Simulation And Lightweight Technology Research Of Compression Mechanism Of ZX24 Pure Electric Garbage Truck

Pure electric garbage truck has gradually become the main vehicle for garbage transportation and collection due to its advantages of large compression capacity,good sealing,convenient loading,high automation level and less environmental pollution.But due to the pure electric garbage truck has a lack of endurance mileage and compression performance,the author takes the compression mechanism of a company’s ZX24 pure electric garbage truck as the research object and uses virtual prototyping technology and finite element method to conduct simulation analysis and structure lightweight technology research so as to provide scientific research methods for the design optimization of such products.The main research contents include the following aspects:1.According to the operating principle of sliding scraper compression mechanism,the component composition,point coordinates,filling angle and the maximum filling force of garbage compression for simulating the full-load filling condition are determined,and the multi-body dynamic model of compression mechanism under the full-load filling condition was established by using ADAMS.2.According to the established multi-body dynamic model of compression mechanism,the motion stability of bottom scraper,the actuator force and the load of sliding scraper were analyzed and studied.Meanwhile,the OPTDES-SQP optimization solver embedded in ADAMS was used to make the parametric optimization design of relevant targets.3.Building the finite element models of sliding scraper under the full-load filling condition before and after the optimization of hinge points in Hyper Mesh,and verifying whether the sliding scraper meets the operating requirements of working conditions through the comparative analysis of structural strength and stiffness,and then the optimization conclusions were obtained.4.The methods of size optimization,topology and size integrated optimization are respectively adopted for the further structural lightweight design of sliding scraper under the premise of meeting the requirements of structural tightness,manufacturing process and operating performance,so as to achieve the overall weight-loss goal of compression mechanism.
