| Gusset | 144 | 126 | 8.062 | 10.052 |
| Top cover | 45 | 99 | 8.83 | 13.939 |
| Underframe | 162 | 121 | 9.252 | 10.669 |
| Back wall | 130 | 113 | 9.676 | 11.104 |
| Before enclose | 30 | 23 | 5.518 | 2.246 |
| Rear suspension | 51 | 73 | 1.425 | 1.456 |
| Front suspension | 63 | 82 | 0.655 | 1.606 |
| First cross section | 31 | 23 | 5.151 | 0.591 |
| Second and third cross section | 64 | 44 | 4.542 | 1.449 |
| The 4th cross section | 284 | 112 | 4.292 | 3.388 |
| The 5th cross section | 61 | 62 | 4.812 | 4.445 |
| The 6th cross section | 83 | 42 | 3.305 | 3.170 |
| The 7th cross section | 73 | 81 | 0.962 | 1.098 |
| The 8th cross section | 232 | 108 | 2.473 | 3.073 |
| The 9th cross section | 50 | 83 | 5.154 | 6.765 |
| Back tail longeron | 72 | 30 | 9.629 | 11.058 |
| The aisle | 138 | 116 | 5.411 | 7.088 |
According to last table as can be seen: variation had all taken place in stress and distortion before and after body framwork improved, and just stress is redistributed, and made the skeleton overall stress relative with distortion evenly.Local rod member stress has surpassed the permissible stress of setting, but totally exceeds not quite, still within allowed band.Top cover place, the 4th cross section, the 8th section stress change greatly, are because be in loading point position, cause stress concentration.
Body framwork is touched the attitude analysis:
Vehicle body in travelling is subjected to multiple excitation, and research vehicle body behavioral characteristics performance actv. is analyzed the ride comfort and the fatigue life of automobile, and its purpose is to optimize body structure, touches the attitude frequency and the vibration shape with the control vehicle body.The distribution of body quality, rigidity, damping, the connection mode of member spare are the four elementses of decision vehicle body natural frequency size.Utilize the body framwork finite element model, skeleton has been carried out touching the attitude analysis.
According to last table as can be seen: the former order frequencies of skeleton are very approaching, cause multiple mode of vibration to mix the situation that occurs easily.And the skeleton after improving has drawn back the frequency on former rank relatively.According to the road surface statistical analysis, Uneven road encourages mainly at low frequency range, so each frequency of drawing back low frequency range is very necessary.
According to the test result of above two aspects, we have carried out the loss of weight conceptual design to existing vehicle.Two kinds of about 400KG of contrast model loss of weight (not calculating local reinforcing member).Carried out finite element analysis according to above-mentioned light-weight design scheme, contrast with former body framwork, overall assessment is: the stress of this scheme and deformation state can satisfy the requirement of the strength and stiffness of structure, the local area of high stress that exists, but in tolerance band.
The benefit of body lightening is: reduce use, the reduction oil consumption of material.
The present invention fully guarantees bus body skeleton intensity in sum, the passenger vehicle passive satety is increased, impact resistance is 3-6 a times of day bus, guaranteed passenger's living space, satisfy GB GB/T17578-1998, European ECER66 (guaranteeing passenger's living space) standard fully, and when guaranteeing bus body skeleton intensity, make passenger vehicle weight saving, reach energy-conservation, oil-efficient economic benefit.Simultaneously, above feature also makes driving have safety, stationarity, traveling comfort more.Owing to the car load skeleton adopts the rectangular tube structure, also be easier to carry out arrangements such as low floor design, hommization layout, increasing passenger space, increasing storage room, thereby satisfy many-sided demand of user.
