to car load; CN203101015U discloses " a kind of novel front longitudinal impact test apparatus ", mainly describes the test adopting car load side impact test chassis to carry out car longeron.
In sum, existing impact test chassis mostly is the test unit carrying out positive restraint system development, or for the test chassis of car load side collision, due to the difference with actual condition, and impact velocity, highly, heavily quantitative limitation cannot carry out body in white collision performance test.
