Description
Technical field is the automobile chassis frame structure under the utility model.
At present both at home and abroad to the design of automobile chassis frame all based on empirical design, finite element is designed to assist.And the finite element design is many based on static analysis.Nineteen sixty-five W.G Hurty at first proposes the dynamic properties of soils that modal synthesis method solves large scale structure, and L.J.Howell in 1974 is applied to the roadlice modal synthesis with the method for Lagrange multipliers of E.H Dowell, but only limit is determined displacement and acceleration responsive.For example translated＜U.S.〉M.M Kai Moer in 1985, " modern automobile structural analysis " book that the J.A. Wolf is write, the content of wherein narrating relevant automobile chassis frame is only limited to the modal synthesis technology determines displacement and acceleration responsive.In the vehicle frame finite element analysis of " the automobile CAD " of Beijing Automobile and Motorcycle United Production Co.'s exploitation in December nineteen ninety, calculated static weight, live load is only pressed three times of estimations of quiet lotus.
The damage of automobile chassis frame is because tired causing, vehicle frame is in vibration under the arbitrary excitation during running car, its destruction should be calculated by the random fatigue failure theory, because live load calculation of complex, still multiply by the several times dynamic factor again by bending under the static load and after reversing calculated stress at present, this does not meet actual conditions.
The purpose that the present utility model is created is to change former 1040 types and 1041 types series vehicle frame strength design, thereby improves frame strength, alleviates the weight of vehicle frame, produces good economic benefit.
The fundamental point that the present utility model is created is: the vehicle frame dynamic stress adopts the random fatigue failure theory to be optimized design, has improved the degree of irregularity of existing power, alleviates deadweight, and design-calculated distribution of stress optimum regime is optimized.Two longerons (1) of its vehicle frame are U-steel (4), and h is broad in the middle, and two is little, is variable section.Have 7 crossbeams (2), middle its thickness of 5 pipes (3) crossbeams (2) is generally less than 5mm and greater than 2.9mm, between.The crossbeam (2) of front and back two U-steels (4) and the thickness of two U-steels (4) longerons (1) are all seen Fig. 1 less than 5mm greater than 4.4mm(), between is advisable.

Former 1040 types of Fig. 2,1041 type body frame structure for automotive scheme drawings.
5 crossbeam section forms of light-duty truck central frame beam scheme drawing that Fig. 3 intensity in light weight is high.

Describe concrete structure of the present utility model in conjunction with the accompanying drawings in detail.
The damage of automobile chassis frame is because tired causing, vehicle frame is in the vibration under the arbitrary excitation during running car, its destruction should be calculated by the random fatigue failure theory, because live load calculation of complex, still multiply by the several times dynamic factor at present by bending under the static load and after reversing calculated stress, design-calculated 1040 types in this way, 1041 type vehicle frame (see figure 2)s, wherein 1040 types have 7 crossbeams (2) and 1041 types have 8 crossbeams (2), front and back two U-steel (4) crossbeam (2), middle circle cast (3) crossbeam (2) and its thickness of two U-steels (4) longerons (1) are 5mm.
The light-duty truck vehicle frame of the invention is to be optimized design by the random fatigue failure theory, thereby has improved frame strength, reduces maximum stress, reduces the degree of irregularity of stress, alleviates deadweight simultaneously, the optimum regime that the engineering stress that is optimized distributes.Under vehicle frame processing technology machine condition unmodified situation, remove the 6th crossbeam of the former vehicle frame of 1041 types (2), be that the light-duty truck vehicle frame is 7 crossbeams (2), 5 crossbeams (2) are pipe (3) in the middle of it, its thickness of pipe is (see figure 3) between the two less than 5mm greater than 2.9mm, and two, front and back crossbeam (2) is U-steel (4).Article two, the longeron of U-steel (4), h is small at both ends and big in the middle, is the variable section (see figure 4).To 1040 type vehicle frames behind optimal design, middle 5 pipes (3) crossbeams (2) thickness less than 5mm greater than 2.9mm between the two.Before and after two U-steel (4) crossbeam (2) and its thickness of two U-steels (4) longeron all less than 5mm greater than 4.4mm between the two.Article two, the longeron of U-steel (4), h is broad in the middle, and two is little, is variable section.
The light-duty truck vehicle frame that the utility model is designed, be achieved on former machining production line, reach 1.5 ten thousand kilometers failtests checking after tested, this vehicle frame is not only simple in structure, alleviate deadweight, improve intensity simultaneously, reduce dynamic stress and degree of irregularity thereof, obtain the optimum optimization design, saving in material, cost-cutting is applied, remarkable in economical benefits.
