Abstract

The invention discloses a car drum test soundproof room, comprising a work room internally provided with a drum test bench, wherein two opposite side faces of the work room are respectively provided with a room door, and door panels of the room door are made by adopting PVB sandwich glass; a wall body of the work room is a soundproof wall, and the soundproof wall comprises a perlite sound absorption panel, a vacuum glass layer and a cement and sawdust sound absorption panel which are arranged in sequence from inside to outside; a part between the perlite sound absorption panel and the vacuum glass layer is filled with glass wool, and a part between the vacuum glass layer and the cement and sawdust sound absorption panel is filled with glass wool; the work room is further internally provided with a temperature adjusting device. The invention aims to provide the car drum test soundproof room for solving the problem that greater noise pollution is generated in a workshop in an existing drum test process, and achieving the aim of isolating drum test to reduce noise pollution in the workshop.

Description

technical field [0001] The invention relates to the field of motor vehicle testing, in particular to a soundproof room for automobile drum tests. Background technique [0002] Automobile braking performance is an important indicator and must-check item of the technical conditions of automobile operation safety, which is directly related to road traffic safety. Among the traffic accidents of automobiles, the proportion of accidents caused by the technical failure of the braking system is very large. Therefore, the national standard GB7258-2004 "Technical Conditions for Motor Vehicle Operation Safety", GB18565-2001 "Comprehensive Performance Requirements and Inspection Methods for Commercial Vehicles", GB / T16739.1-2004 "Opening Conditions for Automobile Maintenance Industry Part 1: Complete Vehicles "Maintenance Enterprise" and other standards require mandatory inspection of the braking performance of automobiles. GB7258 stipulates that road test or bench test can be used fo...
