Description
Technical field
The present invention relates to a kind of test fixture, particularly relate to a kind of automobile power assembly suspending part destructive power test fixture and tensile test apparatus.
Background technology
Automobile power assembly suspension system is one of most important safety component of automobile, and its Main Function is stationary engine and wheel box, engine and wheel box is connected firmly on vehicle body and vehicle frame by mounting bracket or support arm.Therefore, suspension support arm bears the load that engine driving torque produces on the one hand, also bears simultaneously and encourages produced load by road load.The load environment of suspension support arm harshness requires that it has higher intensity, and the important tests evaluating support arm intensity is the test of support arm destructive power.Figure 1 shows that the suspension support arm 1a of certain engine in prior art, support arm one end is connected with engine by bolt hole 2a, and the other end is connected with vehicle body by suspension.The test of support arm destructive power fixes support arm one end by bolt hole 2a, applies a directed force F progressively increased at the support arm other end, as shown in Figure 1, until the effect F of record is support arm destructive power during support arm fracture.
Traditional support destructive power test structure, please refer to shown in Fig. 2.In the figure, tensile test apparatus 3a drives joint flange 4a and force-guided stem 5a to move up and down by servomotor, and suspension support arm 1a one end is bolted on tensile test apparatus mounting base 7a, and the other end is connected on force-guided stem 5a by test fixture 6a.Can be bolted or weld between test fixture 6a with force-guided stem 5a.Force-guided stem 5a drives at the servomotor of tensile test apparatus and moves up and down, thus suspension support arm 1a is broken or is broken, power when tensile test apparatus built-in sensors can read support arm destruction and displacement.
In the above-mentioned this test method of Fig. 2 display, because test fixture 6a is connected by bolt or welding manner with force-guided stem 5a, belongs to and be rigidly connected, therefore there is Planar Mechanisms when part stress is out of shape, inconsistent with the actual loading of part on automobile.Under the actual loading border of car load, usually suspension support arm 1a connects vehicle body by suspension, suspends as elastomeric material, has good elasticity because rubber stiffness is less, can be out of shape after being subject to load, therefore suspends support arm and is connected with vehicle body and is not rigidly connected.Conventional test methods stressing conditions, can with further reference to Fig. 3 and Fig. 4.As shown in these figures, in test under the effect of directed force F, tested parts suspension support arm 1a and force-guided stem 5a moves to dotted line position, because test fixture 6a and force-guided stem 5a is rigidly connected by bolt or welding manner, angle then in figure between nearly test fixture place suspension support arm 1a and force-guided stem 5a remains unchanged, and stressed leading angle α is equal with rear both angle β.Cause owing to being rigidly connected force-guided stem 5a and tested parts to suspend this degree of freedom of angle of arm room restrained, in test, will inevitably moment of flexure be produced, and in fact there is not this moment of flexure caused because of Planar Mechanisms in automobile power assembly suspending support arm.As shown in Figure 3, moment M 1 can cause tested parts failure mode and complete vehicle test inconsistent, and by the interference of M1, the destructive power causing this test to record is inaccurate, proves that this jig Design causes error of test data more than more than 20% by lot of experiments.Meanwhile, because moment M 2 acts on force-guided stem, therefore tensile test apparatus may be damaged when serious.
Support arm destructive power is tested for evaluation support intensity, is ensured that vehicle safety, the check aspect such as designing quality, optimal design are significant, but in view of traditional experiment device and test method, to there is test findings inaccurate, and easily produce the power of horizontal direction and cause experimental facilities to damage, therefore needing badly and these problems above are researched and solved.
