Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] Such as Figure 1 to Figure 3 The test system for sound quality of side sliding door opening and closing includes a door opening and closing trigger device, a sound collector, a height-adjustable bracket 7 , a data acquisition front end and a computer 8 . The sound collector is an artificial head 6, and the bracket 7 is a tripod. The artificial head 6 is installed on the tripod through the bottom threaded hole and is located at the required position for testing. It is electrically connected with the computer 8 (in addition, the artificial head 6 can also be directly electrically connected with the computer 8 through a signal line). The door opening and closing trigger device includes a digital speedometer 1, an L-shaped elbow 2, a sleeve 3, a first suction cup 4 and a second suction cup 5; Manual vacuuming is possible; the digital speedometer 1 (an existing ...

Abstract

The invention discloses a testing system and testing method for the sound quality of side-sliding vehicle door opening and closing, comprising a vehicle door opening and closing triggering device, a sound collector, a bracket and a computer; the vehicle door opening and closing triggering device comprises a digital speedometer and is L-shaped. The elbow, the casing, the first suction cup and the second suction cup; the digital speedometer includes a support, two metal needles and a speedometer probe with a speed display function, the support is fixedly connected with the first suction cup, and two metal needles Installed on the support in parallel to each other, the first suction cup can be adsorbed on the side sliding door, the speedometer probe is fixedly connected with one end of the elbow, the straight pipe section at the other end of the elbow is inserted into the casing, and the casing is provided with a Fastening bolts that can keep the straight pipe section and the sleeve relatively fixed, the sleeve is fixedly connected with the second suction cup, and the second suction cup can be adsorbed on the front door adjacent to the side sliding door. By adopting the invention, the acoustic parameters reflecting the opening and closing sound quality of the side-sliding vehicle door can be obtained, and the product development of the side-sliding vehicle door can be guided.

Description

technical field [0001] The invention belongs to the field of sound quality testing of automobiles, and in particular relates to a testing system and a testing method for the sound quality of opening and closing a side-sliding car door. Background technique [0002] The sound quality of the opening and closing of the car door is an important indicator of the car. Customers first contact with a car from the moment the door is opened. A pleasant and comfortable opening and closing sound will give people a feeling of good performance and reliable quality of the vehicle. At present, automobile manufacturers mainly focus on the opening and closing sound quality of forward-opening doors, but less research on side-sliding doors. The sliding door can be pressed tightly by the pressure of the airflow when the car is running, so it is relatively safe, so it is widely adopted by automobile manufacturers; the biggest advantage of the side-sliding door is that it requires less space to o...
