Description

Car white vehicle vehicle body bending stiffness test restraint device
Technical field
The present invention relates to vehicle detection technical field, be specifically related to a kind of car white vehicle vehicle body bending rigidityTest restraint device.
Background technology
Body in white (BodyinWhite) has referred to welding but the vehicle body before application not, does not compriseThe movement parts such as car door, bonnet. Body in white adds that interior exterior trim (comprises instrument board, steering hub column, seatChair, front and rear windshield, rearview mirror, beater or beat-up, water tank, headlight, carpet, interior trim backplate etc.)And just composition vehicle body truly of car door, bonnet, luggage-boot lid and electronic apparatus system, OKInside be called trimmedbody, the vehicle body installing, adds on this basis chassis and (comprises and startingMachine, gearbox, transmission system, brakes, suspension system, gas extraction system etc.) just formed wholeCar.
Bending stiffness and torsional rigidity are one of important performances of body in white structure, the test of body stiffness,Need to set up a set of science, reliable test method, and vehicle body restraint device there is very important workWith. Traditional body in white stiffness test platform adopted constraint fixed form substantially, made institute's measuring car bodyRigidity value is subject to stand impact, and in assembling process, can vehicle body be produced and preloaded, and in process of the testSuffer restraints device restriction of body distortion.
The key point of measuring body in white rigidity is the way of restraint and the displacement transducer precision of vehicle body. OrderBefore, domestic each Automobile Enterprises and relevant colleges and universities all carry out have body in white curved, turn round stiffness test, andThe precision of displacement transducer is substantially all higher than 0.01mm, and restraint device is not quite similar, and difference justBe the restriction to vehicle body spatial degrees of freedom. Currently used mode was constraint formula, i.e. white carThe kinematic pair quantity that each shock absorber installation place of body rigidly fixes or introduces is very few, causes constraint.

The free degree of carrying out the free components of spatial movement is 6, determines that a member is in space coordinatesPosition need 6 location parameters independently, in other words, member can have 3 solely along three reference axisVertical movement and around three reference axis have 3 independently rotate. When phase after member composition spatial kinematic pairAll suffer restraints mutually, and still maintain certain relative motion after two member component movement pairs.Kinematic pair type used in space mechanism is more, conventionally classifies by retraining number in kinematic pair again.The kinematic pair that constraint number is 1 is called 1 grade of pair, and the kinematic pair that constraint number is 2 is called 2 grades of pairs, successivelyAnalogize, the kinematic pair that constraint number is 5 is called 5 grades of pairs. The free degree=all movable structures of space mechanismThe constraint number that the part free degree-all kinematic pairs are introduced, its formula is:
F=6n-5P5-4P4-3P3-2P2-P1
In formula: n is movable part number; P1, P2, P3, P4, P5 are respectively 1-5 level kinematic pairNumber.

F=6n-5P5-4P4-3P3-2P2-P1-k
=6×4-5×1-4×0-3×6-2×0-1×0-2
=-1
In formula: n is movable part number; P1, P2, P3, P4, P5 are respectively 1-5 level kinematic pairNumber; K is isolated degree of freedom.
Visible, in existing best-of-breed technology scheme, still had constraint.
Prior art scheme, due to ball pair, the revolute pair limited amount introduced, existed approximately body in whiteBundle, its shortcoming is as follows:
A) do not meet space mechanism's free degree constraint requirements, introduced the pact that exceedes vehicle body six-freedom degreeBundle, and then can preload its generation in the time that fixing vehicle body is installed; Each stage of Vehicle Body Development all needsTest rigidity value, retrain formula device owing to can produce not of uniform size preloading in clamping process and crossLotus, will certainly reduce the comparativity of rigidity value that each stage surveys.
